Most people choose a super fund and never look at the investment option inside it. That second choice, the mix of shares, property, bonds and cash your balance is invested in, shapes your retirement more than the logo on the statement. Over a 30 year career, the difference between a growth option and a conservative one can run to hundreds of thousands of dollars.
The reason is compounding. A percentage point of extra return each year looks trivial on one statement and enormous across a working life. A 30 year old on a growth option that returns one per cent a year more than a balanced one can retire with well over $100,000 more, from the same contributions. The trade-off is that growth options fall harder in bad years, and that trade-off is the whole discussion.
What “growth” means inside super
Super funds sort investments into defensive and growth assets, then blend them into pre-mixed options.
| Option | Typical growth assets | Behaviour |
|---|---|---|
| High growth | 85–100% | Highest expected return, largest swings |
| Growth | 70–85% | Strong long-run return, real short-term falls |
| Balanced | 60–70% | The common default, a middle path |
| Conservative | 20–40% | Steadier, lower expected return |
| Cash | 0% | Stable, but often loses to inflation over time |
Growth assets are shares and property. They carry the return and the volatility. Defensive assets are bonds and cash, which cushion falls but drag on long-run growth. The pre-mixed option you sit in sets your balance of the two, usually without you choosing it directly.
The default is not always the right fit. Most funds place new members in a balanced or “MySuper” option. For a younger member with decades until retirement, that can be more conservative than their time horizon warrants. Time is the single biggest reason a growth tilt tends to suit people early in their careers: a market fall at 35 has 30 years to recover, so the extra long-run return usually outweighs the larger dips along the way.
Why the mix should change as you age
The case for growth rests on having time to ride out falls. As that time shortens, the maths shifts.
The danger near retirement is sequencing risk. A sharp market fall in the few years either side of the day you stop working lands at the worst possible moment, because you start drawing an income from a shrunken balance and lock in the loss instead of waiting for the recovery. The same fall at 40 is a buying opportunity. At 64 it can reshape your retirement.
This is why a sensible glide path reduces growth exposure as retirement nears, without abandoning growth entirely. People are retiring earlier and living longer, so a 67 year old may need their money to last 30 years. Going fully conservative on day one trades one risk for another: inflation slowly eroding a balance that has to stretch across three decades. A retiree usually still needs meaningful growth exposure, just less than they held at 40, and held alongside a cash buffer that funds the next few years of income so they never have to sell growth assets in a downturn.
Before retirement: build the balance
In the accumulation years, three levers do the heavy lifting.
- Contribute more, earlier. Concessional contributions up to the annual cap are taxed at 15 per cent rather than your marginal rate, and every extra dollar compounds for longer the sooner it goes in.
- Match the option to your horizon. Someone 20 years from retirement is investing for a date two decades away, not for this year’s return. A growth tilt fits that horizon for most people.
- Stop reacting to headlines. The most expensive super decision is switching to cash after a market fall, which converts a paper loss into a real one and misses the recovery. Funds that stayed invested through past downturns recovered; those that sold did not.
During retirement: protect and draw
Once you are drawing an income, the goal changes from growing the balance to making it last.
A common structure, sometimes called a bucket approach, splits the balance by time. A cash bucket holds the next two to three years of income so day-to-day spending never depends on selling shares in a bad month. The rest stays in growth and balanced assets to keep working across a long retirement. It is a simple idea that directly answers sequencing risk.
For SMSF trustees, the same principles apply with more control and more responsibility. You choose the assets directly, which allows a precise growth tilt and a deliberate cash buffer, but the investment strategy, its documentation and the fund’s ongoing administration sit with you and your adviser.
The risk that remains
None of this removes risk. Growth options will fall, sometimes sharply, and past returns do not promise future ones. The right mix depends on your age, your other assets, your income needs and how you actually cope when a balance drops. That last point is personal, and it is why a mix that looks correct on paper can be wrong for the person holding it.
