Western Sydney is heading into 2026 with the kind of demand profile most markets would envy – strong population growth, major infrastructure investment, and rising buyer activity.
For mortgage brokers, however, the latest RWC Western Sydney research underscores a tougher reality: actual building activity is lagging well behind what’s needed, with implications for borrowing capacity, sensitivity to mortgage rates, rents, and long‑term affordability for clients.
Report author Peter Vines (pictured), managing director at RWC Western Sydney, says bluntly that “Western Sydney’s housing challenge remains one of activation, not aspiration,” and argues the region has become a textbook example of approvals outpacing delivery.
Population projections show Western Sydney absorbing nearly 59,000 new residents each year through to 2041, requiring 25,636 new homes annually across detached houses, townhouses, and apartments. Yet only 5,484 dwellings are currently under construction, leaving a sizeable structural gap at a time when average household sizes are shrinking and more smaller dwellings are needed.
At the same time, finance data point to a robust demand backdrop. The average NSW owner-occupier loan size has risen to $873,000, well above the $717,000 national average, highlighting the higher debt loads many Sydney borrowers are carrying into a higher-rate environment.
While borrowers are taking on larger debts, the supply side is struggling to respond.
Vines warns that “The pipeline is there. The approvals are there. What’s missing is the ability to convert those approvals into homes at the pace the region actually requires.”
More than 82,000 dwellings sit in the development pipeline, but labour shortages, feasibility constraints and infrastructure servicing issues are delaying commencement.
The report also links Western Sydney’s supply shortfall with a broader demographic shift.
New South Wales posted a net interstate loss of 24,328 residents in 2024/25, with departures far outweighing arrivals. Queensland and Western Australia absorbed most of this outflow, supported by relatively lower housing costs and improving job markets.
According to Vines, “NSW keeps losing residents to Queensland and WA, and the reason isn’t weather or lifestyle – it’s housing,” a trend that effectively exports workers and potential borrowers from Western Sydney to competing states.
The 2026 opening of Western Sydney Airport is expected to turbocharge employment-driven demand, particularly in the South West precinct – already the region’s fastest-growing area but currently building only a fraction of the 7,335 homes it needs each year.
Without a lift in construction, brokers can expect further upward pressure on rents and prices as workers chase limited stock.
Policy support is fuelling demand from first-home buyers as well. Commitments hit 7,750 in the December 2025 quarter, the strongest result since mid‑2021, helped by an expanded First Home Guarantee that slashes deposit hurdles.
As Vines notes, “The policy support is working; more first-home buyers are in the market than we’ve seen in years,” but without more dwellings, those buyers are increasingly competing for the same limited supply.
For brokers, the message is clear: Western Sydney remains a key growth market, but the real risk factor is not demand – it is delivery. Understanding how that activation gap plays through into pricing, serviceability, and product selection will be critical for clients in the years ahead.
