The Australian Taxation Office (ATO) analysed 14.7 million individual tax returns from the 2018-19 income year, finding the postcodes with the highest and lowest average taxable incomes.

Sydney’s harbourside suburb of Double Bay took out the top spot, with 3,573 individuals reporting an average taxable income of $202,541.

Melbourne took out two spots in the richest suburbs list as well – Hawksburn/Toorak and Portsea – while Western Australia snuck one in with Perth’s beachside neighbourhood, Cottesloe.

On the other end of the scale, the New South Wales regional towns of Burren Junction and Drildool, which have both been ravaged by drought, reported the lowest taxable incomes – no taxable income, in fact. Their postcode, 2386, actually recorded an average loss of $9,735 for income tax purposes.
