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, [1] 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. [2]
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. [3] 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. [4] 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. [5]
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. [6]
In the late 2000s, house prices in Australia, relative to incomes, were at elevated levels similar to many comparable countries, prompting speculation that Australia was experiencing a real estate bubble like other comparable countries. Since then, several comparable countries have experienced property crashes.
All capital cities have seen strong increases in property prices since about 1998. Sydney and Melbourne have seen the largest price increases, with house prices rising 105% and 93.5% respectively since 2009. These massive increases in house prices coincide with record low wage growth, record low interest rates and record household debt equal to 130% of GDP. This indicates unsustainable growth in property, driven by ever higher debt levels fuelled by the RBA's then chief, Glenn Stevens who began cutting rates beginning in 2011.[ citation needed ]
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. [7] Some factors that may have contributed to the increase in property prices include:
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. [13] Planning laws often concentrated, after the 1990s, on restricting greenfield development in favour of "urban densification", or infill development. [14] [15] 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. [15] 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. [16] 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.[ citation needed ]
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." [17] 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%.[ citation needed ]
The list of tax payer funded supports to the property market are numerous
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.
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″.[ citation needed ] 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. [18]
In 2007, The Australian published an article on housing affordability and discussed multiple factors influencing rising house prices. It cited Macquarie Bank analyst Rory Robertson who noted that low interest rates in the 1990s, reductions in capital gains tax, and buyer preferences for well-located properties had contributed significantly to increasing prices. High levels of immigration were identified as a factor adding to demand in major cities, but the article emphasized that other structural economic and policy factors were major drivers. The report also highlighted that substantial land was available for residential development, suggesting that limited land supply alone did not account for affordability pressures. [19] A 2006 Sydney Morning Herald article reported on economist Robertson’s analysis of Australian housing affordability. Robertson criticized claims by then-Prime Minister John Howard that state government land release policies were the main driver of high house prices. He argued that a number of factors including high immigration, lower interest rates since the early 1990s, and investor activity, had a greater impact on housing costs. [20]
The Productivity Commission Inquiry Report No. 28 First Home Ownership (2004) also stated, in relation to housing, "that Growth in immigration since the mid-1990s has been an important contributor to underlying demand, particularly in Sydney and Melbourne." [21] This has been exacerbated by Australian lenders relaxing credit guidelines for temporary residents, allowing them to buy a home with a 10% deposit.
The RBA in its submission to the same PC Report also stated "rapid growth in overseas visitors such as students may have boosted demand for rental housing". [21] However, in question in the report was the statistical coverage of resident population. The "ABS population growth figures omit certain household formation groups – namely, overseas students and business migrants who do not continuously stay for 12 months in Australia." [21] This statistical omission lead to the admission: "The Commission recognises that the ABS resident population estimates have limitations when used for assessing housing demand. Given the significant influx of foreigners coming to work or study in Australia in recent years, it seems highly likely that short-stay visitor movements may have added to the demand for housing. However, the Commissions are unaware of any research that quantifies the effects." [21]
In a 2008 gov report, some individuals and interest groups have also argued that immigration causes overburdened infrastructure. [22]
According to a 2025 BBC article, immigration and foreign property purchases have been frequently cited as causes of Australia’s housing crisis. However, experts and statistical analyses indicate that these factors are not significant contributors to rising house prices. Instead, housing affordability issues are more strongly linked to limited supply, tax incentives for investors, and broader demand-side pressures. [23]
In December 2008, the federal government introduced legislation relaxing rules for foreign buyers of Australian property. According to FIRB (Foreign Investment Review Board) data released in August 2009, foreign investment in Australian real estate had increased by more than 30% year to date. According to one real estate agent, "overseas investors buy them to land bank, not to rent them out. The houses just sit vacant because they are after capital growth." [24]
In April 2010, the government announced amendments to policies to "ensure that foreign non-residents can only invest in Australian real estate if that investment adds to the housing stock, and that investments by temporary residents in established properties are only for their use whilst they live in Australia." [25] [26]
Under the rules, temporary residents and foreign students will be:
Failure to do this would also lead to a government-ordered sale. [27]
Several Australian Banks and lenders provide home loans to non-residents for the purchase of Australian real estate. In 2021, a survey reported by The Guardian found that more than 80% of Australians believed Chinese investors were driving up house prices, despite a year of closed borders and record-low levels of foreign property investment. Lead author of the survey, Elena Collinson, suggested that sensationalist media coverage had contributed to this misconception, noting that the idea of Chinese investors as the main drivers of a difficult-to-enter housing market persisted even in the face of contrary evidence. [28]
Data compiled by the National Australia Bank shows that foreign investors accounted for only 3.7% of new home sales and 2.2% of established homes in the March quarter of 2025, with the figures including all foreign buyers, indicating that Chinese investment is likely even lower. Eliza Owen, head of research for Australia at CoreLogic, noted that foreign investment has been trending downwards since 2014 and that the numbers are not significant enough to explain most of the recent housing price increases, which are instead driven by low interest rates, strong owner-occupier demand, and limited supply. [28]
From April 2025, a 2 year temporary ban has been placed on foreign investment in established property, aimed to reduce competition in the property market. This will be reviewed in 2027 and potentially extended. [29]
In 2002, the government initiated a Productivity Commission Inquiry into the homes ownership in Australia. The commission's report entitled "First Home Ownership" [30] observed inter alia that "general taxation arrangements [capital gains tax, negative gearing, capital works deductions and depreciation provisions] have lent impetus to the recent surge in investment in rental housing and consequent house price increases."[ citation needed ]
The government's response to the report stated that "There is no conclusive evidence that the tax system has had a significant impact on house prices." [31]
In 2008, another study was commissioned – the 2008 Senate Select Committee on Housing Affordability in Australia. [32] The report noted that "On some measures, housing affordability is at a record low.
"Australia's Future Tax System" (AFTS) review, more commonly known as the "Henry Tax Review", made a number of recommendations that would have impacted on the housing market, including:
In regard to recommendations of changes to tax policy that might impact the housing market, the Government advised "that it will not implement the following policies at any stage" (excerpt of list):
In May 2015, the House of Representatives Standing Committee on Economics started an Inquiry into Home Ownership. Almost two years later the announcement was made that the Inquiry had made no recommendations whatsoever. [35]
In 2017, a Royal Commission into Misconduct in the Banking, Superannuation and Financial Services Industry was established. Hearings into banking misconduct began on 13 March.
Increased residential housing costs can cause excessive lending to the residential housing sector, at the expense of businesses. This can lead to "a banking system which allocated capital away from the most productive areas of the economy — business — is ultimately bad for growth, bad for competition, bad for jobs, bad for business and in the end, bad for Australia." [36]
Research conducted in overseas markets confirms that "in areas with high housing appreciation, banks increase the amount of mortgage lending and decrease the amount of commercial lending as a fraction of their total assets. This allocation results in firms receiving reduced loan amounts, paying higher interest rates, and reducing investment." [37]
Increased housing prices and therefore increased borrowings can lead to difficulty in meeting housing payments. According to Ratings agency Standard & Poor's (S&P), "Arrears for sub-prime loans backing RMBS [residential mortgage-backed securities] jumped 126 basis points to 11.45 per cent" [38]
The Australian market had several features either singly or together are not typical in other housing markets, being;
When Australia’s borders were closed during COVID-19, migration dropped to its lowest level in a century, yet house prices continued to rise. This indicates that migration is not the primary driver of the country’s housing crisis. Nevertheless, some political actors have blamed migrants for housing unaffordability, presenting an oversimplified view of a complex problem. [96] [97]
Experts and housing advocates emphasize that the housing crisis has developed over decades due to structural factors rather than migration alone. These include chronic undersupply of housing, rising construction costs, tax incentives favoring investors, and repeated policy failures. [98] [23] CoreLogic’s head of residential research, Eliza Owen, noted that migrants were entering an already tightening rental market, and it is “definitely not fair to only target overseas migrants as something that is contributing to the housing crisis.” She added that changes in household sizes and insufficient provision of social and affordable housing have been major contributors to the problem. [99]
Research has supported this perspective. A University of South Australia study examining rental data between 2017 and 2024 found no statistically significant correlation between international student numbers and rent costs in any major city, even after controlling for overall rental inflation. [100]
Experts further warn that cutting migration could have long-term economic consequences. Brendan Coates of the Grattan Institute explained that reducing migration would decrease the number of skilled workers and result in lost revenue, potentially raising taxes for Australians. Many industries, including healthcare and education, rely heavily on skilled migration, which contributes to national productivity and long-term economic growth. [23] The Guardian reported that short-term reductions in permanent migration intake may have little effect, as many applicants are already in Australia on temporary visas and would remain in the country. [96]
A 2025 report by The Guardian noted that economic modelling by KPMG indicates that reducing migration could have negative effects on both housing affordability and the broader economy. The modelling projected that eliminating migration for a decade would result in house prices being 2.3% higher by the mid-2030s compared with a scenario in which migration continues as expected. It also predicted a smaller workforce, slower economic growth, increased national debt, and reduced capacity to fund essential services in an ageing population. Brendan Rynne, chief economist at KPMG, stated that migrants, who are generally younger and more highly educated, contribute skills and innovation that help maintain productivity in an ageing society. Rynne explains that when migration is sharply reduced, the lower demand for housing is offset by a reduced workforce available to construct homes, and that higher wages would also contribute to inflation, reducing the benefits of increased pay. He adds that while migration is not a solution to all economic challenges, a well-managed migration program provides greater economic benefits than harm over the long term. [101]
Australia’s Race Discrimination Commissioner, Giridharan Sivaraman, has highlighted that housing stress, economic inequality, and job insecurity are pressing challenges affecting all Australians, including migrant communities, and warned against using migrants as scapegoats. [102] [103]
