The Australian property bubble is the economic theory that the Australian property market has become or is becoming significantly overpriced and due for a significant downturn (also called a correction or collapse). Since the early 2010s, various commentators, including one Treasury official, have claimed the Australian property market is in a significant bubble.
Various industry professionals have argued that it is not a bubble and that house prices have the potential to keep rising in line with income growth. The RBA believe that most of the recent rise in property prices since the 1980s, when interest rates have decreased from medium term record highs to record lows, as a transmission mechanism to generate the wealth effect and stimulate the economy.
A real-estate bubble is a form of economic bubble normally characterised by a rapid increase in market prices of real property until they reach unsustainable levels relative to incomes and rents, and then decline. Australian house prices rose strongly relative to incomes and rents during the late 1990s and early 2000s; however, from 2003 to 2012 the price to income ratio and price to rent ratio both remained fairly steady, with house prices tracking income and rent growth during that decade. Since 2012 prices have once again risen strongly relative to incomes and rents. In June 2014, the International Monetary Fund (IMF) reported that house prices in several developed countries are "well above the historical averages" and that Australia had the third highest house price-to-income ratio in the world.ABC News, 12 June 2014: Australia has third highest house price-to-income ratio in the world: IMF In June 2016, the Organisation for Economic Co-operation and Development (OECD) reported that Australia's housing boom could end in 'dramatic and destabilising' real estate hard landing.ABC News, 3 June 2016: Housing boom could end in a 'dramatic and destabilising' real estate hard landing: OECD
Australian property market
The Australian property market saw an average real price increase of around 0.5% per annum from 1890 to 1990, approximately matching CPI. Since the 1990s, however, prices have risen faster resulting in an elevated price to income ratio.
In 2023, Australia experienced eighth consecutive quarters of house price rises, and 7 quarters of apartment price rises. From 2002 to 2024, the median house price rose from 4.9 times the median gross disposable household income to 8.6 times.
By 2026, a solo purchaser earning the average Australian full-time wage would be unable to purchase a typical house in every Australian capital city. They would also be unable to purchase a median-priced apartment in Sydney, Brisbane, Adelaide or Perth.
The Housing Affordability in Australia - Good house is hard to find report stated that "the average house price in the capital cities is now equivalent to over eight years of average earnings; up from three in the 1950s to the early 1980s. Some factors that may have contributed to the increase in property prices include:
greater availability of credit due to financial deregulation. low interest rates since 2008, increasing borrowing capacity to borrow due to lower repayments. limited government release of new land (reducing supply). the average floor area of new houses has increased by up to 53.8% in the 18 years from 1984–85 to 2002–03. a tax system that favours investors and existing home owners, with policies such as negative gearing and capital gain tax discounts. government restrictions on the use of land preventing higher density land use. government restrictions on greenfield development designed to encourage "urban densification". high population growth (about double the world average in 2010- see Population growth rates chart). 2008 foreign investment rule changes for temporary visa holders. introduction by local councils of upfront infrastructure levies in the early 2000s. implementation of government schemes such as the first home buyers and first home builders schemes, which increase demand and therefore prices (supply and demand).
Influence of planning laws
Beginning in the 1980s, Australian states (who under the Constitution have control of environmental and land use issues) started progressively implementing more rigid planning laws that regulated the use of land. Planning laws often concentrated, after the 1990s, on restricting greenfield development in favour of "urban densification", or infill development. Land rationing is a system of banning development in all but designated areas, and can lead to extreme land price inflation if insufficient land is designated as allowed to be developed.
The restrictive planning laws in Australia have used land rationing systems as part of the goal of restricting greenfield development in favour of infill development, but this inevitably lead to land prices, and thus house prices, rising significantly. The initial thesis of YIMBY Melbourne was that local opposition to development was limiting the development of new housing, however planning restrictions were later considered to be significant.
Australian commentators often point to the experience of "The Auckland lesson", in which broad planning reform "abolished single-family zoning and allowed medium-density housing across" across most of the city, as a solution for Australian cities. Others claim the effect of planning restrictions is overstated; The Fifth Estate claimed that the "Auckland “miracle” has been roundly debunked by academics who say the data and analysis are deeply flawed."
Others have argued that planning laws do not affect housing supply, or that a housing supply shortage is not causing expensive housing. Academic Cameron Murray has argued that the idea that the shortage of housing supply due to town planning constraints is a "myth". His book The Great Housing Hijack, longlisted for the 2024 Australian Political Book of the Year award, claims that planning and zoning rules do not change how much new housing is built, only where they are built. This book has been critiqued by the Grattan Institute.
The Australian Council of Social Service wrote in 2025 "policies that focus exclusively on boosting housing supply, while needed, will not resolve the crisis on their own".
There is good evidence to suggest that the price of a new unit of housing is the ultimate anchor of all housing in an area, so when planning laws that implemented land rationing severely drove up the cost of new homes, all other homes followed suit.
Heritage and opposition to development
Historically there has been significant opposition to medium and high rise housing development. Opposition to development have framed their objections as a "fight to retain character" of the suburb. "NIMBYs have exploited heritage loopholes to prevent development". More recently, the 2026 Ipsos Life in Sydney survey found 48% of people strongly or tended to support increased residential housing density in their neighbourhood. This figure was 46% in 2025 and 44% in 2024. 17% were strongly opposed and 18% ambivalent.
The Australian YIMBY movement gained pace as the lack of housing supply caused property prices to climb. Groups such as Sydney YIMBY were started to advocate for greater housing supply.
Influence of tax system
The Reserve Bank of Australia has noted that there are "a number of areas in which the taxation treatment in Australia is more favourable to investors than is the case in other countries." The main tax incentives include tax deductions for losses on investment properties, even those that have been negatively geared, and the 50% discount on capital gains on sale of investments properties.
Investors using their superannuation for property investments have a tax advantage compared to 'savers' who are effectively taxed up to 45% (the top marginal taxation rate) on income from bank interest or bonds, as superannuation contributions are normally only taxed at around 15%.
The Australian government spends more on tax breaks for landlords than social housing, homelessness and rent assistance combined. Research by the Australian Council of Social Service (ACOSS) states that tax concessions for landlords cost $12.3bn in 2025.
In 2019, Deloitte Access Economics found tax reform (the 'ALP policy scenario') would on average (across Australia) reduce existing property prices by 4.6% (or 8.3% specifically for Greater Sydney and Melbourne) and new property prices by 4.6%.
The Grattan Institute wrote in 2016 their "best estimate is that the changes we recommend might lead to property prices up to 2 per cent lower than otherwise". Such a tax change corresponds to a few months of housing price growth.
An OECD report in 2026 advocated for replacing state-based property stamp duties with a land tax.
In February 2026 the Australian Council of Social Service recommended to curb the 50% CGT discount by halving it to 25% over 5 years and ending negative gearing for new investments (over 5 years for existing investments). The organisation previously stated economic modelling suggests this would reduce home prices by 1-4% and increase the home ownership rate by 2-5%.

Influence of banking system The influence of interest rates and banking policy on property prices has been noted. The financial deregulation has led to greater availability of credit and a variety of financial products and options. Presently the Reserve Bank of Australia has maintained for some time a low cash interest rate policy which has also reduced the cost of financing property purchase. In addition, the easy availability of interest-only loans has also made possible for property investors to borrow to purchase a property and compounding the benefits of negative gearing.
According to Amnesty International, housing has "increasingly been treated as a means to make money, rather than as a basic human right."
Housing costs excluded from the CPI One of the market distortions in the housing market relates to the calculation of the Consumer Price Index [CPI], a key metric the RBA uses to make fiscal policy decisions such as setting interest rates. One senior economist noted "The index ignores price changes in the single biggest purchase a person (or household) is likely to make in their lifetime – a dwelling″. This implies that Australia's main official cost of living measure is failing to represent actual living costs, particularly for younger Australians who may incur substantial costs of purchasing a home.Inflation data 'very poor' cost of living measure due to house price exclusion Michael Janda "ABC News", 20 April 2017
