Government incentives drive first home buyer activity
The outperformance of affordable housing coincides with an unprecedented expansion of first home buyer support schemes. The federal government's decision to bring forward and significantly expand the First Home Buyer Guarantee scheme to October 2025 - three months ahead of schedule - has removed key barriers for entry-level buyers.
The expanded scheme eliminates income caps entirely and dramatically raises property price thresholds to $1.5 million in Sydney (from $900,000), $950,000 in Melbourne (from $800,000), and $1 million in Brisbane (from $700,000). This allows first home buyers to purchase with just a 5 per cent deposit without paying lenders mortgage insurance, potentially saving tens of thousands of dollars in upfront costs.
Treasury estimates suggest the uncapped scheme will issue an additional 20,000 guarantees in its first year, directly targeting the affordable segment where competition is most intense. The department's modelling indicates this will add approximately 0.5 per cent to house prices over six years, though the immediate impact appears concentrated in the entry-level market.
Beyond federal schemes, first home buyers benefit from various state-based incentives including stamp duty exemptions, grants, and shared equity programs. These layered incentives create powerful demand drivers specifically targeting properties in the affordable tier.
Melbourne and Canberra buck the trend
Notably, Melbourne and Canberra stand out as exceptions to the affordable outperformance story. Melbourne affordable houses are growing at 4.2 per cent annually, actually lagging behind typical Melbourne properties at 4.3 per cent - the only major city where this occurs. Similarly, Canberra affordable houses trail typical properties by 0.2 percentage points.
For units, both cities show identical growth rates between affordable and typical properties, with no discernible premium for cheaper stock. This divergence likely reflects superior supply responses in both markets, with Canberra's apartment construction pipeline and Melbourne's established development industry better positioned to respond to entry-level demand.
Melbourne's extensive land supply and established infrastructure for medium-density housing has historically enabled more responsive construction of affordable homes. Meanwhile, Canberra's compact urban form and active government land release program supports consistent apartment development at various price points.
Supply constraints amplify competition
The limited stock of affordable housing in most markets is intensifying competition among entry-level buyers. With median house prices now approaching $1 million nationally, the pool of sub-$800,000 properties has shrunk dramatically, concentrating demand among remaining affordable options.
Unit markets are showing even stronger affordable outperformance, with Perth leading at 16.5 per cent annual growth for affordable units compared to 14.5 per cent for typical apartments. Regional Queensland and Regional South Australia units both show 3.1 percentage point premiums for affordable stock, highlighting the acute shortage of entry-level apartments outside major cities.
The combination of government incentives, constrained supply, and demographic pressures from millennials entering peak home-buying years is creating a structural shift in how different price segments perform. This trend appears likely to persist while government support remains targeted at first home buyers and affordable housing supply constraints continue.
The data suggests that while overall market conditions drive broad price movements, policy interventions and supply dynamics are creating increasingly divergent performance across price tiers, with significant implications for housing affordability and market structure going forward.
