Let me ask you something: If you were about to invest hundreds of thousands of dollars into a build, in a cyclone-rated, freight-dependent, remote market… would you want the price in your build contract based on assumptions?
Most people come to Broome because the numbers make sense. The rent’s strong, the demand’s there, you run it through a spreadsheet and it stacks up.
By the time you’re sitting down with a build contract, you’ve already decided you’re doing it. You’re not weighing up the market anymore. You’re thinking, “Alright, let’s get this moving.”
And that’s usually where I say, “Hang on a minute.”
Because most of the budget problems we see up here don’t come from the market doing something unexpected. They come from things that weren’t fully sorted out before the contract was signed.
If I had to give you one bit of advice before you put pen to paper, it’s this:
Choose everything you can BEFORE you sign.
Because This Is Where It Usually Starts
You’ll see two terms in most contracts: prime cost items and provisional sums.
A prime cost item is an allowance for something you’ll choose later, like tiles, tapware or appliances. The builder puts in a dollar figure as a placeholder. If you pick something that costs more than that allowance, you pay the difference.
A provisional sum is slightly different. It’s an estimate for work where the exact cost isn’t known yet, like site works, drainage or certain structural elements. If the actual cost comes in higher than estimated, that difference is added to the contract.
There’s nothing wrong with that in principle. It’s just a way to keep the process moving while decisions are still being made.
The key thing to understand is that both can move. And if they move up, so does your final price.
In Broome, that could mean thousands added to the price you thought you were getting:
- Freight isn’t cheap
- We’re in a cyclone zone, so structural requirements are stricter
- Certain materials need to be installed in very specific ways
- And there aren’t endless suppliers to fall back on if something changes
We recently worked with an interstate investor who signed with a few allowances still open. Nothing unusual. Once the final selections were made and engineering ran its checks, the gap between what was allowed for and what was required came in at just over $18,000.
No one did anything wrong. The contract did exactly what it said it would.
But decisions that felt minor at the start became expensive once the job was underway.
Why Rushing a Build Contract Costs More
I get it. Once you’ve decided to build, you want momentum and to see progress. Builders want the same thing, because getting to contract means we can book trades, order materials and lock things in.
But moving fast and being ready aren’t the same thing.
If you haven’t picked your finishes, confirmed your fixtures, and lined that up with engineering before signing, then the price on the page is still based on assumptions.
And assumptions are fine… until they’re not.
In a place like Broome, changes once the build has started tend to carry more weight. Things like tie-down systems, waterproofing requirements and compliance checks aren’t surface-level adjustments – they’re structural. And when those elements shift, it’s not just the cost that moves. Timing can too.
The smoothest builds we see tend to have a few things in common:
- Selections are locked in before the contract is signed.
- Engineering has been checked against the actual materials being used.
- Allowances are realistic, not optimistic.
- Everyone knows exactly what’s being built before we break ground.
That doesn’t mean nothing unexpected ever happens. It just means you’ve taken out most of the avoidable stuff.
Broome Isn’t Forgiving Of “We’ll Sort That Out Later”
This is a great market. The returns are there for a reason. But it’s also remote. Freight takes time, suppliers are limited, and compliance isn’t flexible.
If something changes once the build’s underway, you don’t just duck down the road to fix it. It affects sequencing. It affects trades. Sometimes it affects delivery windows.
That’s why unresolved decisions carry more weight up here than they might in a bigger city.
When you choose everything upfront:
- The allowances turn into real numbers.
- Engineering lines up with what’s actually being installed.
- Variations drop dramatically.
- You’re working with solid figures, not “we’ll see.”
It’s not about being overly cautious. It’s just about being properly prepared.
Broome’s a strong place to invest. The issue isn’t building here, but assuming it works the same way as Perth or any other metro market. It doesn’t. And that difference matters.
If you’re close to signing, just pause for a second and ask yourself:
- Have I actually chosen my finishes?
- Are the allowances in this contract realistic for what I want?
- Has engineering been looked at properly against those selections?
If the answer’s “not yet,” that’s fine. It just means there’s another step to take before locking it in.
Of course, there’s a lot more to building in Broome and doing it within budget than what we’ve covered here today. That’s why we’ve put together this free guide:
Inside, we cover:
- Why a builder’s reputation tells you nothing about whether they can actually deliver your project on time in a remote market
- What “remote” really means for your timeline and why your 24-week contract might be optimistic
- Why “been here for 20 years” doesn’t automatically mean they have the infrastructure to keep your project moving when things get difficult
- How a locked-in contract can still cost you significantly if your builder doesn’t have the financial depth to sustain it
- Why the cheapest builder is rarely the smartest choice when you need someone who’ll still be there in year five
In remote construction, the most expensive mistakes don’t start on site. They start on paper with assumptions that later turn into variations.
We’ve seen that add $15,000 or more to projects that otherwise ran smoothly.
If you’re about to commit to a build in Broome, it makes sense to understand how to prevent that before signing your build contract.

To better understand the standards, risks, and expectations involved in a Remote-Build project, it’s worth reviewing guidance from industry bodies like Master Builders Australia and the Association of Professional Builders before committing to your next investment.
Broome build contract: your questions answered
What should you check before signing a Broome build contract?
Before signing a Broome build contract, confirm three things: your finishes and fixtures are chosen rather than left as allowances, the allowances that remain are realistic rather than optimistic, and engineering has been checked against the actual materials being used. Locking these in before you sign is what stops assumptions turning into costly variations later.
What are prime cost items and provisional sums in a building contract?
A prime cost item is an allowance for something you choose later, such as tiles, tapware or appliances; if your choice costs more than the allowance, you pay the difference. A provisional sum is an estimate for work whose exact cost is not yet known, such as site works or drainage. Both can move up, and if they do, so does your final price.
Why can building allowances cost more in Broome specifically?
Broome is remote and cyclone-rated, so freight is expensive, structural requirements are stricter, some materials must be installed in specific ways, and suppliers are limited. Once final selections and engineering are confirmed, the gap between what was allowed for and what is required can add thousands, a risk we cover in our guide to remote build realities in Broome. One interstate investor saw that gap reach just over $18,000.
Why does rushing to sign a build contract cost more?
Moving fast and being ready are not the same thing. If finishes are not picked, fixtures not confirmed and engineering not aligned before signing, the price on the page is still based on assumptions. In Broome, mid-build changes to structural elements like tie-downs, waterproofing and compliance affect both cost and timing, so unresolved decisions carry more weight than they would in a metro market.
How do you avoid variations on a remote build?
Choose everything upfront. When selections are locked in before the contract is signed, allowances become real numbers, engineering lines up with what is actually installed, and variations drop dramatically. It is not about being overly cautious, just properly prepared, so you work with solid figures rather than we will see.
