Compare what each fund offers, then choose investment options to put their published costs and returns side by side.

By SuperGuru Group · Research checked 11 September 2026 · Historical APRA figures to 30 June 2026

CSS

Closed public sector scheme

CSS is a closed Commonwealth scheme whose benefit depends on more than the investment return shown on a statement.

Membership

Relevant to existing contributors, deferred members and pensioners. Some returning employees must or may resume contributing.

Retirement Benefits Fund

Closed public sector scheme

RBF retains defined benefit and pension arrangements for eligible Tasmanian public sector members.

Membership

Existing members, preserved members and eligible pensioners should check their particular membership category.

Source: APRA Comprehensive Product Performance Package 2026, published 28 August 2026. Fees reflect the reporting year to 30 June 2026, are net of tax, use standard arrangements and exclude member-activity fees. Dollar figures are rounded. They are not a current quote. Check the latest PDS for changes, insurance premiums and any separately charged advice.

Returns are annualised historical results. Different return bases, risk levels and periods cannot be treated as interchangeable. MySuper net returns use a $50,000 representative balance even when you change the fee balance. A lifecycle stage return does not track a person moving between stages. Missing figures mean not reported, not zero. Past returns do not predict future returns. Read our method and APRA's definitions.

THE SUPERGURU VIEW

Our take on CSS

Editorial assessment

For a CSS member, an ordinary fund ranking answers too little. Get a benefit estimate for the actual exit date and compare the pension and lump-sum choices before considering any transfer.

Who this profile is for

  • Existing CSS members reviewing retirement or a return to eligible employment.

What deserves a closer look

  • The scheme is closed to ordinary new membership.
  • A higher investment return elsewhere does not by itself show a better outcome than a CSS pension.

THE SUPERGURU VIEW

Our take on Retirement Benefits Fund

Editorial assessment

A remaining right to an RBF pension can be the most important part of an account. Ask for written confirmation of what would survive a withdrawal or transfer before comparing the balance with another fund.

Who this profile is for

  • Existing Tasmanian RBF members weighing preservation, a lump sum or an eligible pension.

What deserves a closer look

  • This is not a fund open to the general public.
  • Historical pension terms should not be assumed to apply to every member.

Before choosing between CSS and Retirement Benefits Fund

Use the membership rules to establish which accounts are available to you. Then compare the total price of the investment option and cover you need. A lower fee or higher historical return alone does not tell you which fund is suitable.

Ask both funds to confirm insurance acceptance, exclusions, waiting periods and whether cover would change when you leave your employer. Obtain advice before giving up a defined benefit or an insurance policy you may not be able to replace. ASIC Moneysmart explains the comparison checks.
