Mainstream Superannuation Services provides member administration, unit pricing and accounting services to industry funds, corporate superannuation funds and retail superannuation master trusts.

For over 15 years Mainstream Superannuation Services has successfully administered corporate, master and industry superannuation funds.

Our story began in 1999 when Group Benefits was established by a group of former executives of The Australian Superannuation Group. In 2007 Group Benefits was acquired by Mainstream before being renamed SuperBPO in 2011, and renamed Mainstream Superannuation Services in 2017.

Today we are a leading independent specialist in superannuation. We offer a personalised end-to-end service for funds that wish to outsource all or part of their administration requirements.

We have experience in managing all aspects of a superannuation fund including:

  • Accumulation funds
  • Defined benefit funds
  • Hybrid funds
  • Account based pensions and transition to retirement pensions
  • Existing fund takeover – transition management
  • Mapping of member data between systems
  • Communication to members
  • New fund establishment
  • Benefit design consultation
  • Product Disclosure Statement design and production
  • Communication programs


We pride ourselves on offering flexible, tailored solutions. You can choose the services you need:


Tailored service to fit your fund

We can create a service solution that meets your needs, rather than asking you to fit our model. Choose from a full service model or a stand-alone service.

Dedicated experts running your administration

Backed by Mainstream Group Holdings, we are financially secure, giving you peace of mind. We have minimal staff turnover and our employees are dedicated to administration; that is all we do.

Better technology for better decision making

Access the industry’s leading technology without incurring long term expenditure. Stay on top of legislative and regulatory changes. Customise your reporting and get a direct view into your funds. Give members online access to their accounts.

Spend less time managing problems

We are proud of the high standard of our work. Our error and complaint rates are very low. If members need help, they speak directly with the hands-on administrators of their fund.

Scale up your contact centre without significant capital outlay

As an Australian Financial Services Licence (AFSL) holder we are licenced to handle members’ applications, redemptions and instructions. Grow your investor contact centre and stay on top of legislative changes without having to invest in new systems or equipment.
