As housing prices continue to rise across Australia—particularly in Sydney, where the median house price is now nearing $1 million—it’s more important than ever to understand the supply and demand factors influencing the property market.
This guide explores the critical demand-side and supply-side forces shaping real estate trends in 2025 and how these factors affect property values, affordability, and investor decisions.
Demand-Side Factors Influencing the Australian Housing Market
1. Affordability of Housing
Income levels directly affect a buyer’s ability to purchase property. As household income rises, so too does purchasing power, increasing demand for housing. During periods of economic growth, buyers can afford to spend more on property, resulting in upward pressure on prices. In contrast, a recession tends to reduce housing demand.
As of late 2018, Australia’s national housing value-to-income ratio dropped to 6.7 from a peak of 7.0 in 2017. While this suggests improved affordability, the shift has been driven by falling property values rather than an increase in wages.
2. Speculative Demand and Buyer Confidence
Housing demand is also influenced by buyer confidence and expectations of future capital growth. When buyers believe prices will continue to rise, demand increases as people rush to secure properties before prices climb further. This speculative demand is particularly strong during periods of economic optimism and low interest rates.
3. Interest Rates
Mortgage interest rates are one of the most significant factors influencing demand. Lower rates reduce the cost of borrowing and increase a buyer’s ability to service a loan. Australia’s interest rates fell to an all-time low of 0.10% in November 2020, following a long-term trend of declining rates since the 1990s.
These record-low interest rates contributed significantly to the price surge between 2012 and 2017 and again during the COVID recovery in 2021.
4. Population and Household Growth
A growing population drives increased housing demand. Australia’s current population of approximately 26 million is projected to reach over 41 million by 2061. The number of households is expected to grow from 9.2 million in 2016 to between 12.6 and 13.2 million by 2041.
This demographic pressure increases the demand for housing, particularly in major urban centres.
5. Availability of Mortgage Lending
Access to credit also affects buyer behaviour. When banks are willing to lend at higher income multiples, more people can afford homes, increasing demand. According to the AIHW, over 17% of households spent more than 30% of their gross income on housing in 2017–18, with 5.5% spending over 50%.
Home ownership rates have declined among lower-income households due to the rising cost of housing and limited access to affordable loans.
6. Economic Growth
Rising national income and employment levels tend to boost buyer confidence and support increased demand for housing. Following the economic downturn in 2020 due to COVID-19, Australia saw strong recovery in 2021 and beyond, with property values rising in every capital city.
7. Cost of Renting
Higher rental costs often push renters to become buyers, increasing demand for owner-occupied properties. As of 2020, the average weekly rent for a three-bedroom house in Australia reached $560 before briefly dropping due to COVID restrictions.
Supply-Side Factors Affecting the Property Market
1. Number of Listings
The volume of homes listed for sale directly affects supply levels. More sellers increase the availability of housing, helping to temper price growth. A shortage of listings, however, can drive up competition and prices.
2. Housing Supply and New Builds
A significant drop in new home construction is expected by 2023—down 25% from the peak in 2015–16, according to The Australian Financial Review. While new builds increase supply, delays in construction and land scarcity, particularly in Sydney, continue to limit available housing stock.
Young investors entering the market are contributing to the construction boom, but this supply has yet to meet long-term demand trends.
3. Land Availability and Planning Restrictions
Zoning rules, infrastructure limitations, and natural barriers restrict land availability, particularly in capital cities. In Sydney, for example, National Parks and water bodies limit outward expansion, driving prices higher in established suburbs.
Long-Term Influences on Property Prices
While interest rates and population surges can shift short-term demand, long-term trends often have a more sustained effect on prices. Key examples include:
- Decreasing household sizes: More people require separate dwellings, increasing housing demand.
- Urban constraints: Cities like Sydney face natural limits to expansion, causing increased competition in established areas.
- Lagging construction: Supply has trailed demand for decades, exacerbating the housing shortfall.
These structural issues support the continued upward trajectory of home prices, especially in high-demand markets like Sydney and Melbourne.
