A developer walking away from signed contracts is bad enough. What should worry builders more is how little stands in the way of it happening again.
Last week, national developer Wel.Co cancelled 101 signed contracts at its Springwood estate at Gawler East, north of Adelaide.
Seventy-five were buyers who had bought retail lots. Twenty-six were builders who held contracts for lots of their own.
The company pointed to changes in planning and infrastructure across the broader growth area. It said a road once expected to operate locally is now planned as a major distributor road carrying much more traffic, and that this fundamentally changed the living environment for adjoining homes. On that basis, it said stages eight and nine could no longer be delivered as buyers had contracted. Wel.Co said the issue was isolated to those two stages and that the rest of its portfolio was progressing as planned.
For the people holding those contracts, the reason barely matters. The outcome is the same. They signed in good faith, they made plans around those blocks, and now they are starting again.
Why builders should care, not just buyers
It is easy to file this under “buyer story” and move on. That would be a mistake.
Twenty-six of the cancelled contracts were builders. Think about what that means in practice. You win the work, you price it, and you build a chunk of your forward pipeline around a specific block in a specific estate. Maybe you knock back other jobs to hold capacity. Then the land underneath the whole arrangement disappears.
You are not just out one job. You are out the time, the quoting, the client relationship, and the slot in your schedule you can no longer fill at short notice.
This is the quiet risk in building your pipeline around large land releases. The blocks are only as certain as the developer’s willingness to deliver them, and across most of the country there is surprisingly little forcing that willingness. Solid off-the-plan contracts help, but they only go as far as the law behind them.
Where the two sides land
The accounts do not line up, and that gap is the story.
Wel.Co’s position is that it was responding to planning and infrastructure changes it did not control. It says a local road was rescoped into a major distributor route, that this altered the stages materially, and that the affected lots could no longer be delivered as contracted. Framed that way, it reads as a developer caught by a decision made above it, which does happen.
The Town of Gawler tells it differently. The council says that across all its engagement, and the state’s, on road design and infrastructure, Wel.Co never signalled that the changes could end in cancelled contracts. The mayor called the outcome deeply disappointing for families who thought they were about to start building.
The state has taken the council’s side of that account. Its cabinet has authorised the Commissioner for Business Services to actively examine all legal options to hold the company to account. The planning minister said the cancellations came without real justification and that nothing the state did on infrastructure would have forced them. The premier said the clauses that let developers walk away should be examined, and that the government would look at legislative options unless the contracts were reinstated.
Whether the planning changes genuinely made those stages undeliverable, or whether they could have been absorbed without tearing up contracts, is the question the commissioner’s examination will have to work through. From the outside, with the parties disagreeing on the facts, it is not one to call early. What is already clear is the mechanism that made the cancellations possible, and that part is worth builders’ attention regardless of how the fault question resolves.
The mechanism, and why the state you build in decides your exposure
You already know how a sunset clause is supposed to work: it lets either side out if the plan is not registered by the agreed date, and it exists so a buyer is not trapped in a project that never completes. You also know how it gets used the other way, a project allowed to drift toward the date so the developer can rescind, return the deposit, and re-release the same land at today’s price. That is the play the law in the eastern states has spent the last decade trying to shut down.
New South Wales moved on it in 2015, Victoria in 2019, Queensland in November 2023. In all three, a developer generally cannot rescind an off-the-plan land contract under a sunset clause without the buyer’s written consent or a court order, and the court has to be satisfied the cancellation is just and equitable. The onus sits on the developer to justify the exit.
South Australia has not gone that far yet. The state did overhaul its building laws through the Building and Construction Industry Review, and part of that package became law in January 2026. But that Act dealt with penalties, offences and enforcement. New rules for the use of sunset clauses in off-the-plan sales were flagged as a further change under the same review, and they are not yet on the books.
Which is why, when 101 contracts were cancelled last week, the government’s response was to talk about examining options rather than pointing to a protection already in force.
The lesson for builders is blunt. Your exposure when a developer walks away is not really about the developer. It is about the postcode. The same contract, the same cancellation, the same reasons would land very differently in Sydney, Melbourne or Brisbane than it does in Gawler right now, because in those states the developer would have to justify itself to a court. In South Australia, at the moment, it does not. If it came to a fight, that is the difference between a building dispute you can run and one you cannot.
Will we see more of this?
Probably, and for reasons that have nothing to do with any one company. Growth-area infrastructure is being redesigned all over the country as governments chase housing supply pressure and their own targets. Holding costs are high. Land values in many corridors have moved. Every one of those pressures gives a developer a reason, or a cover, to reset a deal. The gap between the states that have closed the door on that and the states that have not is now wide and obvious.
The Springwood cancellations may end up being exactly what Wel.Co says they are: a genuine casualty of planning changes outside its control. The government’s examination will test that. But whatever the finding, the episode has exposed something bigger than one estate. It has shown builders and buyers in one state that their contracts rest on ground that three other states decided, years ago, needed shoring up.
If you are building in South Australia, that is worth knowing before you next tie your pipeline to a land release. Read the sunset clause. Understand who can pull the pin, and when. Because until the law changes, the answer is: more easily than you would like.
Frequently asked questions
Yes. If the contract contains a sunset clause and its conditions are met, a developer can rescind. South Australia has not yet enacted the kind of restriction that applies in the eastern states, so a developer here is not currently required to get the buyer’s consent or a court’s approval first. The state government has said it will look at legislative options, but as things stand the contract terms and the sunset clause govern. That is why the Springwood cancellations were possible.
It is the provision that sets a deadline, the sunset date, by which the plan of subdivision has to be registered or the project completed. If that date passes without the milestone being met, either party can rescind. It exists so a buyer is not locked into a project that never finishes. The catch is that a developer can also use it to exit, and in a rising market that exit can be worth more to them than the sale.
Generally yes. When a contract is rescinded under a sunset clause, the deposit is refunded, sometimes with interest depending on the terms. But the money is the smallest part of the loss. The buyer walks away without the block, without the time spent waiting, and without any capital growth they would have captured had they bought elsewhere. In a market that has moved, a refunded deposit does not buy back the same position.
Three eastern states have moved: New South Wales in 2015, Victoria in 2019, and Queensland in 2023 for land contracts. In each, a developer generally cannot rescind under a sunset clause without the buyer’s written consent or a Supreme Court order, and the court has to be satisfied the cancellation is just and equitable. The onus sits on the developer to justify the exit. The ACT introduced similar protections in 2021. South Australia has flagged reform through its building review but has not yet passed it.
They are in the same position as the buyers, with a business cost on top. A builder who had contracted a lot loses the job, the quoting and pricing work already sunk into it, the client relationship built around it, and the slot in the schedule set aside to deliver it, which is hard to refill at short notice. At Springwood, 26 of the 101 cancelled contracts were builders. That is the part of these stories that usually goes unreported, and it is why a cancellation like this is a pipeline risk, not just a buyer’s misfortune.
