For years, self-managed super funds were seen as the preserve of older, wealthier Australians nearing retirement. That picture is changing fast. In the six months to 31 December 2025, Millennials and Gen X together made up 90.3 per cent of new SMSF establishments. As at September 2026, the typical new Trustee is decades younger than the sector's traditional face, and the reasons are as much cultural as financial.

A generation raised on compulsory super

Part of the story is timing. Compulsory Superannuation has existed in Australia since the early 1990s, meaning younger workers have never known a working life without it. Their super balances have grown large enough to make self-management feel worthwhile, and they have grown up treating super as their money to manage.

As one industry association executive put it, for anyone under 50 in the workforce, compulsory superannuation has been a constant throughout their working life.

That lifelong familiarity appears to translate into engagement. Rather than viewing super as a distant, set-and-forget account, many in this cohort want to understand and optimise their balances.

The numbers behind the shift

The demographic change is striking. Data shows the average age of a new trustee is now 47, compared with 61 for existing trustees. Australian Taxation Office figures indicate those aged under 50 account for nearly 70 per cent of new SMSFs, and the 35 to 44 age group has become the single largest demographic entering the sector.

By contrast, in the existing SMSF population, 85 per cent of members are aged 45 or older, highlighting just how much younger the new entrants are.

Digital engagement and a desire for control

This is a generation comfortable managing money through apps and online platforms, and that digital fluency lowers the perceived barrier to running a fund. Contemporary administration software handles much of the record-keeping and reporting that once required an accountant's constant involvement.

Tellingly, around 80 per cent of newly established SMSFs were set up without financial advice. Whatever the merits of that trend, it suggests many younger Australians are actively researching and choosing self-management themselves rather than being guided into it.

A desire for control sits alongside this. Running an SMSF allows members to choose specific investments, from Australian shares and Exchange-traded funds to, in some cases, property, and to align their super with their own preferences.

Structure and responsibility

The new cohort is also doing things differently in practice. Around 98 per cent of new establishments use a corporate trustee structure, which can simplify administration and succession compared with individual trustees.

Enthusiasm, however, comes with obligations. Every trustee is personally responsible for complying with super and tax law, meeting the sole purpose test, keeping fund money separate from personal money, maintaining an Investment strategy and arranging an annual independent audit. An SMSF can have up to six members, and all are generally trustees or directors of the corporate trustee.

A cultural turning point

The arrival of a younger, digitally-engaged and super-native generation marks a genuine cultural shift for the sector. These Australians are drawn by control, engagement and the confidence that comes from a lifetime alongside compulsory super. Whether an SMSF suits any individual still depends on their circumstances, and the responsibilities are significant. For a growing number of younger investors, though, taking the reins of their retirement savings has clearly become an appealing idea.
