$21.5B in Lost Super: How to Find Lost Superannuation Fast 🇦🇺
Australians are leaving $21.5B in unclaimed superannuation earnings in forgotten accounts, and the ATO says checking takes just minutes through myGov or by phone.
The number that matters
The central number is $21.5B of unclaimed superannuation earnings sitting in forgotten accounts, reported by the Australian Treasury in 2025.
How it quietly costs you
The first hidden cost is multiple small super accounts that stay open after job changes, so fees and insurance can keep eroding balances instead of being consolidated into one account.
The ATO and major funds explain that lost super typically sits either with a previous fund or with the ATO, and funds may classify an account as lost when they cannot contact the member and no contribution or rollover has been received for a specified period.
The quantified impact is real at scale: the Treasury says there were about 7.3M accounts with unclaimed super and the typical amount of lost super was about $2,950 per account in 2025.
The “old vs better” comparison is:
- Old: leave the account fragmented and forgotten, so balances can be eaten by ongoing fees and insurance.
- Better: consolidate or claim it through ATO online services or your fund’s search tool, which the ATO says takes just minutes.
The second, compounding trap
A second layer is ATO-held super that is not automatically paid out unless the member checks details and applies where eligible, so money can sit idle even after it has already been transferred out of a fund.
The ATO says former temporary residents may have super transferred to the ATO after 6 months of leaving Australia or visa expiry/cancellation, and that eligible people must use ATO online services to update details and apply to withdraw ATO-held super.
The long-run cost of inaction is losing access to balances for years; Treasury’s 2025 figures imply that millions of accounts are affected and that the problem is not trivial “found money,” but a large stock of dormant balances averaging roughly $2,950 each.
The mechanism is:
- funds report certain accounts as lost;
- the ATO receives the money;
- the member must check, update details, and lodge the withdrawal or consolidation step themselves.
What this looks like in practice
Mia, 34, retail supervisor, income $68K, 3 super funds, $11,400 total balance, 31 years to retirement.
She would discover:
- She likely has more than one account because the ATO says lost super is often sitting with a previous fund or with the ATO, and consolidation can be done through myGov in minutes.
- Her forgotten balance could be meaningful: the Treasury says the typical lost-super amount is $2,950, which is a large share of a worker’s balance when split across accounts.
- The cost of not acting is ongoing fragmentation: funds may classify an account as lost after no contribution or rollover for a period, meaning fees and insurance can continue without the member noticing.
The full cost of doing nothing
For Mia, if she leaves a $2,950 forgotten account untouched and separately keeps multiple accounts open, the combined career cost can compound through duplicate fees and delayed consolidation over 31 years.
A conservative modelling basis is:
- one forgotten account of $2,950 today;
- continued fee drag from an extra account until consolidation;
- long time horizon to retirement of 31 years.
The headline is that a single missed account can plausibly cost thousands of dollars now and more over decades through compounding fee drag, with the exact amount depending on fund fees and insurance settings.
What to do about it
- Check your super in myGov / ATO online services under Super → Fund details.
- Sign in to myGov linked to the ATO.
- Open Super and review all listed accounts.
- Note any lost, active, or ATO-held super.
- Good looks like one active account and no stray balances.
- Call the ATO lost super search line on 13 28 65 if you want a fast phone check.
- Have your TFN ready.
- Follow the automated prompts to search for super.
- Record any fund names and balances.
- Good looks like identifying every account you own and confirming where each balance sits.
- Consolidate or withdraw through the correct portal once you confirm the account status.
- If the money is in a super fund, use the fund’s consolidation pathway.
- If the money is ATO-held super, go to Super → Manage → Withdraw ATO-held super in ATO online services if eligible.
- Update your financial institution details first so payment goes to the right account.
- Good looks like one account, correct bank details, and no unclaimed balances left behind.
A myth worth clearing up
Myth: “If I change jobs, my super follows me automatically.” Fact: Super can be left behind in a previous fund or transferred to the ATO as lost or unclaimed super, so you still need to check and consolidate it yourself.
