Retirement planning often centres on one deceptively simple question:
How much superannuation is enough?
The usual approach is to find a benchmark, compare it with your balance, and decide whether you are on track.
But "enough" can be a dangerous target.
A retirement portfolio may need to withstand market downturns, rising living costs, unexpected expenses, and several decades without employment income. A published benchmark can provide a useful starting point, but it may leave little room when life refuses to follow the spreadsheet.
For Australians approaching retirement, avoiding a few common investment errors could make a meaningful difference to the size and durability of their superannuation portfolio.

The average balance is not the finish line
According to figures cited by the Association of Superannuation Funds of Australia, the average superannuation balance for Australians aged 55 to 59 is approximately $319,743 for men and $242,945 for women.
Those are substantial sums. However, an average is not necessarily an adequate retirement target.
ASFA estimates that a comfortable retirement currently requires annual spending of roughly $54,840 for a single homeowner and $77,375 for a couple. Its suggested starting balances are approximately $630,000 for singles and $730,000 for couples, assuming home ownership and some Age Pension support.
That suggests many Australians in their late 50s may still have a meaningful gap to close.
More importantly, even the published benchmark should not automatically be treated as the finish line.
These estimates depend on assumptions about spending, investment returns, lifespan, housing, and government support. Someone who wants to retire early, travel regularly, support adult children, carry debt into retirement, or simply maintain greater financial flexibility may need considerably more.
A larger superannuation portfolio is not only about funding a more expensive lifestyle. It can create a buffer when markets disappoint, costs rise faster than expected, or personal circumstances change.
Going defensive too early can be costly
It is understandable that investors become more protective of their superannuation as retirement approaches.
After spending decades building a portfolio, few people want to see a meaningful portion of it disappear during a market downturn.
But removing too much growth exposure can create a different risk: the portfolio may stop growing fast enough.
An Australian aged 55 might still have another decade before retirement and potentially 25 to 35 years of life after leaving work. That remains a long investment horizon.
Cash and defensive assets can play an important role in managing short-term spending needs and market volatility. However, a portfolio concentrated too heavily in low-return investments may struggle to keep pace with inflation over several decades.
The objective is not to take reckless risks close to retirement. It is to avoid assuming that retirement marks the end of the need for growth.
The larger the portfolio becomes, the more powerful investment returns can also become in dollar terms. A 7% return on $100,000 adds $7,000 before fees and taxes. The same return on $600,000 adds $42,000.
That is why the years immediately before retirement can remain an important period for compounding rather than simply capital preservation.
Chasing income can weaken long-term growth
Many investors naturally begin thinking about dividends as retirement approaches.
Reliable income can be valuable. However, concentrating on the highest-yielding investments too early may hold back portfolio growth or expose investors to risks that are not immediately obvious.
A large dividend yield can sometimes signal that a company's share price has fallen, its earnings are under pressure, or the market expects its payout to be reduced.
There is also a broader strategic concern.
An investor who prioritises income throughout the accumulation phase may favour mature, slower-growing businesses while overlooking companies or diversified funds with stronger long-term growth potential.
Before retirement, the main objective may still be to build the largest high-quality portfolio possible. Income can become a greater focus when the portfolio is required to fund regular withdrawals.
Dividends matter, but so do capital growth, diversification, business quality, fees, and the sustainability of returns. Retirement wealth is ultimately shaped by total returns, not income alone.
Foolish takeaway
For many Australians, the biggest threat to retirement plans may not be one dramatic market crash.
It may be a series of quieter mistakes: treating the average as the target, becoming defensive too soon, or chasing income before the portfolio is large enough.
The encouraging part is that the years from 55 to 65 can still offer considerable opportunity.
Continued employer contributions, additional personal contributions, sensible asset allocation, and long-term compounding may all help strengthen the final retirement outcome.
A bigger superannuation portfolio cannot eliminate every risk. However, it can create more choices, greater resilience, and more room for life to unfold differently from the plan.
