Consolidation and rise of the superannuation mega-funds

Australia's superannuation industry is rapidly becoming an industry of mega-funds.

APRA's latest fund-level statistics show the number of regulated funds in the dataset has fallen from 130 in June 2021 to just 66 in June 2026 — almost exactly halving in five years.

But the money has moved in the opposite direction.

Member benefits increased from $2.14 trillion to $3.20 trillion, while the average amount of member benefits per fund almost tripled from $16.5 billion to $48.4 billion.

The largest funds are becoming particularly powerful institutions. AustralianSuper now has $438 billion in member benefits and Australian Retirement Trust $366 billion. Together they account for about a quarter of the market captured by these statistics.

The top five funds now hold 42.8 per cent of member benefits, up from 32.0 per cent in 2021. The top ten control 60.5 per cent.

There are good reasons for consolidation. Larger funds can spread administration, technology and compliance costs across millions of members and have greater bargaining power when purchasing investment-management services.

But scale also changes the structure of Australia's financial sector.

Trustee boards overseeing hundreds of billions of dollars make increasingly consequential decisions about which asset managers receive mandates, which infrastructure and private-market assets receive capital, which technology providers are selected and which professional advisers are engaged.

For asset managers, winning or losing one mega-fund mandate can therefore matter enormously. For investment consultants, financial advisers, lawyers, technology companies and other advisory businesses, there are also fewer — but much larger — institutional clients.

That makes expertise important, but also professional connectivity. Firms wanting to participate in Australia's growing superannuation system increasingly need strong relationships, reputations and networks inside a relatively small number of very large funds.

Australia has not simply consolidated its super industry.

It has created a new class of extremely powerful financial institutions.
