Postcode-level figures on this page are sourced from the ATO's Lost and Unclaimed Super by Postcode dataset, most recently published with data as at 30 June 2020. Whole-of-Australia totals continue to be updated annually — the most recent national figure is $18 billion as at 30 June 2025. Account counts and dollar values shown here may have changed since June 2020 as people have consolidated or claimed their super.
Australians lose track of billions in superannuation every year. When you change jobs, move house, switch funds, or change your name without updating contact details, your super can become "lost" — still held by a fund or transferred to the ATO, but disconnected from you. The ATO publishes the breakdown by postcode so people can see roughly how much money is unclaimed in their area.
Log into MyGov, link the ATO, and search for super under your TFN. It takes less than 5 minutes. Read our complete guide for step-by-step instructions including how to handle super from deceased estates and former temporary-resident accounts.
