These Sydney suburbs are among the richest in Australia right now

There’s something both fascinating and faintly exhausting about reading lists of Australia’s richest suburbs. On one hand, it’s pure escapist indulgence; on the other, it’s a reminder that for most of us, a harbourside mansion with a private jetty is about as attainable as a casual swim to New Zealand. Anyway, if you’re curious, the 10 richest suburbs in Australia have dropped – and yes, Sydney is still home to some impossibly wealthy pockets. 

Fresh data from the Australian Taxation Office (ATO) has revealed the country’s highest-earning postcodes, and while a Victorian seaside enclave has pinched the top spot, NSW still dominates the leaderboard.

Based on the stats, Bellevue Hill has landed in third place, with an average taxable income of $250,899. Just down the road, the 2030 postcode – covering Vaucluse, Dover Heights, Rose Bay and Watsons Bay – comes in fourth. Then there’s postcode 2027 (Darling Point, Point Piper and Edgecliff), which has slipped to sixth after topping the list last year. Even in “decline”, the average income here sits at a casual $238,954. Point Piper, in particular, is often cited as Australia’s most expensive suburb – all waterfront estates and discreet wealth – while Edgecliff offers a rare (and relative) entry-point for apartment dwellers looking for a slice of eastern subs life. Woollahra (2025) also makes the cut – a leafy pocket of the city with big change on the way (more on that here).

Over on the lower north shore, Hunters Hill and Woolwich (2110) rank eighth. These suburbs swap surf for serenity, with heritage homes, riverside views and a quieter, almost village-like atmosphere. Mosman (2088) rounds out the NSW contingent in tenth place, with an average income just north of $208K. And finally, Double Bay (2028) – often dubbed Sydney’s answer to the French Riviera – slides into ninth.

Of course, zoom out from these postcodes and the picture shifts pretty quickly. The national average income sits at $74,727 – a figure that feels galaxies away from the numbers above. While these suburbs might dominate headlines (and real estate fantasies), they represent a very small, very rare slice of Australian life.

Still, if nothing else, the list offers a bit of escapism – and maybe a reminder that Sydney’s real charm isn’t just in its most expensive corners, but in the diverse, actually-liveable neighbourhoods the rest of us call home.
