Lost Super: The $19 Billion Australians Forgot About

When I moved to Australia, I didn't think much about super. My employer contributes 12%. It's mandatory. It just happens. What's there to worry about?

Turns out, quite a lot.

The Leak Isn't About Contributing. It's About Tracking.

In the US, the retirement leak is about missing your employer match. You have to opt in, and a lot of people don't contribute enough to get the full match. In Australia, the 12% is automatic. Your employer puts it in whether you ask or not.

So the leak here is different. It's not about contributing. It's about knowing where your money actually is.

If you've changed jobs even once, there's a decent chance you have more than one super account. And each one is quietly charging you fees.

How Big Is This Problem?

Roughly 4 million Australians have two or more super accounts. And across the country, there's nearly $19 billion in lost and unclaimed super sitting in accounts that people have either forgotten about or can't locate.

That's not a rounding error. That's billions of dollars doing nothing for the people it belongs to.

Super becomes "lost" when the fund can't contact you and the account hasn't received contributions for 12 months or more. It gets transferred to the ATO. Still your money. Just sitting there earning the ATO's default rate instead of being invested in your chosen fund.

The Quiet Drain

Having two super accounts doesn't feel like a problem. But here's what's actually happening:

Each account charges administration fees. Could be $5-8 a month per account. Each one might have its own insurance policy, with premiums you're paying on coverage you don't need because your current fund already covers you. That's potentially $180-$276 a year in fees you shouldn't be paying.

On a smaller balance, say $12,000 left in an old account, those fees eat 1.5-2.3% of your balance every year. On top of investment management fees. Over a decade, that old account could lose $2,000-$3,000 just to fees and duplicated insurance.

And the compounding works against you too. Money split across smaller balances grows slower than one consolidated balance.

The Fix Takes 10 Minutes

Log into myGov. Link your ATO account if you haven't already. Check for lost super. It shows you every account linked to your tax file number.

If you find old accounts, you can consolidate them into your main fund right there. Roll everything into one place. One set of fees. One insurance policy. Done.

While you're there, it's worth knowing the concessional contributions cap for FY26 is $30,000. That includes what your employer puts in, and it's taxed at 15% inside super. If you're thinking about salary sacrificing, that's the ceiling.

Where This Sits on the Ladder

On the Leak Ladder, super tracking sits at Rung 3, the same rung as employer match in the US. It comes right after your starter emergency fund and before tackling high-interest debt.
