Why more Australians on high incomes are renting

There has been a substantial increase in the number of Australians earning high incomes who are renting their homes instead of owning them, and this may be another element contributing to higher market demand and continually rising rents, according to new research.

The portion of households with an annual income of $140,000 per year (in 2021 dollars), went from 8 percent of the private rental market in 1996 to 24 percent in 2021, according to research by the Australian Housing and Urban Research Institute (AHURI). The AHURI study highlights that longer-term declines in the rate of home ownership in Australia are likely the cause of this trend.

The biggest challenge this creates is the flow-on effect on lower-income households because they may face stronger competition for a limited supply of rental stock, and they also have less capacity to cope with rising rents that look likely to keep going up due to the entrenched undersupply.

The 2024 ANZ CoreLogic Housing Affordability Report notes that weekly rents have been rising strongly since the pandemic and are currently re-accelerating. “Nationally, annual rent growth has lifted from a recent low of 8.1 percent year-on-year in October 2023, to 8.6 percent year-on-year in March 2024,” according to the report. “The re-acceleration was particularly evident in house rents, where annual growth bottomed out at 6.8 percent in the year to September, and rose to 8.4 percent in the year to March 2024.”

Rents are also rising in markets that have experienced recent declines. “In Hobart, rent values saw a downturn of -6 percent between March and October 2023. Since bottoming out in October, rents have now moved 5 percent higher to the end of March, and are just 1 percent off the record highs in March 2023. The Canberra rental market was the only other capital city to see a decline in rents in recent years, where rent values fell -3.8 percent between June 2022 and September 2023. Since then, Canberra rents have risen 3.5 percent, and are 1 percent from the record high.”

The Productivity Commission’s review of the National Housing and Homelessness Agreement points out that high-income earners also have more capacity to relocate to cheaper markets when rents rise, which creates more competition for lower-income households competing for homes in those same areas.

ANZ CoreLogic notes that rents in lower-cost markets have risen the most in recent years, so much so that the portion of earnings that lower-income households have to dedicate to rent has reached a record high 54.3 percent. For middle-income households, it’s 32.2 percent and for high-income households, it’s just 22.9 percent. ‘Housing stress’ has long been defined as requiring more than 30 percent of income to put a roof over your head.

While some high-income households may aspire to own their own homes, rising property values have made that a difficult and long process given the years it takes to save a deposit. ANZ CoreLogic data shows it now takes a median 10.1 years in the capital cities and 9.9 years in regional areas to save a 20 percent deposit to buy a property.

It also takes 48.3 percent of income in the cities and 47.1 percent in the regions to cover mortgage repayments at today’s home loan interest rates, which is far greater than the portion of income required to service rents at a median 30.4 percent in cities and 33.3 percent in the regions.

Australia’s major CBD office markets are recording some of their strongest rental growth since the pandemic, with businesses increasingly prioritising premium office space despite elevated geopolitical and economic uncertainty.

Knight Frank’s Australian Office Indicators Q1 2026 report found net effective rents in Sydney and Melbourne CBDs rose at their fastest annual pace since COVID-19, increasing 10.2 per cent and 6.8 per cent respectively over the 12 months to March.

Brisbane posted the strongest growth nationally, with net effective rents climbing 11.7 per cent over the same period.

The report points to a widening divide between prime CBD office towers and secondary office stock, as occupiers increasingly focus on quality, location and workplace amenity when making leasing decisions.

Knight Frank Senior Economist, Research & Consulting Alistair Read said demand remained heavily concentrated in premium assets within core CBD precincts, helping drive stronger rental growth in top-tier buildings.

“Occupier demand continues to be heavily concentrated in the most desirable CBD precincts and the highest-quality buildings, accelerating a sharp divergence between core and non-core markets,” Mr Read said.

According to the report, Sydney’s Core precinct and Melbourne’s Eastern Core significantly outperformed broader CBD markets over the past year.

“In Sydney’s Core precinct and Melbourne’s Eastern Core, net effective rents surged 14.3% and 16.1% over the past year, significantly outperforming the rest-of-CBD precincts,” Mr Read said.

The rental gap between prime and non-prime office locations has also continued to widen sharply.

“As a result, core CBD rents are now 54% higher than non-core locations in Sydney and 93% higher in Melbourne, highlighting the growing premium placed on amenity, accessibility and workplace quality,” he said.

Knight Frank said the strong rental growth across the major CBDs was being underpinned by a limited supply pipeline, with few new office developments expected to be delivered in the near term.

Mr Read said subdued construction activity was likely to support ongoing rental growth and tighter vacancy rates over the medium term, particularly for premium office towers.

“The combination of sustained demand and declining levels of new development will aid ongoing prime rental growth and lower vacancy rates over the medium term, particularly for best-in-class assets,” he said.

The report noted that current economic conditions were making new office developments increasingly difficult to justify financially.

“Economic rents remain well above expected market rents, making the construction of new office towers largely unviable, and concentrating tenant demand into existing buildings,” Mr Read said.

While suburban office markets generally remained subdued compared with CBDs, Melbourne’s Southbank precinct was identified as a relative outperformer, recording annual net effective rental growth of 2.7 per cent.

The report comes as broader Asia-Pacific office markets continue to stabilise following several years of disruption linked to hybrid work trends, inflation and rising interest rates.

Knight Frank’s separate Asia-Pacific Q1 2026 Office Highlights report found Sydney and Brisbane were among the strongest-performing office rental markets in the region, behind only Bengaluru and Tokyo for annual prime net face rental growth.

The Asia-Pacific report also found 18 of the 24 cities monitored across the region recorded stable or increasing rents in the first quarter of 2026, even as geopolitical uncertainty intensified following escalating conflict in the Middle East.

This may be contributing to continually rising weekly rents

Office rents in Sydney, Melbourne and Brisbane are climbing at their fastest pace since the pandemic as tenants compete for premium CBD space amid tightening supply.
