Before we get lost in the $$$, let’s break it down. Stamp duty (aka transfer duty) is basically a “welcome to the neighbourhood” tax from the government. It’s calculated based on your property value and where exactly you’re building your vision.
The good news? There are some remarkable savings on offer:
- In WA: First home buyers can score major concessions on vacant land, depending on value and eligibility.
- In SA: If you’re an eligible first home buyer building brand new, you’ll pay no stamp duty at all. Zero. Zilch. Nada.
Let’s unpack:
| Vacant Land (part of a house & land package) | Duty Payable | |
| Western Australia | South Australia | |
| $0-$350,000 | No duty payable | No duty payable |
| $350,001-$450,000 | You’ll pay $15.39 for every $100 (or part thereof) above $350,000 | |
| $450,001+ | Standard residential stamp duty rates apply | |

How is stamp duty calculated in Australia?
Think of it like a ladder. Instead of one flat rate, the state looks at your purchase price and applies different tax brackets as you climb higher.
Property value and how it impacts you
The price tag is the big driver here. As the value climbs, you move into higher brackets where a larger percentage is taxed. For house and land packages, the value used is generally the land’s value at the time of signing, not the finished home. This can slash your upfront costs.
Why rates differ between states and territories
Each state decides its own thresholds, rates and concession schemes based on local housing conditions.
That’s why a buyer in WA might pay a completely different amount to someone in SA for a similar property, and why your budget needs to be 100% local. What works in Perth might look totally different in Adelaide.
Where first home buyer concessions come in
Concessions are designed to help you get into the market without the massive headaches. These perks tend to favour new builds or vacant land. The way house and land purchases are structured makes it much easier to score these savings.
Do first home buyers pay stamp duty?
The answer? Sometimes yes, sometimes no. It all depends on your eligibility, the type of property you’re eyeing and the final price tag.
For some, stamp duty gets reduced. For others, it’s completely gone. If your purchase falls outside the criteria, though, you’ll be paying the standard rate like everyone else.
How eligibility is assessed
It’s not just an automatic “yes”. You’ve got to be a genuine first-home buyer who hasn’t owned property in Australia before. Plus, the home needs to be your actual residence, not an investment property.
There are also price caps that vary by state. If your price tag sits even a dollar above the threshold, you might lose the exemption or only get a partial discount. Precision is key!
When and how stamp duty is paid
Stamp duty isn’t something you’ve got to worry about the second you make an offer. It comes into play much closer to settlement, when the keys are almost in sight!
Part of the settlement, not the deposit
When you sign on the dotted line, you’ll pay a deposit first. Stamp duty is a totally separate cost and is typically paid at or just before settlement. Your conveyancer will ensure the funds arrive on time so your move-in date stays on track.
What affects how much stamp duty you pay?
Like we said before, there’s no single “magic number” that applies to everyone. There are a few key factors that decide your total bill:
Property type (new vs established)
Building new is much kinder to your bank account. You’re usually only taxed on the land value, whereas buying established means paying duty on the whole property.
First home buyer status
First-timers get the perks. If this isn’t your first home, you’ll likely be hit with the standard rates, meaning you’ll need a bit more stashed away before you get started.
Location and state-based rules
Each state plays by its own rules. Because stamp duty works on a sliding scale, knowing your local thresholds is the best way to make sure you’re making your mark without any surprises.
Final thoughts
At the end of the day, stamp duty isn’t just another bill. It’s the final hurdle between you and your own front door. While the numbers can feel like a lot to juggle, knowing exactly where you stand with concessions is your biggest advantage. It’s the difference between a budget that actually works and a last-minute scramble.
The best move? Don’t guess the math.
Every situation is a little different, and the state thresholds go down to the dollar. Get your plan locked in early, double-check your eligibility and make sure your budget is set up for success from day one.
You’ve done the hard work; make sure getting over the finish line is smooth too.
