Australia’s property market is once again making headlines, with rising house prices Australia showing record-breaking growth as some suburbs jump by hundreds of thousands of dollars in just three months. According to the Domain House Price Report (Q2, 2025), suburbs like Cammeray in Sydney’s Lower North Shore surged by an eye-watering $562,000 between March and June, pushing its median house price into the $3.3 million range. Other suburbs in Sydney, Brisbane, and Perth also broke new price barriers, with some areas crossing the $1 million and $2 million milestones for the first time.
But what does this mean for everyday Australians—especially homeowners, buyers, and property investors? Let’s break it down from a financial and tax planning perspective.
Why Prices Are Rising So Quickly
Local real estate agents point to a mix of low supply, strong demand, and lifestyle-driven moves as the key drivers. For example, Cammeray remains exempt from high-density rezoning, keeping housing stock limited. In Sans Souci, waterside living is drawing high-end buyers priced out of the eastern suburbs. Meanwhile, in Brisbane’s Banyo, affordability relative to nearby suburbs is creating fierce competition.
This rapid growth is good news for current homeowners, but for buyers, it creates new challenges in affordability, lending, and tax obligations.
The Tax and Accounting Side of a Property Boom
When property prices soar, it’s not just about market value—it flows directly into your financial strategy:
1. Capital Gains Tax (CGT) Considerations
If you’re an investor thinking of selling, a sharp increase in property value means a higher potential capital gain. The ATO requires you to report this gain, although discounts (like the 50% CGT discount for properties held over 12 months) may apply. Planning the timing of your sale can make a big difference to your after-tax profit.
2. Negative Gearing and Rental Deductions
For buyers entering million-dollar-plus suburbs, loan repayments are much higher. Some investors use negative gearing strategies, offsetting property losses against other income. You can also claim legitimate rental deductions—repairs, property management fees, insurance, and even depreciation on fittings. These claims reduce taxable income, helping to soften the financial impact of rising property costs.
3. Stamp Duty and Holding Costs
As property values rise, so do stamp duty liabilities. For example, purchasing a $2 million home in NSW could attract well over $90,000 in upfront stamp duty. This is where strategic advice becomes crucial—especially for families or first-home buyers weighing the long-term cost of entering a rapidly rising suburb.
Relatable Example: Upgrading in Today’s Market
Let’s say a family in Russell Lea purchased a home for $2.9 million earlier this year. Within three months, Domain reports the suburb’s median price jumped by nearly $280,000. On paper, that family is now sitting on a significant equity gain.
But if they were to sell and upgrade to a $4 million property in Killara (another fast-rising suburb), they would face:
- Higher stamp duty costs (potentially exceeding $200,000)
- A larger mortgage and higher interest repayments
- New land tax liabilities, depending on the property type
This is where smart tax planning—like exploring loan structuring, timing the sale, or leveraging deductions—helps families make the most of their property gains without being blindsided by hidden costs.
What Buyers and Investors Can Do Right Now
- Get professional advice early – Before bidding at auction, understand the stamp duty, CGT implications (if you’re selling), and how loan structuring affects your long-term tax position.
- Reassess borrowing capacity – With million-dollar suburbs growing, buyers may need to revisit lending options. Mortgage stress is a real risk if interest rates shift again.
- Maximise deductions – Whether you’re holding, renting, or renovating, every eligible deduction—like depreciation schedules—improves your net return.
- Think long term – Just because prices are surging now doesn’t mean the trend will last forever. A sound investment strategy should account for market cycles, not just the short-term highs.
