A barter or contra deal can be a powerful way for Australian businesses to exchange value without cash changing hands — but the Australian Taxation Office has strict rules about how barter transactions must be treated for GST purposes. Both sides of a barter are taxable supplies under the A New Tax System (Goods and Services Tax) Act 1999, each party must issue a tax invoice, and each must account for GST based on the agreed market value. Our free Australian Barter Agreement template handles all of this: it records what each party is providing, the agreed values for GST, delivery timelines, quality warranties under the Australian Consumer Law, and what happens if one party does not perform. Protect your contra deal with a proper written agreement.
What Is a Barter Agreement (Australia)?
A Barter Agreement, sometimes called a contra deal or exchange agreement, is a written contract in which two parties agree to exchange goods or services with each other without cash payment — or with only a small cash payment to balance any difference in value. Instead of paying money, each party provides something of equivalent value to the other. Common examples include a web designer exchanging a new website for accounting services, a photographer swapping photography for marketing consulting, or two businesses providing each other with advertising in a contra arrangement.
In Australia, barter transactions are treated as genuine commercial transactions for tax purposes. The A New Tax System (Goods and Services Tax) Act 1999 (Cth) treats each side of a barter as a separate taxable supply. If either party is registered for GST, they must account for GST on the market value of their own supply — even though no cash is changing hands. The Australian Taxation Office's Tax Ruling TR 2010/1 specifically addresses GST on barter and exchange transactions.
A written Barter Agreement serves several critical functions. It records the agreed valuation of each party's supply, which is essential for GST compliance and income tax reporting — both the supply made and the supply received must be declared at market value. It specifies delivery dates and performance standards, creating legal obligations that can be enforced if one party does not deliver. It sets out what happens if a supply is defective, relying on the consumer guarantee framework in the Australian Consumer Law. And it prevents future disputes about what was agreed, which are particularly common in informal barter arrangements.
Without a written agreement, barter transactions can lead to disputes about value, timing, scope of the exchange, and tax obligations. A well-drafted agreement protects both parties and demonstrates to the ATO that the arrangement was conducted at arm's length.
When Do You Need a Barter Agreement (Australia)?
A Barter Agreement is needed whenever two Australian businesses or individuals agree to exchange goods or services without money as the primary consideration. Written agreements are especially important in the following situations.
When the exchange involves services rather than physical goods, because services are harder to verify after the fact. A written agreement records the scope and standard of services each party must deliver, avoiding later disagreements about whether obligations were met.
When both parties are GST-registered businesses. In this case, both parties have obligations to issue tax invoices and account for GST. A written agreement documenting the agreed market values creates a contemporaneous record that supports accurate GST reporting and input tax credit claims.
When the values of the two supplies are not equal and a cash top-up payment is required. The agreement documents the valuation of each supply and the amount of the balancing payment, which also has GST implications.
When the exchange will occur over time — for example, Party A provides services this month and Party B will reciprocate next month. Without a written agreement, the party that delivers first has no legal protection if the other party fails to perform.
When confidentiality matters — for example, two competitors in the same industry are undertaking a contra deal. A written agreement can include a confidentiality clause preventing either party from disclosing the terms of the arrangement.
What to Include in Your Barter Agreement (Australia)
A legally effective Australian Barter Agreement must include a number of key elements.
Identification of the parties: Full legal names and ABNs of both parties. ABNs are essential for GST compliance. If one party does not provide an ABN, the other may be required to withhold 47% of the payment value under the Pay As You Go (PAYG) withholding rules in the Taxation Administration Act 1953 (Cth).
Detailed description of each party's supply: The more specific, the better. For goods, include quantity, specifications, condition, and delivery location. For services, include the scope of work, number of hours or deliverables, and performance standards. Vague descriptions are the most common source of barter disputes.
Agreed values: Each party's supply must be given an agreed market value in Australian dollars. This value is used to calculate GST liability and to report the barter income in each party's tax return. The value should reflect what each supply would fetch in an arm's length cash transaction.
Delivery dates: Specific dates by which each party must deliver their supply. Time is of the essence where specified. Include what happens if a party cannot meet their date.
GST clause: A clear statement that both supplies are taxable supplies under the GST Act, that GST is payable at 10% of the GST-exclusive value, and that each party must issue a tax invoice. This is essential for both parties to correctly manage their BAS obligations.
Quality and warranties: Reference to the Australian Consumer Law guarantees that apply to the supply of goods and services. Neither party can exclude ACL consumer guarantees in a B2C context.
Remedies for non-performance: What each party can do if the other fails to deliver — suspension of obligations, termination, and compensation for direct loss.
Governing law: The Australian state or territory whose law governs the agreement.

Memorandum of Understanding (Australia)
Create an Australian Memorandum of Understanding (MOU) that correctly reflects the legal framework established by the High Court of Australia in Masters v Cameron (1954) 91 CLR 353. Covers the three categories of preliminary agreement (immediately binding, binding as to process, and non-binding/subject to contract), non-binding key commercial terms, good faith negotiation obligations following Coal Cliff Collieries Pty Ltd v Sijehama Pty Ltd (1991) 24 NSWLR 1, binding exclusivity periods, binding confidentiality obligations, no partnership disclaimer, costs allocation, long stop date, governing law, and jurisdiction. Suitable for commercial transactions, government-industry collaborations, joint ventures, licensing arrangements, and other Australian business negotiations requiring a preliminary document before a formal agreement is signed. A Memorandum of Understanding (MOU) is a preliminary document used across Australian commercial, government, and not-for-profit sectors to record the parties' mutual understanding and intention to collaborate, negotiate, or transact — before the negotiation of a comprehensive formal agreement is complete. In Australian commercial practice, the MOU bridges the gap between initial discussions and the execution of a binding contract, providing a written record of what has been agreed in principle and signalling the parties' commitment to progressing the transaction. The most important legal principle governing Australian MOUs is the three-category framework established by the High Court of Australia in Masters v Cameron (1954) 91 CLR 353. In that case, the High Court identified three distinct categories of preliminary agreement: (1) the first category, where the parties are immediately and fully bound by the document, even though a formal agreement is to be prepared later — the formal document is merely a record of what has already been agreed; (2) the second category, where the parties are immediately bound but anticipate that their obligations will be varied or supplemented when the formal document is executed; and (3) the third category, where the parties do not intend to be legally bound until the formal written agreement is duly executed — this is the 'subject to formal agreement' or 'subject to contract' category. A fourth category, recognised by the NSW Court of Appeal in GR Securities Pty Ltd v Baulkham Hills Private Hospital Pty Ltd (1986) 40 NSWLR 631 and confirmed in subsequent cases, is an agreement to negotiate in good faith — which is binding as to the negotiation process but does not compel the parties to reach agreement. For most commercial transactions in Australia, the third category of Masters v Cameron is the most appropriate framework for an MOU: the parties record their understanding and intentions without creating a binding obligation to complete the transaction. This allows the parties to withdraw from the transaction if the formal negotiations fail, without exposing themselves to damages claims from the other party. However, even a 'non-binding' MOU routinely includes certain binding ancillary provisions. The most important of these are: the exclusivity clause (which prevents either party from negotiating a competing transaction with a third party during the negotiation period); the confidentiality clause (which protects information shared during the due diligence and negotiation process); the costs clause (which specifies who bears the parties' legal and advisory costs if the transaction does not proceed); and the governing law clause (which specifies the applicable Australian state or territory law). These binding provisions can be enforced by Australian courts independently of the non-binding commercial terms. The good faith negotiation obligation recognised in Coal Cliff Collieries Pty Ltd v Sijehama Pty Ltd (1991) 24 NSWLR 1 is another important feature of Australian MOU law. An express contractual obligation to negotiate in good faith is enforceable in Australian courts: it requires the parties to negotiate honestly, diligently, and without acting in a manner designed to undermine the other party's reasonable expectations — but it does not require either party to agree to terms they find commercially unacceptable. MOUs are used in a wide variety of Australian contexts: commercial transactions (mergers and acquisitions, joint ventures, distribution arrangements, licensing deals); government-industry collaboration (particularly in defence, infrastructure, and health); research and development collaboration between universities and industry; not-for-profit and philanthropic arrangements; and international business development where parties in different jurisdictions wish to record their collaborative intentions before committing to a full international agreement. Parties should obtain independent legal advice before executing an MOU, particularly regarding the classification of the MOU under the Masters v Cameron framework, the enforceability of the binding ancillary provisions, and the interaction between the MOU and any existing agreements between the parties.
