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.
Lost vs unclaimed split
The ATO categorises this two ways. Lost (fund-held) super is held by your super fund but they've lost contact with you (e.g. uncontactable for over five years). Unclaimed (ATO-held) super has been transferred to the ATO because the fund couldn't reunite it with a member — typically smaller balances, inactive low-balance accounts, and super for former temporary residents. Both can be reclaimed through MyGov.
| Category | Accounts | Total Value | Avg |
|---|---|---|---|
| Lost (fund-held) | 65 | $2M | $23,241 |
| Unclaimed (ATO-held) | 575 | $355,620 | $618 |
| Total | 640 | $2M | $2,916 |
The ATO's most recent national figure is $18 billion in lost and ATO-held super as at 30 June 2025. It takes less than 5 minutes to check whether any of it is yours through MyGov.
How to find your lost super (5 steps)
If you've lived or worked in Castlemaine (3450) — or anywhere else in Australia — these are the steps:
Log into MyGov
Go to my.gov.au and sign in (or create an account if you do not have one). You will need your email, mobile, and a form of ID.
Link the ATO
From your MyGov dashboard, link the Australian Taxation Office (ATO) service. You will need your tax file number (TFN) and details from a recent tax return or ATO correspondence.
Search for lost super
In the ATO portal, go to Super > Manage > Find lost super. The system will show any super accounts linked to your TFN, including accounts you may have forgotten about. Both lost (fund-held) and unclaimed (ATO-held) super show up here.
Consolidate your accounts
If you find multiple accounts, you can consolidate (combine) them into your chosen fund directly through the ATO portal. Select the accounts to transfer and confirm. This usually takes 3-5 business days. Before consolidating, check whether any of your accounts have insurance you'd lose by closing them.
Update your employer
Give your employer a Superannuation Standard Choice Form with your chosen fund's details so future contributions go to the right place. This prevents new lost super from accumulating.
Our complete guide to finding lost super covers edge cases — what to do if your super was sent to the ATO, how to handle super from deceased estates, and how to choose the best fund to consolidate into.
Why lost super accumulates
Lost super builds up when fund members lose contact with their fund. The most common causes are changing jobs without updating fund details, having multiple accounts from casual or part-time roles, employer contributions to a default fund the member did not actively choose, and name or address changes that break the link between the member and the fund. Once a fund is unable to reach a member for an extended period (typically five years), the account is classified as lost. Inactive low-balance accounts may then be transferred to the ATO for safekeeping under unclaimed super provisions.
