In this article, we’ll dive into the factors contributing to high house prices in Australia, from supply and demand issues to tax policies and rising interest rates.

Factors contributing to high house prices in Australia
The following are key factors that contribute to the increase in average house prices in the country:
Supply and demand imbalance
One of the primary reasons for high house prices in Australia is the imbalance between supply and demand. Housing supply is under ongoing strain due to an increasing population and a limited land supply, particularly in large cities like Melbourne and Sydney.
This increased demand, combined with an inadequate supply response, drives up the average residential property prices.
Challenges in boosting regional housing supply
Attempts to increase regional housing supply have faced various obstacles, such as zoning restrictions, infrastructure limitations, and local opposition to development.
These challenges make it difficult to address poor housing affordability across the country.
Land and infrastructure costs
Another factor contributing to high house prices in Australia is the increasing cost of land and infrastructure. Land prices have been rising due to factors such as limited availability, especially in urban areas, and competition among developers.
Additionally, the cost of developing new infrastructure, such as roads, utilities, and public services, also contributes to higher property prices.
Impact of foreign investment
Foreign investment in the Australian property market has also played a role in driving up house prices. Investors from overseas, particularly from countries with strong economies, have been attracted to the Australian market due to its stability and potential for capital growth.
The increased interest from overseas buyers has helped drive up home prices.

Tax policies and regulations
Australia’s tax system also plays a significant role in driving up house prices. Policies like capital gains tax discounts and negative gearing have made property investment attractive for existing property owners, further inflating prices.
Capital gains tax discount
The capital gains tax discount provides a financial incentive for Australians to invest in property, as it reduces the amount of tax payable on profits from the sale of an investment property. This policy has encouraged property speculation and contributed to rising house prices.
Negative gearing
The term “negative gearing” refers to the policy of allowing property investors to deduct losses from their taxable income due to the purchase of investment properties. This boosts real estate speculation, which in turn can increase demand for homes and push up prices.
High interest rates and mortgage policies
The high interest rates in Australia have made housing more expensive in a number of ways.
- Higher monthly repayments: When interest rates rise, the monthly repayments on a mortgage also rise. This can make it more difficult for people to afford to buy a home, and can also make it more difficult for existing homeowners to keep up with their repayments.
- Reduced borrowing capacity: When interest rates rise, the amount of money that people can borrow from a bank decreases. This is because banks need to factor in the increased risk of default when setting their lending limits. As a result, people may need to save a larger deposit before they can afford to buy a home, or they may need to purchase a less expensive home.
- Decreased demand: As interest rates rise, the demand for housing tends to decrease. This is because people are less likely to want to buy a home when they know that their monthly repayments will be high. As a result, housing prices tend to fall when interest rates rise.
Australian Prudential Regulation Authority’s role in housing finance
The Australian Prudential Regulation Authority (APRA) has introduced measures to slow lending and curb risky borrowing practices in response to rising house prices. However, the impact of these policies on housing affordability remains to be seen.

Rising household debt and income
High debt-to-income ratios and stagnant wage growth have made it difficult for many Australians to save for a deposit and enter the property market. As a result, demand for housing outstrips supply, making property price growth slow.
Impact of record-low wage growth on housing affordability
With wages failing to keep pace with rising property prices, housing affordability has become a pressing issue for many Australians. Houses are getting more expensive to build and buy. The widening gap between income and property prices has left many people struggling to break into the market.

More on the Australian housing market
How do interest rates affect house prices in Australia?
Low interest rates encourage more borrowing, increasing demand for homes and, as a result, house prices. Raising interest rates could help to alleviate house affordability issues.
What role do state and federal governments play in Australia’s housing affordability crisis?
State and federal governments are responsible for implementing policies that can improve housing affordability, including addressing supply and demand issues, tax policies, and supporting affordable housing initiatives.
How does the Australian housing market compare to other comparable countries?
Australian house prices are considerably higher than in many other comparable countries, largely due to factors such as supply and demand imbalance, tax policies, and low-interest rates.
