Access to good quality, affordable housing is fundamental to wellbeing. It can help reduce poverty and enhance equality of opportunity, social inclusion and mobility (Gurran et al. 2021; Maclennan et al. 2019). Affordability is important for both Australians wanting to buy a home and for those renting. Many factors influence the supply, demand and cost of housing across the country, including Australia’s growing and ageing population and government policies (AIHW 2021; Burke et al. 2020; Gurran et al. 2021).
Housing affordability typically refers to the relationship between expenditure on housing (prices, mortgage payments or rents) and household incomes (Thomas & Hall 2016). Home ownership and housing tenure and Housing assistance are related to housing affordability.
Measuring housing affordability is not straightforward. A household’s financial situation, the overall demand in the housing market and housing tenure type (whether a household is seeking to rent, is renting, is looking to buy or is a home owner with or without a mortgage) all influence individual housing affordability (Senate Economics References Committee 2015). The simplest measure of housing affordability compares housing costs to gross household income.
Housing affordability can be expressed as the ratio of housing costs to gross household income (ABS 2019).
Housing costs are defined as the sum of rent payments, rate payments (water and general), and housing–related mortgage payments (ABS 2019).
Housing stress is typically described as lower-income households that spend more than 30% of gross income on housing costs (ABS 2019).
In 2017–18, 11.5% of households spent 30% to 50% of gross income on housing costs with another 5.5% spending 50% or more (ABS 2019). These proportions have increased from 9.2% and 4.6% respectively since 1994–95 (Table 1).

Estimates presented from 2007–08 onwards are not directly comparable with estimates for previous cycles due to the treatment of incomes. See ABS 2019 for more details.

The proportion of household income spent on housing costs in Table 1 does not consider that high-income households may choose to spend more than 30% of their household income on housing. Their higher income means they have sufficient income after housing costs to avoid financial stress (AHURI 2018; Rowley et al. 2015).
By contrast, low-income households (lowest 40% of household income distribution) are more likely to lack the resources to deal with financial impacts arising from critical life events and/or housing market factors, often leading them to need additional housing assistance (AIHW 2021).
The 30/40 housing stress rule focuses on low-income households. These are defined as lower-income households (lowest 40% of income; see glossary) that spend more than 30% of gross household income on housing costs. They are considered to be in financial housing stress (Rowley et al. 2015; Yates 2007).
Over 1.0 million low-income households were in financial housing stress in 2017–18, based on the 30/40 rule (ABS 2019). Households with low income in the private rental market were more likely to be in housing stress, spending on average 32% of income on housing costs, compared with home owners with a mortgage (29%) or home owners without a mortgage (6.0%) (Table 2). Of household compositions, lone person households on average spent the highest proportion of income on housing costs.

Due to limitations of housing costs information, care should be taken when comparing costs of different tenure and landlord types.
Housing costs as a proportion of gross household income is the sum of housing costs of a group divided by the summed gross weekly income of that group in households.
Housing costs and incomes varies across Australia, meaning housing affordability differs within and between states and territories and among housing tenure types (for example, home owners with a mortgage or renters).
In 2017–18 (Figure 1):
This column graph shows the housing costs as a proportion of gross income for owners without a mortgage, owners with a mortgage, renters from state/territory housing authorities, renters private landlords and total.
This column graph shows that housing costs as a proportion of gross household income are highest in Queensland at 14.8%. Housing costs as a proportion of gross household income are 13.7% for New South Wales, 14.0% for Victoria, 13.6% for Western Australia, 13.2% for Northern Territory, and 13.9% for the total of Australia. The Australian Capital Territory (12.5%), South Australia (12.4%), and Tasmania (11.7%) are lowest.

For low-income households in the private rental market, the proportion in rental stress (based on the 30/40 rule) varies between the capital cities and the rest of the states and territories. The gap between these areas has increased over time (ABS 2019) (Figure 2):
This column graph shows the proportion of low income households in greater capital cities, the balance of the states and territories and all households spending more than 30% of their gross income on housing cost for the years 2007–2008, 2009–2010, 2011–2012, 2013–2014 and 2015–2016.
This column graph shows that the proportion of low income households in greater capital city areas spending more than 30% of their gross income on housing costs increased between 2007–08 and 2017–18 from 38.5% to 47.8%. The proportion of low income households in rest of state areas spending more than 30% of their gross income on housing costs also increased between 2007–08 and 2017–18 from 29.5% to 35.6%. The proportion of all low income households spending more than 30% of their gross income on housing costs increased between 2007–08 and 2017–18 from 35.0% to 43.1%.

The rental affordability index (see glossary) is a price index for housing rental markets across geographical areas of Australia, calculated using median incomes. A rental affordability index score of 80–100 represents unaffordable rent (that households spend 30 percent or more of their income on rent), a score between 100 and 120 represents moderately unaffordable rent, a score between 120 and 150 represents acceptable rent and a score greater than 150 represents affordable rents (SGS Economics and Planning 2020).
In general, rental affordability index scores are worse for metropolitan areas compared with the rest of the state or territory. As at June 2020:
Very low income households continue to face unaffordable rent in most capital cities (Hulse and Nygaard 2020).

The experience of tenants in the private rental market is increasing in importance as more households are renting, and for longer periods. The proportion of Australian households renting has increased, from 22% (1.5 million households) in 2006 to 27% (2.1 million households) in 2016 (ABS 2019). Some household demographic factors, household composition factors and personal factors that affect the demand for private rental housing include:
Many renters find their housing to be insecure, of poor quality and unaffordable. In 2018, 44% of renters were concerned that a request for repairs could result in an eviction and 68% were worried they would face rent increases if they complained about the low quality of their housing or asked for repairs (CHOICE et al. 2018).
Many leases in Australia last for one year and some for just six months or less. This results in tenants moving more frequently than home owners. By contrast, Denmark, Germany, and the Netherlands have indefinite and fixed-term leases where it is difficult to terminate the fixed-term lease without the tenant’s permission (CHOICE et al. 2017). In Australia in 2018:
Households experiencing rental stress and/or unable to access the private rental sector may be at risk of homelessness (AIHW 2020). Further, households with low income may find it difficult to compete with higher-income households in the private rental market and may therefore seek assistance with housing costs or to rent a social housing property. See Housing assistance for more information.
Although the true effects of COVID-19 pandemic are still emerging, analyses based upon a report conducted in mid-2020 showed that there was widespread impact on the experiences of Australian renters in the private rental market. The report indicated that peoples employment, ability to pay rent, living environment and risk of eviction were affected (Baker et al., 2020a). Since the beginning of the pandemic in 2020:
Several changes in the Australian housing market can be linked to the onset of the COVID-19 pandemic in early 2020. The private rental market was especially affected during 2020 where there have been dissimilar trends between Perth and the eastern capital cities, regional areas and inner cities, and units and houses (Pawson et al. 2021).
Several changes have occurred in the private rental market due to the pandemic including:
Prior to the COVID-19 pandemic, the size of the private rental market increased from 24% of all households in 2009-10 to 27% in 2017-18 (Pawson et al. 2021). Since the COVID restrictions were introduced, the supply of long-term rental accommodation increased due to the transition of accommodation in the short-term market and newly completed dwellings becoming available. In the future, some of these dwellings may transition back to the short-term market due to the increase in domestic tourism and business travel (Evans et al. 2020).
Prior the COVID-19 restrictions, from 2013-14 to 2015-16, the majority of new dwellings that were built in Sydney, Melbourne and Brisbane consisted of flats, units and apartments rather than separate houses. These were largely built in the middle and inner part of these cities (ABS 2021a). In 2020, the supply of these rental properties increased, especially in high-density areas, as new buildings were completed (Pawson et al. 2020)
Changes in visitor and international student numbers
As a result of international border closures, from January to December 2020, international visitor numbers decreased by 89%. With decreases in international tourism, many short-term rental accommodation dwellings such as Airbnb were moved into the long-term rental market, increasing the supply of rental accommodation (Pawson et al., 2021). For example, Airbnb accommodation decreased by 14% in Sydney and 22% in Hobart and Melbourne from March and April 2020 (Buckle et al. 2020; Pawson et al. 2021).
There was also a decline the number of international students arriving in Australia. Only 230 students arrived in Australia in March 2021; a decrease of around 60,100 students compared with March 2020 (ABS 2021b). Since international students are more likely to live in inner cities and in apartments than domestic students, the rental market in metropolitan areas of capital cities were more affected, especially in Sydney, Melbourne and Brisbane (Pawson et al. 2021).
Decreases in rental prices
With an increase in the availability of rental properties in some capital cities, there was a corresponding decline of median rents for inner city apartments. In north and west Melbourne, for example, median rents declined around 5% between quarters one and three of 2020. Sydney experienced declines of up to 10%. Inner city high-density areas were more affected, especially in Sydney, Melbourne and Hobart (Buckle et al. 2020; Pawson et al. 2021).
Due to the movement of people to outer metropolitan and regional areas, a number of outer metropolitan and regional areas have experienced a decrease in the supply of accommodation in the private rental market. There has also been an increase in the demand of accommodation in the private rental market in these areas (Pawson et. al. 2021). This has led to increases in prices of dwellings in these regions. This can be attributed to significant changes in housing preferences, with more Australian’s preferring to live in larger dwellings that are better suited for working from home and leisure activities (Stone et al. 2020a, 2020b).
A decline in the cost of rent does not make rents more affordable for all Australians since affordability is based on household income. The income of renters has decreased more than rental prices since renters have been more affected by the pandemic than homeowners. From March to June 2020, housing cost fell by 0.5% while the income of renters decreased by 5%. By comparison, housing costs decreased by 5% and incomes fell by 0.2% for homeowners with a mortgage (Pawson et al. 2021).
