A self-managed super fund (SMSF) is a type of super fund where the members are generally also the trustees, or directors of the corporate trustee, and are responsible for managing the fund.
SMSF trustees are responsible for making investment decisions and ensuring the fund complies with superannuation and tax laws.
Setting up an SMSF involves things such as:
An SMSF can give you greater control over how your super is managed and invested, but it also comes with costs, risks and responsibilities.
As a trustee, you’re responsible for managing the fund and ensuring it complies with superannuation and tax laws. It’s important to understand both the potential benefits and the responsibilities involved before deciding whether an SMSF is right for you.
Before initiating a rollover from an APRA-regulated fund (like an industry or retail super fund), the SMSF should meet several requirements:
Once these are in place, you can request a rollover from your existing fund.
Before initiating a rollover, review any existing insurance policies and other benefits. These do not automatically transfer to your SMSF, so you may need to arrange new cover separately.

SMSFs can invest in a range of assets, subject to superannuation laws and the fund’s investment strategy. These may include cash, Term Deposits, shares, ETFs and property.
As a trustee, you’re responsible for ensuring your fund’s investments comply with the relevant rules and your SMSF’s investment strategy.
SMSFs are complex and involve legal, administrative and compliance responsibilities. SMSF trustees (or directors of a corporate trustee) are responsible for managing the fund and ensuring it complies with all applicable requirements such as superannuation, tax and trustee obligations.
