Australian property market decline driven by interest rates, affordability, and tax changes

By Updated 5 June 20265 articles from 4 sources

Consensus Summary

Australian property markets, particularly in Sydney and Melbourne, experienced sharp declines in May 2026 as higher interest rates (4.35%), affordability pressures, and federal tax reforms on negative gearing and capital gains weighed on values. Sydney’s median house price fell to $1.58 million after peaking at $1.6 million, while Melbourne’s median house price dropped to $958,000. Regional markets like Perth and Brisbane saw gains, but growth slowed nationally. Experts like Cotality’s Tim Lawless and AMP’s Shane Oliver predict further declines of 5–10% over the next year, driven by sustained high rates and reduced investor demand. Housing Minister Clare O’Neil dismissed tax changes as the primary cause, attributing most pressure to interest rate hikes. Rental prices rose 5.9% annually, with vacancy rates at a record low of 1.5%, while auction clearance rates weakened, signaling a prolonged market correction.
