Cash Rate Hits 4.60% — Here’s What That Adds to Your First Home
The RBA lifted the cash rate to 4.60% on 29 September, its fourth hike this year and the highest level since 2011. For first-home buyers, that adds about $113 a month on an average $731,000 loan, per Money magazine. It’s a heavy hit for anyone planning to build.
But repayments are only half the bill. Most buyers obsess over the rate and ignore the build quote, yet house construction prices rose 5.9% over the year to June, per the ABS. Here’s the full cost, and how to plan around it before you sign.
What Has the RBA Actually Done to Your Repayments?
Four hikes since February have lifted the cash rate from 3.60% to 4.60%, per the RBA. That’s 100 basis points in eight months, a pace few buyers budgeted for. Lenders typically pass these rises on to variable loans, so your monthly repayments climb even though your income hasn’t moved.
Don’t bank on relief soon. The RBA says it will lift rates again if needed, and ANZ is the only major bank pricing another hike in November. The next RBA meeting lands on 3 November. Plan around the rate you can afford, not the cut you’re hoping for.
How Hard Are Building Costs Hitting a New Home?
ABS data shows house construction prices rose 5.9% over the year to June 2026, the biggest annual jump since mid-2023, on a $500,000 build quote, which adds roughly $29,500. Materials grab the headlines, but scarce trades are the real handbrake on delivery times.
Every idle month costs you rent and interest on progress payments, long before the keys arrive. Rising building costs in Australia also stack on top of higher borrowing costs, and the two feed each other. That’s why a build that looked affordable in January can look stretched by October.

Where Is the Extra Money Actually Landing?
Watch these five pressure points:
- Higher monthly repayments from four hikes in 2026
- Build price growth lifting your final quote
- Interest on construction progress payments
- Rent while delays push back handover
- A contingency buffer that 3% no longer covers
Is Waiting Really the Safer Play?
Most buyers get this backward, as they wait for rates to fall and assume the build quote will sit still. It won’t. Building construction prices rose 1.0% in the March quarter, driven by houses, then house construction jumped another 2.0% in June, per the ABS. Waiting isn’t a strategy. It’s a bet.
Meanwhile, investors and owner-occupiers compete for the same builders, trades and house-and-land stock, and waiting hands them first pick. Don’t chase the market, though. Stress-test your repayments at 4.85%, one more quarter-point hike than today, add a proper buffer, and move only if the numbers still hold.
What Should You Lock In Before the Next RBA Meeting?
- A fixed-price build contract, signed before further rises flow through
- A contingency of 10% of build cost, not 3%
- A builder with a verifiable delivery history, not the cheapest quote
- Repayments tested at 4.85%, not just today’s rate
- Finance pre-approval checked against current rates
How Much Should You Borrow While Rates Keep Climbing?
Most buyers borrow what the bank offers, and that’s a mistake. A lender’s maximum tells you what it’s willing to risk, not what you can live with. Work backward from a comfortable monthly repayment at 4.85%, then let that number set your budget.
Keep spare cash after repayments, because build delays and surprise extras never arrive on schedule. If your plan only works at the top of your borrowing range, shrink the plan, not the buffer.
Is a Turnkey House-and-Land Package Safer Right Now?
A turnkey package bundles land and build under one contract, so you know the full price upfront. That certainty carries real value while construction prices keep rising. It also gives you one contract to read instead of several.
Certainty isn’t automatic, though. Check the inclusions line by line, confirm what sits outside the price, and test the builder’s delivery record. A cheap package with thin inclusions simply moves the blowout to after handover.
The Bottom Line: A 4.60% Cash Rate Rewards Discipline, Not Timing
A 4.60% cash rate costs you every month, and rising build prices cost you before you collect the keys. Neither justifies panic. Both demand proper numbers, a real buffer, and a refusal to back any plan that only works if rates fall. Buy with discipline, build with a cushion, and treat every optimistic forecast as a bonus rather than a plan.

FAQs:
How much contingency should I budget on a new build?
Aim for 10% of total build cost, not the old 3%. At today’s rates, one supplier increase or trade delay can wreck a thin buffer. A bigger cushion also stops you scrambling for extra finance mid-build.
What does a fixed-price contract actually protect me from?
It protects you from cost rises after you sign, not before. Builders price expected increases into quotes, so signing early beats signing late. Ask your builder exactly what the contract excludes before you sign.
How do I stress-test my repayments for another hike?
Add 0.25 to 0.50 percentage points to your loan rate and check you still cover repayments comfortably. Use the Mortgage Repayment Calculator on our website to run it. Do it before you sign, not after, so the answer shapes the decision.
Which build costs do buyers forget to budget for?
Holding costs catch people out: interest on progress payments and rent during delays. Extras outside the base contract add up too, so ask for every inclusion in writing. A written list of inclusions prevents most nasty surprises.
