Top super funds - this is how yours stacks up Were you a member of one of the 20 best superannuation funds of the past decade? SEE THE LIST Money by Anthony Keane Premium Content Subscriber only Australia's strongest superannuation funds of the past decade are delivering tens of thousands of extra dollars to their members, highlighting the importance of taking super seriously. Financial regulator APRA's latest fund-level data shows the best performers have produced a 10-year rate of return above 8 per cent, while the weakest returned barely half that amount. For an average 40-year-old worker with $50,000 in super, this can lead to a final retirement balance almost $200,000 lower - $246,000 instead of $439,000 - simply by being in the wrong fund.
