Commercial Contracts in Australia: A Complete Legal Guide

What Is a Commercial Contract?

A commercial contract is a legally enforceable agreement between two or more parties acting in trade or commerce. It records the bargain — what each side will do, what each side will pay or receive, what happens if performance fails, and how disputes will be resolved. In Australia commercial contracts are governed by the common law of contract, the Australian Consumer Law in Schedule 2 to the Competition and Consumer Act 2010 (Cth), the Sale of Goods Act 1958 (Vic) and equivalents in other States, the Personal Property Securities Act 2009 (Cth), the Privacy Act 1988 (Cth) and (from 9 November 2023) the strengthened unfair contract terms regime that applies to most small-business standard form contracts.

The term "commercial contract" is generic. It covers supply agreements, distribution agreements, services agreements, software agreements, employment contracts, contractor agreements, agency agreements, franchise agreements, leases, finance and security documents, joint venture and shareholders' agreements, confidentiality deeds, settlement deeds and deeds of release, licences, terms of trade and the specialist contracts used in particular industries. The principles in this guide apply across the field; industry-specific overlays are addressed towards the end.

Formation: The Traditional Elements

The traditional elements required to form a binding contract at common law are:

1. Offer. A statement by one party of the terms on which it is prepared to be bound, capable of acceptance. Offers must be distinguished from invitations to treat (for example advertising, price lists and most tender invitations).
2. Acceptance. Unqualified agreement to the offer on its terms, communicated to the offeror. A purported acceptance that varies the offer is generally a counter-offer.
3. Consideration. Something of value moving from each party — money, goods, services, or a promise to act or refrain. Past consideration is generally not good consideration. A document executed as a deed does not require consideration.
4. Intention to create legal relations. Presumed in commercial dealings between businesses and displaceable by clear words such as "subject to contract" or "binding in honour only".
5. Certainty and completeness. The essential terms must be sufficiently certain and complete to be capable of enforcement. Agreements to agree essential terms are often unenforceable.

Capacity, authority and legality operate as further requirements. The parties must have legal capacity (minors, persons of unsound mind and unincorporated entities have particular rules); the signatory must have actual or ostensible authority to bind the relevant entity; and the contract must not be illegal or contrary to public policy. Not every signed document is enforceable, and unsigned or oral arrangements can bind the parties depending on the facts — including exchanges by email or through conduct evidencing agreement.

Parties, Authority and Execution

Identifying the correct legal entity for each party is fundamental. A company is a legal person identified by its ACN; a registered business name is not a legal entity; an ABN is a tax registration number and not a legal entity in itself. Trustees contract in their capacity as trustee of a named trust; partnerships contract through their partners; individuals contract in their personal capacity. Getting the party identification wrong can leave the intended obligor without an enforceable obligation, or expose the wrong entity to liability.

Companies may execute documents under s 127 of the Corporations Act 2001 (Cth) — a permitted, not exclusive, method that engages the assumptions of due execution in ss 128 and 129 in favour of counterparties without actual knowledge of the contrary. Section 110A permits electronic execution (including of deeds) and split-execution by different signatories, and companies may also execute under a common seal or through a duly authorised officer, attorney or agent. Where an individual signs on behalf of a company, verify the authority (director, secretary, attorney under power) and record the capacity in which they sign. Guarantees given by directors or related parties are independent obligations and should be identified as such.

Written Versus Oral Agreements

Many commercial contracts in Australia do not have to be in writing to be binding. Oral contracts are enforceable, as are contracts recorded in emails, purchase orders, online checkout flows and conduct evidencing acceptance. However, certain contracts must be in writing (or evidenced in writing) to be enforceable, including:

• contracts for the sale or disposition of land, under section 126 of the Instruments Act 1958 (Vic);
• certain guarantees and other agreements caught by Statute of Frauds provisions;
• security interests under the PPSA (a written security agreement is generally required for a security interest to attach and be enforceable against a third party);
• franchise disclosure documents under the Franchising Code of Conduct;
• certain financial services disclosures under the Corporations Act 2001 (Cth);
• retail lease disclosure statements under the Retail Leases Act 2003 (Vic);
• credit contracts regulated by the National Consumer Credit Protection Act 2009 (Cth);
• assignments of copyright, which must be in writing signed by or on behalf of the assignor (Copyright Act 1968 (Cth) s 196);
• most powers of attorney; and
• any contract the parties have agreed must be in writing to bind them.

Even where writing is not legally required, it is commercially essential. Oral contracts are difficult to prove, and the discipline of putting an agreement in writing forces both parties to think through the terms informal arrangements always leave unsaid — price, payment, termination, dispute resolution and IP.

Standard Form Contracts and the UCT Regime

A standard form contract is one prepared by one party and offered to the other with little or no genuine opportunity to negotiate. Website terms, supplier credit applications, equipment hire, most subscription agreements, cloud services agreements and many small-business supply arrangements are standard form contracts.

From 9 November 2023 the unfair contract terms regime in Part 2-3 of the Australian Consumer Law has imposed civil penalties on businesses that propose, apply or rely on unfair terms in standard form contracts with consumers and with small businesses. A party is a small business for these purposes where it has fewer than 100 employees or annual turnover under $10 million; the earlier upfront-price ceiling has been removed. The current maximum civil penalty for a body corporate is the greater of $50 million, three times the value of the benefit obtained from the contravention, or 30% of adjusted turnover during the breach period. Whether a particular term is unfair — causing significant imbalance, not reasonably necessary and causing detriment if relied on — is a fact- and context-specific question for the Court. Every standard form template in active use should be reviewed against these criteria.

Negotiated Agreements

Negotiated agreements are contracts where both parties participate in setting the terms — long-term supply arrangements, joint ventures, IT implementations, M&A documents, financing. The unfair contract terms regime does not apply where the contract is not standard form, but the broader doctrines of unconscionability under ss 20 and 21 of the ACL, misleading or deceptive conduct under s 18 and equitable doctrines (duress, undue influence) continue to apply.

Heads of Agreement, Letters of Intent, Term Sheets

Pre-contractual documents go by various names — Heads of Agreement, Letter of Intent, Memorandum of Understanding, Term Sheet — but the legal questions are the same: which parts are binding, which are not, and what happens if the parties never sign the long-form contract? The Australian authorities classify pre-contractual documents using the four Masters v Cameron categories (with a further fifth category recognised in later cases), and whether the parties intend to be immediately bound is a question of objective construction.

The practical drafting rule is to make the binding / non-binding distinction explicit clause by clause. The binding parts typically include confidentiality, exclusivity, costs and governing law; the non-binding part is the commercial deal itself, expressed as "subject to contract" and "subject to satisfactory due diligence". For deeper treatment of pre-contractual documents in business acquisitions see our complete guide to buying a business in Victoria.

Governing Law, Jurisdiction and Arbitration

Governing law, jurisdiction and arbitration clauses are distinct. A governing law clause selects the substantive law that governs the contract; a jurisdiction clause selects the court (and may be exclusive or non-exclusive); an arbitration clause replaces court litigation with private adjudication under agreed rules. Even a well-drafted clause does not necessarily displace mandatory Australian statutes (for example the non-excludable consumer guarantees under the ACL, the PPSA, or provisions of the Corporations Act) or the Court's discretion in urgent applications for injunctive relief. Where the counterparty is offshore, consider enforceability, sanctions and export-control exposure.

Contract Interpretation

Australian courts construe contracts objectively by reference to the text, context and purpose of the document. Entire agreement, integration and no-reliance clauses may narrow the scope of pre-contractual statements taken into account, but they do not automatically exclude claims for misleading or deceptive conduct under s 18 of the ACL, rectification for genuine common mistake, or implied terms that meet the legal test in the relevant category. Careful drafting of definitions, use of consistent terminology and elimination of internal contradictions reduce interpretation risk substantially.

Contract Review Before Signing

Every commercial contract should be read in full before it is signed. That obvious rule is broken constantly — executives sign supplier terms without reading them, sales staff sign credit applications without reading them, founders sign investment documents without reading them. The cost is invariably paid later in disputes over clauses that nobody noticed at the time. Material contracts — those of long duration, high value, with indemnities, restraints, IP issues, security interests, automatic renewal or unusual termination mechanics — should be reviewed by a commercial lawyer before signing.

Due Diligence

Due diligence is the disciplined process of verifying what is being bought, sold or agreed before the contract is signed. The scope depends on the transaction: an asset purchase requires legal, financial and operational due diligence on the target business; a long-term supply contract requires due diligence on the supplier's financial position and performance history; a software agreement requires due diligence on data security, sub-processing and uptime.

For business acquisitions and major transactions, due diligence is set out in detail in our complete guide to buying a business in Victoria and our guide to business sale agreements in Victoria. Diligence findings typically inform the disclosure letter (limiting warranty exposure), specific indemnities (covering known issues) and conditions precedent (matters that must be resolved before completion).

Key Commercial Clauses

Every commercial contract should address the following clause families. The depth depends on the value and duration of the contract, but the headings are essentially constant.

Payment Provisions

The price (or formula for calculating it), GST treatment and any gross-up, whether prices are inclusive or exclusive of GST and the tax-invoice mechanics, currency, timing and method of payment, disputed-invoice procedure, set-off rights, interest on overdue amounts, the consequences of non-payment (suspension of supply, termination, enforcement of security) and any security for payment (deposits, bank guarantees, parent-company guarantees). No single interest rate or payment period is standard; the contract needs to state its own terms and align them with the parties' invoicing and cash-flow expectations.

For construction contracts the Building and Construction Industry Security of Payment Act 2002 (Vic) imposes a mandatory progress-payment regime with statutory adjudication that cannot be contracted out of; payment provisions must align with the Act or risk being unenforceable.

Deliverables and Scope

The contract should specify what is being delivered — goods, services, work, software, data, licences — to what standard, in what quantities, to what specifications, in what location, by what deadline, and by what acceptance mechanism. Vague scope is the single largest source of implementation disputes in IT and construction contracts.

Time Obligations

Time obligations cover start date, milestones, completion date and consequences of delay (extensions of time, liquidated damages, termination). Whether time is "of the essence" — a concept that may elevate a time obligation to a condition — depends on the contract and should be used deliberately, not by default.

Warranties, Representations and Consumer Guarantees

A warranty is a contractual statement of fact about a particular matter — that the goods are fit for purpose, the seller owns what it is selling, no litigation is on foot, financial statements are accurate. Breach of warranty typically gives rise to a claim for damages, not automatic termination (unlike breach of a condition or a repudiatory intermediate term). Warranties are commonly limited by time, amount, de minimis and basket thresholds and by a disclosure letter listing matters the buyer accepts. Representations are pre-contractual statements that may give rise to remedies for misrepresentation or, under the ACL, for misleading or deceptive conduct — the drafting of "no-reliance" clauses does not automatically extinguish s 18 exposure. The statutory consumer guarantees under the ACL apply where the statutory criteria are met and cannot be contracted out of, with only limited restriction of remedies permitted under s 64A.

Indemnities

An indemnity is a contractual promise to compensate another party for a defined loss on the terms of the clause. The trigger, the loss covered, the causation standard, the treatment of mitigation and third-party claims, control of the defence, the interaction with proportionate-liability rules and available insurance, the cap and any time limit are all governed by the wording. An indemnity does not automatically override a liability cap, cover the beneficiary's own negligence, or reach unrelated third-party claims — those outcomes turn on the drafting. Uncapped, broadly worded indemnities in standard supplier terms are among the most dangerous clauses for unwary signatories and should be scoped and capped at pre-signing review.

Limitation of Liability

A limitation of liability clause caps a party's liability under the contract, often by reference to a dollar figure, the price paid, insurance proceeds or fees received in a defined period. Exclusions of indirect, consequential, special or loss-of-profit damages are common. The effectiveness of any exclusion or cap depends on incorporation, construction and mandatory statute — including s 64 of the ACL (which prevents exclusion of the consumer guarantees), the unfair contract terms regime, unconscionability and (in some cases) contra proferentem construction of broad exclusions. There is no rule that liability for negligence, consequential loss or all liability can always be excluded or capped. Liability caps and indemnities should be drafted together so their interaction is clear.

Force Majeure and Frustration

Force majeure is a creature of contract, not a general Australian doctrine. Whether a pandemic, war, natural disaster, government order, supply disruption, cost increase or delay excuses or suspends performance depends on the drafting — the defined triggering events, notice requirements, the consequences (suspension, extension of time, mitigation, termination after a long-stop date) and any obligation to use reasonable endeavours to overcome the event. Frustration is a separate and narrow common-law doctrine that discharges a contract only where performance has become radically different from what was agreed; increased cost, hardship or inconvenience are generally not enough. Neither concept operates automatically.

Confidentiality, IP and Data

Confidentiality clauses define the confidential information (with sensible exclusions for information already known, in the public domain, independently developed, or required to be disclosed by law or regulator), permitted uses, permitted disclosees under flow-down obligations, duration (including survival for defined periods or perpetually for trade secrets), equitable remedies, and return or destruction of information on termination.

IP arrangements should distinguish background IP (owned before or independent of the contract) from project IP (created in performance of the contract), and identify whether IP is assigned or licensed and on what terms. An assignment of copyright must be in writing signed by or on behalf of the assignor under s 196 of the Copyright Act 1968 (Cth). Moral rights of individual authors should be addressed by written consent where relevant. Joint ownership of IP is rarely a good idea because joint owners cannot deal independently without each other's consent.

Where a contract involves handling personal information about identifiable individuals and a party is an APP entity under the Privacy Act 1988 (Cth), the Australian Privacy Principles apply — currently to entities with annual turnover above $3 million and to specific categories regardless of size, with reforms progressively expanding coverage. Contracts should address flow-down APP obligations, cross-border disclosure under APP 8, eligible data breach notification under Part IIIC, security obligations, retention and destruction and audit rights. Health information, credit information and Tax File Numbers attract additional regimes. There is no universal rule that GDPR applies — that depends on the targeting or monitoring test under EU law.

Restraints of Trade and Non-Compete Clauses

A restraint of trade seeks to restrict a party's future activity — competing, soliciting customers or employees, or dealing with confidential information. Restraints are prima facie unenforceable and are only enforced to the extent they are reasonable to protect a legitimate business interest, having regard to duration, geographic scope and activities restrained. Enforceability is ultimately a question for the Court on the facts. Under the Restraints of Trade Act 1976 (NSW) a court has express power to read down an overbroad restraint; other jurisdictions rely on cascading or severance drafting, the enforceability of which is not guaranteed. The Australian Government announced proposed reforms in the 2025–26 Budget to ban non-compete clauses for certain workers, with an intended 2027 start subject to consultation and legislation passing Parliament. As at 21 July 2026, the proposal should not be described as an operative statutory ban; current legislation and official Treasury material must be checked when advising on an employee restraint.

Personal Property Securities (PPSR)

The Personal Property Securities Register is the national online register of security interests in personal property (broadly, all property other than real estate and specified exclusions) established by the Personal Property Securities Act 2009 (Cth). Contracts that in substance create a security interest — retention of title supply, certain leases and bailments of goods (a PPS lease), consignments, and charges over receivables — may require PPSR registration; a purchase money security interest (PMSI) has technical timing and priority rules that must be met for its priority advantage to apply. Registration does not create ownership, and a PPSR search does not guarantee that the grantor has clean title; it evidences registered security interests. Unperfected security interests can vest in the grantor on insolvency under s 267 of the PPSA. For the fuller treatment see our PPSR explained guide.

Assignment and Novation

Assignment is the transfer of one party's rights under a contract to a third party. The benefit of a contract is generally assignable unless prohibited by the contract, statute or a personal-service character; the burden cannot be assigned and can only be transferred by novation, which requires the agreement of the outgoing party, the incoming party and the counterparty. Standard practice is to permit assignment to related entities and to require consent (not to be unreasonably withheld) for any other assignment. Novation is the mechanism used on sale of a business to transfer contracts from the seller's entity to the buyer's entity — see our guide to business sale agreements in Victoria.

Termination Rights

Termination rights commonly include termination for convenience (for long-term contracts, with notice), termination for cause (material breach not remedied within a defined cure period), termination for insolvency events, termination on change of control, termination on prolonged force majeure, and termination on other defined trigger events. Distinguish contractual termination from common-law repudiation, breach of condition and breach of an intermediate term that is serious enough to justify termination — the legal tests differ and the wrong election can itself amount to repudiation. Cure-notice regimes should be followed strictly.

Termination generally does not erase accrued rights, and post-termination clauses (confidentiality, IP, indemnities, dispute resolution, survival) operate only to the extent the wording or their nature requires. Insolvency-triggered termination rights are subject to the ipso facto stay under Part 5.1, Part 5.2 and Part 5.3A of the Corporations Act 2001 (Cth), which can restrict the enforcement of certain insolvency-based termination and self-help rights while the stay applies.

Default Provisions, Liquidated Damages and Penalties

Default provisions identify the events that constitute a default, the cure period, the notice requirements and the consequences (acceleration of payments, termination, enforcement of security, drawdown on bank guarantees).

A liquidated damages clause specifies the amount payable on a defined breach — typically delay in completion — and is enforceable if it can be characterised as compensation for the innocent party's legitimate interests, and not merely as security for performance out of all proportion to those interests. Under current Australian penalty doctrine (developed in the High Court's decisions in Andrews v ANZ and Paciocco v ANZ) a clause is not valid merely because it is labelled "liquidated damages" and is not void merely because it is not a precise pre-estimate of loss; the test is a broader legitimate-interests analysis assessed at the time of contracting.

Dispute Resolution Clauses

A well-drafted commercial contract states how disputes will be resolved before they arise. Tiered clauses commonly provide for good-faith negotiation between nominated senior individuals, then structured mediation under the rules of a recognised body, then either arbitration or litigation in an agreed jurisdiction. Tiered clauses may be enforceable if sufficiently certain — vague obligations to "negotiate in good faith" without more can be unenforceable. Carve-outs for urgent injunctive relief (restraint enforcement, freezing orders, search orders) should be preserved. Limitation periods keep running during pre-litigation steps unless expressly tolled. For the practical workflow see our guide to resolving a business dispute before court and our guide to letters of demand.

Mediation

Mediation is a facilitated negotiation with a neutral third party. It is non-binding (the parties settle only if they agree), generally confidential and often faster and cheaper than litigation. Its usefulness depends on the willingness of the parties, the preparation of the mediator and the shape of the dispute.

Arbitration

Arbitration is a private adjudication by an agreed arbitrator under agreed rules — ACICA, the Resolution Institute, the ICC or the SIAC. Domestic arbitrations are governed by the Commercial Arbitration Act 2011 (Vic) and equivalents; international arbitrations by the International Arbitration Act 1974 (Cth). Awards are binding and internationally enforceable under the New York Convention. Advantages include privacy, choice of arbitrator, international enforceability and procedural flexibility; disadvantages include cost, limited appeal rights and procedural formality.

Court Proceedings

Court proceedings are the default if no other mechanism is agreed. In Victoria the principal courts for commercial disputes are the Magistrates' Court (claims generally up to $100,000), the County Court (unlimited civil jurisdiction, subject to specific carve-outs) and the Supreme Court (including the Commercial Court list). The Federal Court has parallel jurisdiction in matters arising under federal legislation — the Corporations Act, Competition and Consumer Act, Fair Work Act, intellectual property statutes and corporate insolvency.

Electronic Execution and Digital Signatures

The Electronic Transactions Act 1999 (Cth) and State equivalents (in Victoria, the Electronic Transactions (Victoria) Act 2000) provide that an electronic signature satisfies a general legal requirement for a signature where the method identifies the signatory and their intention, is appropriately reliable, and the recipient consents.

Companies may execute documents electronically under s 110A of the Corporations Act 2001 (Cth), including deeds and split-execution by different signatories, and s 127 continues to be a permitted method of execution that engages the assumptions of due execution in ss 128 and 129. Some documents — certain powers of attorney, statutory declarations and specified registrable instruments — have additional or different rules; check the applicable regime before relying on electronic signing. Specialist platforms (DocuSign, Adobe Sign, PEXA) can build technical compliance and audit trails into the signing process.

Deeds Versus Contracts

A deed does not require consideration, must be executed with the additional formalities required by law and (in Victoria) is subject to a 15-year limitation period under s 5(3) of the Limitation of Actions Act 1958 (Vic) for actions on a specialty, compared with 6 years for actions on a simple contract. Deeds are used for guarantees, releases, restraints of trade given without separate payment, deeds of variation and any document where consideration is uncertain or the parties want the longer limitation period. Individual execution of deeds is governed by the Property Law Act 1958 (Vic); company execution is governed by the Corporations Act 2001 (Cth), including ss 127 and 110A.

Common Drafting Issues

The recurring drafting issues we see in practice are almost always preventable:

• ambiguous defined terms (a term used inconsistently across the document);
• inconsistent terminology (the same concept named differently in different clauses);
• uncapped indemnities in standard supplier terms;
• missing or ineffective limitation of liability clauses;
• vague payment terms (no due date, no interest treatment, no consequences of non-payment);
• missing GST treatment and no clarity on gross-up or tax-invoice mechanics;
• absent or unworkable termination clauses;
• absent dispute resolution clauses, defaulting to expensive litigation;
• IP ownership left unsaid;
• restraints of trade drafted more broadly than any legitimate interest supports;
• auto-renewal without meaningful notice;
• annexures referenced but never executed;
• use of undefined verbs such as "endeavour" and "best efforts";
• signing on behalf of the wrong entity (particularly where groups of companies share a trading name);
• failure to attach schedules and exhibits on execution.

Australian Consumer Law Overlays

The Australian Consumer Law in Schedule 2 to the Competition and Consumer Act 2010 (Cth) overlays every commercial contract with consumer-protection obligations. The principal areas of overlap are:

• Unfair contract terms. Terms in standard form consumer and small-business contracts that satisfy the statutory test are void, and the business proposing, applying or relying on them is exposed to civil penalties (currently up to the greater of $50 million, three times the value of the benefit obtained, or 30% of adjusted turnover during the breach period for a body corporate).
• Consumer guarantees. The statutory guarantees under the ACL cannot be contracted out of where they apply, and only limited restriction of remedies is permitted under s 64A for supplies not of a kind ordinarily acquired for personal use.
• Misleading or deceptive conduct. Section 18 applies to conduct in trade or commerce and is not extinguished by entire-agreement or no-reliance clauses.
• Unconscionable conduct. Sections 20 and 21 apply to statutory unconscionable conduct in trade or commerce, with civil penalties available.

Good Faith

Australian law has not conclusively recognised a universal implied duty of good faith across all commercial contracts. Whether such a duty is implied depends on the contract, its subject matter and the jurisdiction. Express good-faith clauses are common and enforceable, but the concept is interpreted by reference to the drafting and context. Where the parties want particular behaviour (cooperation, disclosure, reasonable endeavours, non-obstruction) it is safer to specify it.

Personal Guarantees and Security

Personal guarantees given by directors or related parties are independent obligations from the underlying contract. Execution formalities, adequate disclosure, variation and release provisions, and the effect of equitable doctrines (unconscionable dealing, undue influence, Yerkey v Jones-style spousal-suretyship principles) require care. A director does not become personally liable merely because a company defaults — personal liability depends on statutory grounds (for example insolvent trading under s 588G of the Corporations Act), an executed guarantee, or a director being party to the underlying obligation.

Insolvency and Contract

Contracts cannot override the Corporations Act 2001 (Cth) or the Bankruptcy Act 1966 (Cth). Statutory demands under s 459E, voidable transactions in liquidation, statutory set-off under s 553C, PPSA vesting under s 267 and the ipso facto stay under Part 5.1/5.2/5.3A operate regardless of contractual wording where their statutory criteria apply. Drafting should acknowledge those regimes rather than assume they can be excluded.

International and Supply Terms

Incoterms allocate delivery, risk and cost between seller and buyer in international goods contracts, but they operate only when expressly incorporated and only in the version identified (for example Incoterms 2020). Sanctions, export controls, customs, tax and product regulation are transaction-specific and require separate analysis. Choice of law and jurisdiction, enforcement of foreign judgments and arbitral awards, and currency and payment mechanics all require particular attention in cross-border contracts.

When to Involve a Lawyer

Take advice before signing any contract that is material to the business — including long-term or high-value contracts, those containing indemnities, warranties, restraints, security interests, IP terms, personal-information handling or unusual termination mechanics, and standard form templates the business issues to customers or suppliers. Pre-signing review is typically far cheaper than disputing the same clause after the relationship has broken down. Standard form templates should be reviewed periodically and after material changes in the law — the 2023 unfair contract terms reform being a recent example prompting wholesale review across the Australian SME sector.

Industry-Specific Contracts

Several industries have statutory overlays that change the analysis materially:

• Construction. Building and Construction Industry Security of Payment Act 2002 (Vic) — mandatory progress-payment regime, statutory adjudication, no contracting out; Domestic Building Contracts Act 1995 (Vic) for residential building work.
• Franchising. Franchising Code of Conduct — disclosure document, cooling-off rights, restrictions on restraints, marketing-fund accounting.
• Retail leases. Retail Leases Act 2003 (Vic) — disclosure statements, mandatory minimum terms, prohibited clauses.
• Financial services. Corporations Act 2001 (Cth) — AFSL holders, product disclosure statements, design and distribution obligations.
• Telecommunications and energy. Telecommunications Consumer Protections Code; National Energy Retail Law.
• Commonwealth procurement. Commonwealth Procurement Rules; specific contract templates required for government dealings.
• Commercial property. See our guide to buying commercial property in Victoria for the property-law overlay.
• Employment. Fair Work Act 2009 (Cth), modern awards, enterprise agreements — see our workplace investigations guide for the procedural overlay.

Practical Contract Checklist

Before signing any commercial contract, check that each of the following has been considered and documented:

1. the correct legal name and ACN/ABN of each party;
2. the authority of each signatory to bind the entity;
3. the price, payment terms, GST treatment and interest on overdue amounts;
4. the scope of work, deliverables and acceptance criteria;
5. the timing obligations and consequences of delay;
6. the warranties given and their limits;
7. any indemnities given or received and their caps;
8. the overall liability cap and exclusions;
9. force majeure and the events covered;
10. confidentiality and the duration of the obligation;
11. IP ownership and licensing (and any required copyright assignment in writing);
12. privacy obligations and APP flow-down where applicable;
13. PPSR registration where security interests are created;
14. assignment and novation restrictions;
15. termination rights, notice periods and surviving clauses;
16. dispute resolution mechanism and governing law;
17. execution method (deed or contract) and applicable formalities;
18. annexures and schedules attached and consistent; and
19. insurance and security required of the counterparty.

Common Misconceptions

"A contract is not binding until both parties sign." Not always — an oral agreement or email exchange can bind the parties before any formal document is signed, depending on the Masters v Cameron analysis and the facts.

"Standard terms protect me." Not always — standard form contracts with consumers and small businesses are subject to the unfair contract terms regime, and standard exclusion clauses cannot exclude the statutory consumer guarantees.

"Signing 'subject to contract' means I'm not bound." Not always — the effect depends on the objective construction of the whole document; isolated use of the phrase can be ineffective if the surrounding drafting is inconsistent.

"There is an implied duty of good faith in every Australian commercial contract." Not settled — the position is contract- and jurisdiction-specific. If good faith matters, write it in.

"Electronic signatures are not as good as wet-ink signatures." Not correct in general — the Electronic Transactions legislation and s 110A of the Corporations Act give electronic signatures legal effect for most documents, including deeds executed by companies. Some documents remain subject to different or additional rules.

Frequently Overlooked Risks

• uncapped indemnities buried in supplier terms;
• auto-renewal clauses with short opt-out windows;
• change-of-control clauses triggering termination on a corporate restructure;
• exclusive jurisdiction clauses requiring litigation overseas;
• flow-down obligations requiring back-to-back terms with sub-suppliers;
• retention of title clauses without PPSR registration;
• broad assignment clauses allowing the counterparty to assign to a competitor;
• step-in rights of financiers under tripartite agreements;
• moral rights consents not obtained from individual creators of IP;
• cross-default clauses linking unrelated contracts; and
• survival clauses keeping obligations alive long after the contract ends.

Illustrative Scenarios

Supplier credit application. A Victorian retailer signs the standard credit application of a national wholesaler. The application contains a director's personal guarantee in the small print, a broadly worded indemnity for loss the supplier suffers in collecting overdue amounts, and a retention of title clause registered on the PPSR. When the retailer subsequently enters voluntary administration the director's exposure and the supplier's PPSR priority fall to be determined on the drafting and the statutory regime. Pre-signing review would have scoped the indemnity and clarified the guarantee.

IT implementation contract. A services firm signs a standard-form software implementation contract without legal review. The scope clause is vague, acceptance criteria are undefined and the liability cap is measured by fees paid in the prior twelve months. When the implementation fails the customer's practical recovery is materially limited by the drafting. Pre-signing review would have tightened scope, defined acceptance and recalibrated the cap.

Sale of business. A family business is offered for sale. The Heads of Agreement provides for a long negotiation period for the long-form sale agreement but contains binding confidentiality and exclusivity. During the exclusivity period the buyer discovers an issue and walks away. The seller has been kept out of the market and the binding exclusivity clause prevents a damages claim. Pre-signing review would have shortened the exclusivity, negotiated a break fee, or both. For the deeper workflow see our guide to business sale agreements in Victoria and our guide to buying a business in Victoria.

Death of a director-shareholder. A private company has two equal shareholders. There is no shareholders' agreement and no buy-sell mechanism. One shareholder dies. The deceased shareholder's shares vest in the executor, who has no interest in the business. The parties cannot agree a price and the position is resolved only after prolonged negotiation. A properly drafted shareholders' agreement with an insurance-funded buy-sell can materially shorten that process. See our shareholders' agreements guide, buy-sell agreements explained and our guide to what happens to a company on the death of a director or shareholder.
