Housing affordability in Australia

Key Issue
The high cost of housing in Australia has been at the forefront of a range of recent policy debates concerning Australia’s taxation arrangements.  This brief examines housing affordability in Australia for both owners and renters over recent decades. It focuses particularly on those households which are most affected by high housing costs—those on low incomes in the private rental market.

What is housing affordability?   

The term ‘housing affordability’ usually refers to the relationship between expenditure on housing (prices, mortgage payments or rents) and household incomes. The concept of housing affordability is different to the concept of ‘affordable housing’, which refers to low-income or social housing.

Affordability for owners

Housing affordability in Australia has broadly declined since the early 1980s. The OECD’s price to income ratio index shows a 78% increase between 1980 and 2015. In Sydney, which has experienced significant price rises over the period, Parliamentary Library calculations indicate that the ratio of average disposable household income (Australia-wide) to median house prices has increased from approximately 3.3 in June 1981, to just over seven in June 2015. The following graph illustrates Australia-wide ratios from the early 1970s to 2012.

Much of the growth in housing prices relative to incomes took place during the late 1980s, 1990s and early 2000s. In this context, the Reserve Bank of Australia’s 2014 submission to the Senate Economics References Committee Inquiry into Affordable Housing noted ‘Australian housing prices increased by about two thirds relative to income in the decade or so up to around the end of 2003’.

Partly as a consequence of rising house prices between 1984 and 2009–10, the Australian Bureau of Statistics’ (ABS) Household Expenditure Survey indicates that the estimated proportion of average weekly household expenditure on current housing increased from approximately 12.8% to 18.0%. Some of this increase is likely to represent changing societal preferences, with households choosing to put more of their household budget into larger, more comfortable or better-located homes. This has been facilitated through financial deregulation and a significant growth in household disposable incomes between 1980 and 2010.

Of course, affordability differs between the states and territories, and between capital cities and regional areas. As an indication, Table 1 shows nominal median house prices in each of the capital cities in March 1980, and March 2016.

Rising house prices are one factor behind the declining levels of home ownership in Australia. The 2016 Household, Income and Labour Dynamics in Australia Survey: Selected Findings from Waves 1 to 14 reports that, in 2001, 68.8% of households were owner-occupied, compared to 64.9% in 2014. This trend is most prevalent in Victoria (7.8 percentage point decline) followed by New South Wales (4.3 percentage point decline), and South Australia (2.5 percentage point decline).

Measurements of housing affordability

There are two major approaches to the measurement of housing affordability in policy discussions in Australia—ratio measures and residual measures. Ratio measures focus on the relationship between housing expenditure (prices or costs) and household income, either as a median or mean. The ABS, the OECD and various housing industry associations publish ratio measures. As outlined by Gabriel, Jacobs, Arthurson, Burke and Yates in their 2005 paper Conceptualising and measuring the housing affordability problem, residual measures emphasise the capacity of a household to maintain an acceptable standard of living after housing costs. Given the level of complexity associated with their calculation, residual measures are typically published by researchers and academics.

Affordability for renters

The ABS’ Housing Occupancy and Costs publication indicates that between 1994–95 and 2013–14, the proportion of households which are renters has increased from 26% to 31%. In addition, the proportion of households renting from private landlords has increased from 18% to 26% over the same period.

On average, private renters spend more of their gross household income on housing costs than other tenure types. Specifically, the ABS reports private renters spent 20% of their gross household income on housing costs in 2013-14, compared with 16% for those with a mortgage.

The cost of renting privately has increased significantly over the period between
1994–95 and 2013–14. The ABS’ Housing Occupancy and Costs publication indicates a 62% increase in average weekly housing costs (after inflation). This compares to a 42% increase for owners with a mortgage and 45% for public renters.

What is housing stress?

A household is typically described as being in ‘housing stress’ if it is paying more than 30% of its income in housing costs. As higher income households can spend a higher proportion of their income on housing without experiencing problems, they are often excluded from these types of analysis. Consequently, a ratio of 30/40 is often used as a benchmark—that is, if households that fall in the bottom 40% by income spend more than 30% of their income on housing, they are defined as being in housing stress. Confusingly, both gross and disposable incomes are referenced by researchers when referring to housing stress.

Affordability in the private rental market for those on low incomes

Much of the recent public debate about housing affordability has focused on the inability of many would-be home owners—and young people in particular—to break into the property market, and factors contributing to this. Rather less attention has been paid to the difficulties faced by low-to-medium-income earners who are obliged to compete with people on higher incomes for a limited number of affordable rental properties in the private rental market in areas with greater employment opportunities.

In 2012, the National Housing Supply Council (NHSC) estimated that as at 30 June 2011, the gap between overall housing supply and demand was 228,000 dwellings. The NHSC also estimated that there was a deficit of 539,000 affordable rental properties for lower income renters. Anglicare Australia’s annual rental affordability snapshots suggest that the situation for lower income renters remains difficult. The latest Anglicare survey of 75,410 rental properties across Australia, conducted in April 2016, found that at a national level, only 21 properties were affordable for single adults living on Newstart Allowance, and only one was suitable for a single person living on Youth Allowance.

In this context, an increasing number of Australian renter households are experiencing housing stress. In 2013–14, the ABS found 50.1% of low-income renter households had housing costs greater than 30% of gross household income (which includes Commonwealth Rent Assistance (CRA)). While the provision of CRA has helped to reduce the number of Australian households in housing stress, Parliamentary Library calculations indicate that for a substantial and growing proportion of people renting in certain parts of Australia, rental costs are rising at a higher rate than CRA thresholds and rates.

For those low-income households in greatest need, the federal, state and territory governments provide social housing. However, the stock of social housing is not increasing at a rate sufficient to keep up with demand, and waiting lists for social housing remain long. At 30 June 2015, there were 199,133 households on social housing waiting lists.

Government response

Housing affordability did not receive significant attention during the 44th Parliament. The Government had committed to undertake a review of housing and homelessness policies and programs as part of the reform of the federation white paper process, with housing issues also to be considered as part of the white paper on the reform of Australia’s tax system. However, the status of this review is unclear given the cessation of both of the white papers.

On 7 January 2016, the Government announced that the COAG Council on Federal Financial Relations would form an Affordable Housing Working Group. This group has been charged with identifying ways of increasing the supply of affordable housing for people on low incomes and implementing trials of models of such arrangements. To this end, the Working Group released an issues paper and called for submissions on ways to boost the supply of affordable rental housing through innovative housing models. The consultation process was completed on 6 April 2016.

If the supply of affordable housing is to be increased sufficiently to meet medium- to long-term demand, then this could be met through (among other things) institutional investment in the affordable end of the residential market.

The main barrier to such investment would appear to be that institutional investors have shown relatively little interest in affordable housing, largely due to perceptions of risk and affordable housing’s comparatively low returns. If investors’ reluctance is to be overcome then it is likely that this will require government incentives and the introduction of some form of financial instrument (similar to the discontinued National Rental Affordability Scheme).

The Affordable Housing Working Group is currently considering the merits of a number of such instruments and Australian Housing and Urban Research Institute (AHURI) researchers have undertaken a significant amount of research on Housing Supply Bonds and an Affordable Housing Finance Corporation Model.

Financing instruments such as these could help to increase the supply of affordable housing over the longer term. However, if low-income households currently experiencing housing stress are to gain some respite, then this might suggest the need for a more immediate response. Such a response could include changes to the levels and indexation of CRA to ensure that it better reflects the costs of rental housing, as recommended by the Henry Review of the tax system and the McClure Review of the welfare system.
