Super Strategies — How to Maximise Your Superannuation in Australia

The decisions you make about your superannuation — which fund you use, how much you contribute, and which investment option you choose — can make a difference of hundreds of thousands of dollars to your retirement balance. This section covers the key strategic levers available within Australia’s super system.

The Five Highest-Impact Decisions

1. Reduce fees. The impact of fees on a super balance compounds over decades. A difference of 0.5% per year in fees on a $200,000 balance costs approximately $100,000 over 30 years (assuming 7% returns). APRA’s annual performance test and the Heatmap make it easier to compare your fund’s fees and net returns.

2. Check your investment option. Most Australians are defaulted into a balanced or MySuper option. For those 20–40 years from retirement, a growth or high-growth option has historically produced better long-term returns — though with more short-term volatility. This is typically the single highest-impact decision for younger members.

3. Consolidate multiple accounts. Holding multiple super accounts means paying multiple sets of fees and potentially multiple insurance premiums. The ATO’s myGov platform shows all your super accounts in one place. Consolidating into one fund eliminates duplicated costs.

4. Increase concessional contributions. The concessional contributions cap is $30,000 per year for FY2025–26. Many Australians only receive employer SG (12% of salary). For a $100,000 salary, that is $12,000 in super — leaving $18,000 of concessional cap unused. Salary sacrifice or personal deductible contributions up to the cap reduce taxable income and build super simultaneously.

5. Review insurance inside super. Super funds automatically provide life, total and permanent disability (TPD), and sometimes income protection insurance. Premiums are deducted from your super balance. Reviewing whether the coverage level is appropriate — and whether it’s worth holding inside or outside super — can prevent unnecessary erosion of your balance.

Salary Sacrifice vs Investing Outside Super

The core trade-off of putting extra money into super is tax efficiency versus liquidity. Concessional contributions are taxed at only 15% — significantly lower than most marginal rates — making super an extremely tax-effective vehicle. However, super is generally inaccessible until you reach preservation age (currently 60 for those born after 1964).

For someone with a 20+ year investment horizon and no immediate need for liquidity, salary sacrifice into super is often the more tax-efficient choice compared to investing in shares or property outside super. For someone who may need the capital within 10 years, the access restriction matters more.

Catch-Up Contributions

If your total super balance (TSB) is under $500,000 at 30 June of the previous financial year, you can carry forward unused concessional cap space from the past five years and make a catch-up contribution. This is valuable for those who had career breaks, reduced income years, or simply did not maximise contributions earlier.

Boosting Super Before Retirement

For those within 10 years of retirement, several additional strategies become available:

• Catch-up concessional contributions (TSB under $500,000)
• Downsizer contributions — if you are aged 55 or over and sell your principal residence you have owned for at least 10 years, you can contribute up to $300,000 each (or $600,000 for a couple) to super from the sale proceeds, outside the normal caps
• Transition to Retirement (TTR) income streams allow those who have reached preservation age to access super while continuing to work, which can be used as a tax-minimisation strategy

The Transfer Balance Cap

When you move your super from accumulation phase to pension phase (retirement), the Transfer Balance Cap (TBC) limits how much can be in a tax-free pension account. For FY2025–26 the general TBC is $2.0 million. Earnings on balances in a pension account up to the TBC are tax-free; amounts above it remain in accumulation phase, where earnings are taxed at 15%.

Frequently Asked Questions

What is the most effective way to increase my superannuation? The highest-impact actions are typically: switch to a lower-fee fund, choose a growth investment option if you have a long time horizon, consolidate multiple accounts, and salary sacrifice to the concessional cap. The right combination depends on your age, income, and circumstances.

Is it better to pay off a mortgage or put extra money in super? This depends on the mortgage interest rate and your marginal tax rate. At current mortgage rates (5.5–7.0%), the guaranteed tax-free return of paying off debt often competes favourably with voluntary super contributions, especially for those below the top marginal rate. Neither is universally better — both have merit.

What is the transfer balance cap in Australia? The Transfer Balance Cap is $2.0 million for FY2025–26. It limits the amount you can transfer from your super accumulation account into a tax-free retirement pension account.

Can I access my super at 60 in Australia? Yes. If you were born after 30 June 1964, your preservation age is 60. Once you turn 60 and retire (or meet another condition of release), you can access your super tax-free.
