Latest data shows six of Australia’s 10 highest-earning postcodes are located in Sydney, while four of the lowest-earning postcodes are in regional Queensland.
Each year, the Australian Taxation Office (ATO) undertakes a survey of tax return data from around the country, to give a snapshot of earning patterns, including areas of highest and lowest income. The most recent survey data, from the 2021-2022 financial year, analyses the tax returns of 15.5 million Aussies, finding the richest postcodes with the highest average taxable income, as well as the poorest postcodes with the lowest average taxable income.
The New South Wales suburb of Double Bay took out the top spot as the richest suburb in Australia, with data from the ATO showing that residents in the 2028 postcode had an average taxable income of $354,308. This is almost five times more than the national average of $72,327.
The richest postcodes list was mostly dominated by affluent areas of Sydney, however, Western Australia’s 6011 postcode (which includes Cottesloe and Peppermint Grove) came in second with an average income of $295,283. This was followed by the 2027 postcode (which includes Darling Point, Edgecliff, HMAS Rushcutters and Point Piper) with an average income of $230,597.
For the poorest postcodes, Newcastle’s 2308 postcode, (which includes Callaghan and Newcastle University) reported the lowest average taxable incomes of $20,878. The 2052 postcode, which covers the University of New South Wales, was the second lowest with an average income of $20,892. This top two seems skewed by being in areas where most of the population are either studying or working lower paying casual or part time jobs, as many university students tend to do. In third place was the South Australian postcode of 5308, about two hours east of Adelaide (which includes Copeville, Galga, Mantung, Mercunda and Perpond). It had an average income of $21,049.
