Lost superannuation in Australia: how to find it, and how to make sure your family does not lose yours

As of June 2025, the Australian Taxation Office holds or is tracking around $18.9 billion in lost and unclaimed superannuation — money that belongs to real Australians who, for one reason or another, have lost the trail.

Some of that money is small (the leftover balance from a casual job in your 20s). Some of it is significant (an account that has been compounding quietly for two decades). All of it is real, and most of it is recoverable in less than thirty minutes.

How super goes "lost" in the first place

Lost super is usually nothing more dramatic than a postal address that never got updated. There are three main ways it happens:

• You changed jobs and a new fund was opened by your employer. Until the introduction of "stapling" in 2021, every new employer typically opened a default account. If you started six jobs in your career, you may have six funds — each charging admin fees against a small balance.
• You moved house and your fund could not contact you. Funds are required to report accounts as "lost" to the ATO when two pieces of returned mail come back undelivered, or when an account has been inactive for a defined period.
• Your account was transferred to the ATO. Once an account has been inactive for an extended period with a low balance, the trustee must transfer the balance to the ATO for safekeeping. Your money still belongs to you — but it now sits with the Commissioner, not your fund.

How to find yours, in about ten minutes

The easiest path is through myGov:

1. Log into myGov and link the ATO service if you have not already.
2. Open "Australian Taxation Office" then choose "Super" from the main menu.
3. Open "Manage" → "Find my super". The ATO will show every super account it has on record for you, including any held directly with the ATO.
4. From the same screen you can request to consolidate accounts — but read the next section before you do.

Consolidating super: faster, but read this first

Combining multiple super accounts into one usually saves you money — fewer sets of admin fees, less complexity, easier to track returns. But there are three things to check before you press the button:

1. Insurance inside super

Many default super accounts come with bundled life insurance, total and permanent disability (TPD) cover, and/or income protection. When you close an account, that cover usually ends — and you may not be able to get it back if your health has changed. If you have insurance you care about inside an old fund, transfer the insurance to your destination fund first, or keep the old account open until you have arranged equivalent cover elsewhere.

2. Exit fees and tax

Most modern super funds have abolished exit fees, but some legacy funds still charge them. Some products (particularly some retail funds and a few SMSFs) may also create capital gains tax events when assets are sold to make a transfer. For most people, on most accounts, this is negligible — but check the product disclosure statement before a large transfer.

3. Where you are transferring to

Don't simply pick the largest of your accounts. Compare administration fees, investment fees, insurance availability, and long-term performance. The fund you keep is the one you will be paying every year for the rest of your working life — make it the best one you have.

The other half of the problem: your family losing your super

Lost super is not just a problem for the living. When someone dies in Australia, their super does not automatically follow their will. The trustee of the super fund decides who receives the death benefit — unless the deceased had a valid Binding Death Benefit Nomination in place.

This is the section nobody talks about enough. Two practical points:

• BDBNs typically expire every three years. Unless you have one of the newer "non-lapsing" nominations, you need to renew yours regularly. Otherwise the trustee discretion kicks back in.
• BDBNs can only name "dependants" under the SIS Act. Your spouse, children, financial dependants, and people in an interdependent relationship with you. Adult children are eligible. Your favourite niece, your best friend, or a charity are not (unless they qualify under one of the SIS categories) — for them, the super must go to your estate first, then be distributed under your will.

Reversionary pensions for spouses

If you are already drawing a pension from your super (the "retirement phase"), you may have the option to nominate a reversionary beneficiary — usually your spouse. When you die, the pension automatically continues in their name, with minimal disruption. This is generally faster, simpler, and more tax-efficient than the alternative of paying out a lump sum to the estate and then re-establishing income.

Reversionary pensions are a specialist area — talk to your fund and, if your situation is complex, a licensed financial adviser. But it is worth knowing the option exists.

What your family will need to find

If your super is well-organised, your family or executor will need to know:

• The name of each fund.
• Your member number with each fund.
• The fund's contact details (claims phone line, claims email).
• Your most recent statement (helps establish balance and product).
• Your current Binding Death Benefit Nomination (or where to find a copy — the fund will have the authoritative version).
• Whether you have a reversionary nomination on any pension.
