Deciding how to allocate assets in a retirement portfolio is one of the most consequential financial decisions Australian retirees face. Too conservative and inflation erodes your purchasing power over a 25-year retirement. Too aggressive and an early market crash can permanently impair your portfolio. The right allocation balances your income needs, risk tolerance, investment time horizon, and the role of the Age Pension in your overall income plan.
The Framework: Growth vs Defensive
Retirement portfolio allocation is typically expressed as a split between:
- Growth assets: Australian and international shares, listed property/REITs, infrastructure — higher expected return, higher short-term volatility
- Defensive assets: Cash, term deposits, Australian and international bonds — lower expected return, lower short-term volatility
Standard Allocation Guidelines for Australian Retirees
| Profile | Growth assets | Defensive assets | Typical scenario |
|---|---|---|---|
| Conservative | 0–30% | 70–100% | Age 80+, very low risk tolerance, large guaranteed income (annuity/pension) |
| Moderately conservative | 30–50% | 50–70% | Age 75–80, modest income needs, partial Age Pension |
| Balanced | 50–60% | 40–50% | Age 67–75, standard retirement, some Age Pension |
| Growth | 60–75% | 25–40% | Age 60–67, long horizon, no Age Pension yet |
| High growth | 75%+ | <25% | Pre-retirement accumulation, age <55 |
These are general frameworks — appropriate allocations depend on individual circumstances.
Why Retirees Still Need Growth Assets
Historically, Australian shares have delivered inflation-adjusted returns of approximately 4–7% per year over the long term. Cash and term deposits rarely beat inflation over 10+ year periods.
A retiree retiring at 67 has an expected investment horizon of 20–25+ years. Over this period:
- A conservative (100% defensive) portfolio may fail to maintain purchasing power
- Inflation at 3% per year erodes purchasing power by 45% over 20 years
- Growth assets provide the engine to counteract inflation over the long term
The Bucket Approach to Allocation
Rather than a single blended portfolio, many Australian retirees use a bucket approach:
| Bucket | Assets | Purpose | Horizon |
|---|---|---|---|
| 1 (Cash) | Cash, term deposits | 1–2 years of living expenses | 0–2 years |
| 2 (Income) | Bonds, hybrid securities, conservative balanced | Medium-term spending reserve | 2–7 years |
| 3 (Growth) | Australian and international shares | Long-term growth and inflation protection | 7+ years |
The cash bucket means you never have to sell growth assets in a down market — reducing sequence of returns risk.

Australian Super Fund Options in Pension Phase
Most super funds offer standardised investment options. In pension phase:
| Option | Typical growth/defensive split | Use case |
|---|---|---|
| Cash | 0% growth / 100% defensive | Short-term capital only |
| Conservative | ~25% / ~75% | Low risk tolerance, age 80+ |
| Balanced | ~55% / ~45% | Standard retirement allocation |
| Growth | ~70% / ~30% | Long horizon, younger retiree |
| High growth | ~85% / ~15% | Very long horizon, high risk tolerance |
In pension phase, you can generally split across multiple investment options — for example, 2 years of spending in a cash option plus the remainder in a balanced or growth option.
Rebalancing in Retirement
Market movements will cause your actual allocation to drift from your target. Rebalancing — selling outperforming assets to buy underperforming ones — keeps the portfolio aligned with your risk tolerance.
In retirement, rebalancing can be done by:
- Directing withdrawals from the outperforming asset class (selling shares when they have risen)
- Directing any new contributions (e.g., re-investing dividends) into the underperforming asset class
Avoid frequent rebalancing (transaction costs, tax implications); annually or when allocation drifts by more than 5–10% is typically sufficient.

Frequently Asked Questions
What is the best asset allocation for a 70-year-old Australian retiree? A balanced to moderately conservative allocation is common for a 70-year-old — typically 40–55% growth assets and 45–60% defensive assets. However, the right allocation depends on your health, spending needs, other income sources (Age Pension, rental income), and risk tolerance. A financial adviser can help tailor this.
Should I have a separate investment option for my short-term spending needs? Yes — this is the core of the bucket strategy. Keeping 1–2 years of spending in cash or a cash-oriented option protects you from having to sell growth assets during market downturns. Many super funds allow you to hold multiple investment options simultaneously.
How often should I review my retirement portfolio allocation? At minimum annually, and after any major market movement (20%+ shift in equity values), life event (health change, death of a partner), or change in government pension rules. A financial adviser can help with this review.
