Overview
Buying a newly subdivided lot in Australia involves one of two fundamentally different contract types depending on whether the new title has already been registered. Understanding which type of contract applies to your purchase — and what the key clauses mean — is essential before you sign anything. Errors at contract stage are among the most common and costly mistakes in property transactions, and they're almost always avoidable with proper legal advice upfront.
This guide explains the structure of both contract types, the clauses that matter most in a subdivision context, and the legislative protections that now apply to off-the-plan buyers across Australia.
Titled Lots vs Off-the-Plan Contracts
The first question to establish when purchasing a subdivided lot is whether the title has already been issued:
Already-Titled Lots
If the plan of subdivision has been registered and new individual titles have been issued, the sale proceeds under a standard contract of sale — the same type used for any existing residential property. The lot already exists as a legal entity. Settlement typically occurs 30–90 days after exchange, and the buyer takes an immediately defined piece of land with a registered title.
Off-the-Plan (OTP) Lots
If the plan of subdivision has not yet been registered — meaning the lot you're buying exists only on a proposed plan — the sale occurs "off the plan." The contract is signed now, but settlement cannot occur until the new title is created and registered. This may be weeks, months, or in some cases years away. Off-the-plan contracts carry additional risk and are subject to specific legislative protections not present in standard contracts.
Why Off-the-Plan Contracts Are Different
Because the land doesn't legally exist yet at the time of signing, off-the-plan contracts must describe the lot by reference to a proposed plan rather than a registered title. Everything from the lot boundaries to easements, covenants, and body corporate arrangements is "proposed" — and subject to change. This is why the law imposes additional disclosure obligations on vendors and additional protections for buyers.
Key Clauses Every Buyer Must Understand
Whether buying a titled or off-the-plan lot, certain contract clauses warrant careful review before signing:
Finance Condition
A finance condition gives the buyer a specified period (typically 14–21 days) to obtain formal loan approval. If unconditional approval isn't obtained in time, the buyer can rescind and recover their deposit. Never waive a finance condition on an off-the-plan lot — obtaining finance approval for a yet-to-be-titled property can be complex.
Settlement Date and Trigger Events
For off-the-plan contracts, settlement is triggered by a specific event — usually the registration of the plan of subdivision and the issue of the new title — rather than a fixed calendar date. The contract should specify how and when the vendor notifies the buyer that settlement is due, and how many days' notice the buyer receives before settlement must occur (typically 14 days).
Sunset Clause
A sunset clause sets a deadline by which the plan of subdivision must be registered. If the deadline passes without registration, either party may have rights to rescind — subject to significant legislative restrictions on the vendor's ability to use the clause. This is one of the most important clauses in any off-the-plan contract (see below).
Default Interest
If settlement is delayed due to the buyer's failure (e.g., finance falls through at settlement), the vendor is typically entitled to charge default interest on the outstanding balance — commonly at a rate of 2–4% above the standard variable rate. This can be extremely costly on a large purchase price.
Inclusions and Schedule of Finishes
For lots that include a dwelling to be constructed, the contract must specify exactly what is included — fixtures, fittings, landscaping, driveways. Vague descriptions like "as per plan" without a detailed schedule leave buyers exposed to disappointment at handover. Ensure all inclusions are listed specifically and in writing.
GST and the Margin Scheme
The sale of a new residential lot is subject to GST. Vendors may elect to apply the margin scheme under the GST Act, which calculates GST on the margin (sale price minus acquisition cost) rather than the full price — potentially reducing the GST payable. Whether the margin scheme applies affects how the contract price is expressed and must be clearly stated. Always seek tax advice on GST treatment before signing.
Sunset Clauses: Developer and Buyer Rights
Sunset clauses have been the subject of significant legislative reform across Australia following cases where developers deliberately delayed plan registration to rescind contracts and resell at higher prices. The current position in key states:
| State | Legislation | Vendor Can Rescind Under Sunset If… | Buyer Rights |
|---|---|---|---|
| Victoria | Sale of Land Act 1962 s.9AE | Buyer gives written consent, OR Supreme Court orders it | Can rescind and recover deposit + up to 2% compensation |
| NSW | Conveyancing Act 1919 s.66ZL | Buyer gives written consent, OR Supreme Court orders it | Can rescind and recover deposit in full |
| Queensland | Property Law Act 2023 | Buyer gives written consent, OR court orders it | Deposit refunded; possible damages claim |
| WA | Sale of Land Act 1970 | Buyer gives written consent | Deposit refunded on rescission |
The practical effect is that developers can no longer use sunset clauses as a mechanism to opportunistically exit contracts when property prices rise. A developer wishing to rescind must either obtain the buyer's written agreement (which a buyer is under no obligation to give) or go to court — a costly and uncertain process.
How Deposits Are Held
In an off-the-plan contract, the deposit paid by the buyer must be held in a trust or controlled money account — it cannot be released to the developer until settlement occurs. This protection exists across all states and is designed to protect the buyer in the event of developer insolvency.
- Standard deposit: Typically 10% of the purchase price, though some developers accept 5% for off-the-plan lots.
- Deposit bond: Instead of cash, buyers can use a deposit bond — a guarantee from an insurance company substituting for the cash deposit. Developers must agree to accept this.
- Interest on trust deposits: Some states allow interest earned on a trust deposit to be paid to the buyer at settlement; others allow the vendor to retain it. Check the contract terms and relevant state legislation.
- Early release: Developers sometimes negotiate for early release of the deposit from trust (e.g., to fund construction costs). Buyers should be cautious about agreeing to early release, as it removes the trust account protection.
Material Changes to the Plan
Between contract exchange and plan registration, the plan of subdivision may change. A lot may be slightly smaller than originally shown; easements may be added; common property boundaries may shift. Most off-the-plan contracts allow the vendor to make minor changes without buyer consent. However, if a change is material — meaning it substantially affects the lot being purchased — the buyer typically has a right to rescind the contract.
What constitutes a material change is not always obvious and varies by state legislation and contract terms. Changes that are commonly considered material include:
- A reduction in lot area of more than a specified percentage (often 5%).
- The addition of a significant new easement over the lot that was not disclosed.
- A change to the position of the lot on the plan that alters its aspect, access, or amenity.
- A substantial reduction in the floor area of a dwelling included in the contract.
Cooling-Off Rights
Most Australian states provide a cooling-off period after signing a contract of sale, during which the buyer can rescind without being in default. Cooling-off rights apply differently by state:
| State | Cooling-Off Period | Penalty for Use | Applies to Auctions? |
|---|---|---|---|
| Victoria | 3 clear business days | 0.2% of purchase price | No |
| NSW | 5 business days | 0.25% of purchase price | No |
| Queensland | 5 business days | 0.25% of purchase price | No |
| Western Australia | 3 business days (residential only) | 0.2% of purchase price | No |
| South Australia | 2 clear business days | Nil | No |
Cooling-off rights can be waived by the buyer (typically in exchange for a vendor concession) or may not apply if the buyer was legally represented at exchange. In Victoria, if the buyer's solicitor or conveyancer provides a certificate of independent legal advice (known as a "section 3 certificate"), the cooling-off right does not apply.
Recent Legislative Buyer Protections
Australian property law has moved significantly in favour of off-the-plan buyers over the past decade. Key recent changes that buyers and their advisers should know about:
- NSW (2019 onwards): Expanded disclosure requirements for off-the-plan contracts, including mandatory disclosure of any restrictions on the use of the lot, proposed by-laws for strata or community title schemes, and a sunset date that must be reasonable having regard to the nature of the development.
- Victoria: The Sale of Land Act 1962 restricts developer sunset clause rescissions and provides buyers with up to 2% compensation where a developer attempts rescission and the court finds it was not in good faith.
- Queensland (1 August 2025): The Property Law Act 2023 introduced a comprehensive new seller disclosure scheme with much more rigorous disclosure requirements for all property sales, including off-the-plan lots.
Key Takeaways
- Off-the-plan contracts are significantly more complex than standard contracts — always obtain independent legal advice before signing.
- The sunset clause is the most critical clause for off-the-plan buyers — ensure it is set to a realistic date and understand the restrictions on the developer's ability to use it.
- Deposits must be held in a trust account and cannot be released to the developer until settlement.
- Material changes to the plan after exchange may give you a right to rescind — but the threshold varies by state.
- Cooling-off rights apply in most states but cannot be exercised without forfeiting a penalty — they are a last resort, not a substitute for due diligence.
