Australia’s property boom shows no signs of slowing—latest PropTrack data reveals 202 suburbs have seen median house prices surge by at least $100,000 since late 2024. These gains span across both prestigious and affordable regions, proving it’s not just elite neighbourhoods cashing in.
Major Market Movers
- Sydney leads, with 65 suburbs posting six-figure rises. The gold-standard is Sylvania Waters, where prices soared nearly $597,000 (up 19%), and pricey eastern suburbs like Greenwich (+$532K), Cammeray (+$450K), South Coogee (+$400K) also topping the list.
- Brisbane, Perth & Adelaide experienced strong growth in more affordable enclaves—notably Surfers Paradise (+$450K), Ascot (+$310K), Dalkeith in Perth (+$305K), and City Beach (+$300K).
- Melbourne and Canberra had fewer six-figure suburbs—just eight in Melbourne and five in Canberra—mainly in high-value pockets.
What’s Behind the Surge?
REA economist Anne Flaherty explains that higher-value suburbs inherently see larger dollar increases even with moderate percentage growth. As she puts it, “in a low-median suburb you might see a higher percentage growth, but…in dollar terms that growth is not going to be as strong…”
Additionally, interest rate cuts are amplifying capital growth in markets with larger mortgages, such as NSW, by increasing borrowing capacity—fueling stronger demand even in expensive suburbs.
Who’s Benefiting?
- Homeowners in high-growth suburbs (e.g. those living in Eastern Sydney or coastal Perth) are seeing massive equity windfalls—often hundreds of thousands in just half a year.
- Investors are clearly active—especially in Brisbane, Adelaide, Perth and regional areas—drawing competition in affordable markets.
- First-home buyers and upsizers may be priced out in boom areas, prompting shifts toward emerging markets where six-figure growth is still possible but price points are lower.
Looking Ahead: Will This Continue?
The bullish forecast continues. Flaherty believes home prices will keep rising throughout 2025, supported by interest rate cuts, strong demand, and potentially constrained listings as homeowners delay selling.
Reduced inventory—especially during the winter season combined with vendors staying put—could tighten supply and drive further price growth.
