Sunset Clause: The Real Risk in 2026, State by State

August 21, 2026 4 Min Read

A sunset clause sounds like fine print, but a 2025 court case shows developers still misuse it in a rising market. Here’s what it actually means, and why protection still varies enormously depending on your state.

Quick Answer: Sunset Clause

A sunset clause is a deadline in an off-the-plan property contract. If the developer hasn’t finished and settled the sale by that date, either side can usually cancel. The buyer then gets their deposit back. The risk is a developer cancelling on purpose in a rising market, then reselling at a higher price. NSW and Victoria now require developer consent or a court order to do this. Queensland only protects land contracts, not apartments. A 2025 court case proves this still happens, even where laws exist.

1. What a Sunset Clause Actually Does

It sets a hard deadline for settlement. So if a developer hasn’t finished the build by that date, either side can usually cancel the contract.
Either party can normally trigger it. But in practice, developers have the most reason to use it, since delays and rising prices work in their favour.
A triggered clause usually means a full deposit refund. So on paper, it looks like a fair, low-risk safety net for the buyer.
The real risk shows up when a developer wants out. A rising property market gives a developer a real financial reason to let the deadline pass on purpose.

2. The Case That Proves This Still Happens

A court ordered a Queensland developer to repay $6.1 million in 2025. The court found the developer illegally invoked a sunset clause on two Brisbane penthouses.
The developer had bought the units back at $4.2 million. It then resold them for around $10 million after cancelling the original buyer’s contract.
This happened well after most reform laws were introduced. So it’s clear evidence the problem isn’t fully solved just because legislation exists.
Buyers in some states have far less protection than others. That’s exactly why the state you’re buying in matters so much here.

3. Protection Varies a Lot by State

NSW and Victoria offer the strongest protection. A developer generally needs buyer consent or a court order before cancelling under a sunset clause in either state.
The ACT uses a notice-based system instead. So a developer must give 28 days’ written notice and get buyer consent, and must cover related costs too.
Queensland only protects land contracts, not apartments. This is the gap the 2025 court case exposed, and the Queensland government is still reviewing it.
WA, Tasmania, and the Northern Territory have few extra rules. So buyers there rely mostly on the general terms of their contract, not dedicated laws.

4. What to Do If You’re Worried About One

Read the sunset date before you sign, not after. So check exactly when it falls, and how far away that is from a realistic finish date.
Ask your solicitor about your specific state’s rules. Since protection differs a lot between states, generic advice isn’t always right for your contract.
Watch for construction delays as an early warning sign. A project running behind schedule is the clearest sign a sunset clause might actually get triggered.
Get legal advice well before the deadline, not after it passes. So you still have options if a developer signals they might rely on the clause.

FAQ: Sunset Clause

What is a sunset clause in a property contract?
It’s a deadline for settling an off-the-plan purchase. If it passes without settlement, either party can usually cancel and the buyer gets their deposit back.

Can a developer use a sunset clause to cancel my contract unfairly?
Yes, this has happened. In a 2025 Queensland case, a court ordered a developer to repay $6.1 million after it illegally cancelled and resold at a higher price.

Is a sunset clause different by state in Australia?
Yes. NSW and Victoria require consent or a court order to rescind. The ACT uses a notice system. Queensland only protects land contracts, not apartments.

Do I get my deposit back if a sunset clause is triggered?
Generally yes, if the clause is triggered legitimately. That’s the whole point of the clause as a buyer safeguard.

Is there a sunset clause in home loans, or only in property contracts?
It’s almost always a property contract term, specifically in off-the-plan purchases. It isn’t a standard home loan feature.
