Sydney’s rental market has become a story of extremes. On one side of the harbour, renters in suburbs like Vaucluse, Mosman, and Bellevue Hill are paying more than $2,000 a week for houses overlooking the water. On the other, tenants in Carramar, Cabramatta, and Mount Druitt are hanging on to what little affordability remains, as vacancy rates across the city fall to record lows.
Cotality’s October 2025 Quarterly Rental Review puts Sydney’s median rent at $807 per week, up 3.5 per cent over the year. Vacancies have slipped to 1.6 per cent, compared with 2.3 per cent a year earlier, signalling an increasingly competitive market.
The data shows listings are 25 per cent below the five-year average, keeping pressure on tenants even as rent growth slows slightly from earlier surges. While the third quarter saw a modest 0.8 per cent increase, the broader trend remains upward, with supply shortages across all dwelling types.
The prestige end of the market continues to shape national benchmarks. Harbourside postcodes have again topped the charts, led by Vaucluse, where median house rents are $2,148 per week. Rose Bay follows at $2,031, Mosman at $1,966, and Dover Heights just shy of $1,950. Even with minor quarterly dips in Bronte and Bellevue Hill, most elite suburbs still command more than two and a half times the Sydney median.
These pockets share a common thread: limited development potential and consistently high-income tenants. Harbourside scarcity remains the main price driver, keeping rents high and yields compressed. Most houses in these areas now return between 1 and 2 per cent, well below the city average of 3 per cent, yet demand remains undeterred.
Further west, the picture shifts sharply. The most affordable suburbs, mainly in Sydney’s South-West and the Central Coast, still offer units below $500 per week, though such listings are vanishing fast. Carramar is the cheapest at $442, followed by Cabramatta at $472 and Canley Vale at $476. Yields here range from 4.5 to 6 per cent, drawing investors seeking better returns than the city’s core markets can offer.
Cotality’s report shows six of the ten most affordable areas sit along the South-West rail corridor, where access to jobs and ongoing infrastructure projects are attracting lower- to middle-income renters. Yet even these pockets of relative affordability are tightening, with vacancy rates now below 1.5 per cent in much of Western Sydney.
For investors, Sydney’s market presents a paradox. While rising capital values have eroded rental yields, regulatory changes and higher compliance costs have added new challenges. For renters, affordability is slipping further out of reach, with few signs of relief in the year ahead.
The imbalance between population growth and new housing completions continues to weigh heavily on the market. Unless supply meaningfully improves, analysts warn that Sydney’s bifurcated market will persist—premium rents at the top, marginal affordability at the bottom.
