Million-dollar house prices are becoming the new normal in Australia’s fastest growing suburbs, with about half of the top 30 capital city suburbs for annual growth now recording medians above $1 million, according to new PropTrack data.
That marks a shift from recent years when suburbs with the strongest percentage growth were typically in the more affordable $500,000 range. With lower-priced suburbs having already surged, growth has slowed in those markets, and higher-value areas are now topping the leaderboard.
The Reserve Bank’s interest rate cuts through 2025, which lowered the cash rate to 3.6% — the lowest since April 2023 – have boosted borrowing power and broadened demand.
PropTrack’s August Home Price Index confirmed this upswing, showing national home prices rose 0.5% in August, the eighth straight monthly gain, leaving values 5.3% higher year-on-year.
Adelaide suburbs dominated the growth rankings. Beachside Semaphore led the nation with a 39% rise to a median of $1.185 million, followed by Marden in the inner north-east and Somerton Park in the south-west.
REA Group executive manager of economics Angus Moore (pictured) said falling rates were likely supporting upgrader demand.
“With rates starting to come down, affordability is beginning to improve a bit,” Moore said.
“On top of that, many buyers in smaller capitals are sitting on significant equity, with prices having nearly doubled over the past five and half years. That combination might be driving upgrader demand in some of these more expensive areas.”
Real estate agent and Noakes Nickolas director Simon Noakes said lifestyle suburbs like Somerton Park were attracting families with equity to trade up.
“It’s just gone from strength to strength,” Noakes said. “It’s become a really family-orientated area – it’s quiet with beautiful streets, and the beaches in Somerton Park would be up there with the best in Australia. Plus, the proximity to the city and the ability to get a full-sized block makes it a pretty desirable area.”
He said recent price gains and rate cuts had opened up more options for existing homeowners.
“There's been a bit of movement with people building up so much equity in their property since COVID,” Noakes said. “That’s given them choices and options.”
Perth’s pricier suburbs also made the list, including Trigg, West Leederville, and Bicton. Duet Property Group’s Craig Gaspar said upgraders were driving demand in West Leederville.
“The location is so central,” Gaspar said. “We’re seven minutes from the city and seven minutes to the beach. You can walk to a train, and we’re surrounded by very good public schools.”
He noted tight supply was pushing prices higher.
“Vendor expectations have now gone to a different level,” Gaspar said. “I don't see the stock situation changing for a very long time, so there’s still going to be that pressure on pricing.”
Brisbane’s Ipswich region also featured prominently due to its affordability, around 40km from the CBD. Century 21’s Josie Smith said it remains popular with younger families.
“People come out this way for the lifestyle as well,” Smith said. “A lot of Ipswich suburbs still offer lower density living. Ipswich has a predominately younger demographic. There are a lot of younger families and first-home buyers moving here. There's a lot more planned infrastructure to come for the region and that puts us on the map for job growth as well.”
Outer-ring suburbs priced between $500,000 and $750,000 remain in demand among first-home buyers and investors, with areas such as Elizabeth North in Adelaide and Bullsbrook in Perth recording strong growth.
However, analysts noted some investors are shifting to alternative markets such as Darwin, Albury, and Mildura. Expanded eligibility under the federal government’s First Home Guarantee scheme could also open up more capital city suburbs for first-home buyers as higher price caps take effect.
