Interactive Map Reveals Shifting Wealth Landscape in Australian Suburbs

An interactive wealth map of Australia has revealed a significant shift in the nation's affluence, with previously overlooked suburbs now outearning traditional wealthy enclaves. The data, compiled from tax returns, challenges long-held perceptions of where Australia's highest earners reside. Traditional powerhouses like Sydney's eastern suburbs and Melbourne's leafy east, alongside Perth's Golden Triangle, have long defined the country's wealth map. However, new economic corridors are emerging, driven by factors such as improved transport links and access to high-paying professional jobs.

KPMG urban economist Terry Rawnsley noted that these evolving wealth belts now command million-dollar price tags, largely due to an influx of high-income professional families. This trend is particularly evident in Sydney's northwest, where suburbs like Kellyville have seen substantial growth.

Canberra's inner south has also emerged as a new hub of wealth.

These areas, along with Double Bay and Darling Point, and Canberra's inner south, represent some of the highest-ranking areas by median income.

Conversely, some popular holiday destinations, such as Portsea, which attracts Melbourne's affluent residents and boasts high median house values, do not necessarily reflect the average taxpayer's income. While Portsea has a high average taxable income, the typical earner's income is significantly lower, indicating that a small number of extremely wealthy individuals can skew the overall average. IMAGE2 While Portsea - a popular holiday destination for Melbourne's moneyed set, including Bec and Chris Judd - might boast Australia's highest average taxable income and a median house value approaching $2.5million, the typical taxpayer earns just $75,808 a year, highlighting how a relatively small group of ultra-wealthy residents can dramatically skew average income figures The notes also point to significant property transactions, such as swimming legend Grant Hackett's purchase of a Toorak mansion for $13.4 million.
