Compare what each fund offers, then choose investment options to put their published costs and returns side by side.
Retail fund
MLC's MasterKey range includes employer, personal and Super & Pension Fundamentals accounts. The investment and insurance terms depend on which product you hold.
MasterKey Super Fundamentals is designed for individual members. Business Super is arranged through employers, and employer discounts or insurance subsidies can affect the comparison.
Retail investment platform
Rhythm Super is an IOOF-operated platform administered by HUB24, with an adviser-selected investment menu.
The service is offered through advisers. Confirm the current product requirements with the adviser and super PDS.
Choose the actual investment pathway for each account. For lifecycle products, select the named stage relevant to you. No stage is selected automatically.
The costs and returns belong to the selected product, option or lifecycle stage.
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.

| Membership and access | MasterKey Super Fundamentals is designed for individual members. Business Super is arranged through employers, and employer discounts or insurance subsidies can affect the comparison. Sources24 | The service is offered through advisers. Confirm the current product requirements with the adviser and super PDS. Sources12 |
| Accounts and products | MLC MasterKey products in MLC Super Fund. Expand, Plum and NAB-specific plans are separate product propositions. MLC MasterKey Business Super MLC MasterKey Personal Super MLC MasterKey Super and Pension Fundamentals MLC MySuper Sources17 | Rhythm Super and Pension. Sources12 |
| Investment choices | MLC MySuper for eligible MasterKey Business and Personal Super members; check the selected investment in Fundamentals. MasterKey Super Fundamentals offers ready-made choices, lower-cost and socially responsible portfolios, plus asset-class options for a member-built portfolio. MLC MySuper invests across mainstream asset classes with some private and alternative assets and uses active and passive managers. Sources23 | The menu includes managed funds, shares, ETFs, term deposits and separately managed accounts. Approved advisers can use the IOOF Managed Portfolio Service. Sources12 |
| Insurance | The insurance offer differs between Business, Personal and Fundamentals accounts. Business and Personal Super can include both an insurer premium and an insurance administration fee; Fundamentals insurance charges consist of the insurer premium. Check the applicable guide rather than assuming all MLC insurance is priced the same way. Sources47 | Check the current Rhythm Super PDS and any policy proposal for insurance access; HUB24-branded account terms are not automatically Rhythm terms. Sources12 |
| Retirement income | MasterKey Pension Fundamentals provides account-based and transition-to-retirement pension pathways. A member can assess the pension menu as part of planning a move into retirement, but the pension fee schedule must be checked separately. Sources67 | A pension product is available alongside super. Sources12 |
| Advice and support | Members can use MLC without a financial adviser. If they engage an adviser, fees for super-related advice may be deducted with consent and subject to product rules. Advice fees should be included in the overall cost of an advised arrangement. Sources4 | Advisers use the platform's transaction, portfolio and reporting tools to manage the member's account. Sources12 |
| Fee details to check | An employer may have negotiated reduced fees, shown in the plan's Features At A Glance document. Changes from 1 April 2026 removed the insurance-fee cap for affected Business and Personal Super members and reduced the cap on the percentage administration fee. These are distinct changes: lower administration fees do not necessarily mean a lower total cost for an insured member. Sources45 | Obtain a complete estimate including account administration, underlying investments, trading, cash and advice. The technology provider's fee schedule is not necessarily the Rhythm schedule. Sources12 |
| Comparing investment performance | Compare the exact MySuper portfolio or chosen MasterKey investment. Age and product matter, and a return from one underlying fund is not the return from an entire member account after every administration, insurance and advice charge. Show the MasterKey product name and employer discount assumptions. Separate insurance premium, insurance administration charge and adviser fee where relevant. Sources1234567 | Use the selected investments and actual account costs. A return from another IOOF or HUB24 product does not represent Rhythm. Sources12 |
THE SUPERGURU VIEW
MLC deserves an account-level review rather than a verdict based on the brand. The breadth of investments can help someone with a deliberate portfolio, while a workplace subsidy may change the price materially. For current members, the 2026 insurance-fee-cap change is a practical reason to check the statement.

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.
