Why Labor’s 5% Deposit Schemes Makes Housing Less Affordable

Key Takeaways

• 5% deposit scheme launched Oct 1 2025 across major Australian cities
• Bottom‑quartile home prices rose fastest in March 2026
• Price caps failed to curb inflation in targeted segment
• Demand‑side subsidies can push up overall property values
• Analysts warn scheme may reduce overall housing affordability

Pulse Analysis

The 5 % deposit scheme was introduced as a demand‑side measure to lower the cash barrier for first‑time homebuyers. By guaranteeing a government‑backed loan that covers five percent of a property’s price, the policy aims to broaden access to homeownership in markets where median prices have outpaced wage growth. While well‑intentioned, the approach does not address the chronic supply shortage that drives Australian housing prices, and it assumes that easing cash flow constraints will not alter buyer behaviour.

Recent data from Cotality’s housing chart pack reveal a counter‑intuitive outcome: homes in the bottom quartile—those that fall under the scheme’s price caps—experienced the steepest price appreciation between October 2025 and March 2026. Economists explain that the subsidy boosts purchasing power, prompting more buyers to compete for the same limited inventory, which in turn lifts transaction prices. This demand‑side pressure is amplified in capital‑city markets where land constraints and zoning rules already restrict new construction, meaning the extra buying power translates directly into higher bids rather than new supply.

The broader implication is a potential feedback loop where government assistance inadvertently erodes the very affordability it seeks to protect. Policymakers may need to complement deposit subsidies with supply‑side interventions such as zoning reforms, incentives for high‑density development, or direct investment in affordable housing stock. Without such measures, the scheme risks becoming a costly catalyst for price inflation, leaving first‑time buyers facing steeper entry costs despite the nominal assistance. A balanced strategy that aligns demand relief with tangible supply growth is essential for sustainable housing affordability.
