📊 Super Fund Cost vs Return
- The cheapest super options in Australia are clustered at the low-cost end, yet deliver solid long-term returns.
- Higher cost funds (like Vanguard) deliver competitive returns but with a minor fee penalty.
- The standout performer is the Hostplus International Shares Indexed option, which has had a absolute ripper few years helped by the US tech giants (the Magnificent Seven). This highlights why international exposure is key for your nest egg.
📊 Hostplus vs AustralianSuper: Geographic Exposure
- Hostplus International Shares – Indexed offers 100% international equity (0% home bias to Australia).
- Vanguard Super includes a ~10% allocation to emerging markets.
- Rest and AustralianSuper hold a stronger Australian equity component (~25%) than the pure international options.
🧩 Key Insights for Australian Super Investors
- Hostplus Indexed series remains the fee leader, with investment fees under ~0.09% to 0.12% p.a. plus the standard admin fee.
- AustralianSuper and Rest Indexed options are very close behind in cost and offer excellent global diversification.
- Vanguard Super growth fees sit around triple the cost (~0.38%), but add ~10% emerging markets exposure—a valid trade-off for broader index coverage.
- Emerging markets exposure: Only Vanguard openly incorporates a ~10% EM slice into its growth product; the other index options lean heavily on developed markets.
- All five options are passively managed index-based super funds, meaning they regularly rebalance and are perfect for a "set and forget" strategy.
