Managing Money in Your 30s in Australia — Financial Priorities

Your 30s are typically the decade of major financial commitments — buying a home, starting a family, building a career. Incomes usually grow significantly, but so do expenses. Strategic financial decisions in your 30s set the foundation for long-term wealth.

The Key Financial Priorities in Your 30s

1. Mortgage Management

For many Australians, the 30s bring a first (or second) home purchase. A mortgage is likely the largest financial commitment you will take on.

Key actions:

• Compare mortgage rates regularly — loyalty rarely pays with banks; refinancing to a lower rate can save thousands per year
• Consider an offset account — linking savings to an offset account reduces the interest charged on your mortgage
• Make extra repayments — even an extra $200/month can save years off a 30-year mortgage and tens of thousands in interest
• Review your mortgage every 2–3 years — rates change and you may qualify for better products as your equity grows

2. Insurance and Protection

In your 30s — especially with a partner, children, or a mortgage — income protection, life insurance, and TPD (total and permanent disability) insurance become important.

Many Australians have life insurance and TPD inside super — check your super fund’s insurance cover. It is often automatic but may be inadequate.

Key considerations:

• Life insurance: covers your family if you die — essential if you have dependants and/or a mortgage
• Income protection: covers up to 70% of income if you cannot work due to illness or injury — often the most important cover for working Australians
• TPD: lump sum if you cannot work again in your occupation

Review whether default super cover meets your needs or whether additional cover is required.

3. Salary Sacrifice and Super Strategy

By your 30s, any super lost to default fund fees in your 20s is worth recovering. Review:

• Consolidate remaining accounts (if not done in your 20s)
• Investment option — at 35, you have 25+ years until preservation age; growth options remain appropriate for most people
• Salary sacrifice — concessional contribution limit is $30,000/year (FY2025–26), including employer SGC. If you have capacity, salary sacrificing into super reduces taxable income and builds retirement wealth tax-efficiently

4. Children and Family Costs

Having children significantly increases expenses. Key financial considerations:

• Child Care Subsidy (CCS) — check eligibility; reduces child care costs based on income and activity test
• Family Tax Benefit — check eligibility for Part A and Part B
• Review your budget — parental leave may reduce household income for a period; plan ahead
• HECS debt and partner’s income — Family Tax Benefit calculations use combined family income

5. Continue Building Your Investment Portfolio

Income typically grows in the 30s — resist the temptation to increase lifestyle spending proportionally. Redirect income growth into investments:

• Regular ETF contributions (dollar-cost averaging)
• Ensure investing continues through market downturns — this is when the discipline of your 20s either holds or breaks

Wealth Building in Your 30s

The median household net worth for 35–44 year olds in Australia is approximately $237,000 (ABS data). The mean is much higher (~$437,000) due to property owners and high earners lifting the average.

Key drivers of net worth growth in your 30s:

• Home equity accumulation (mortgage principal repayment + capital growth)
• Super growth (11.5% contributions + compounding)
• Investment portfolio growth
• Debt reduction (HECS, car loans, personal loans)

Common Mistakes in Your 30s

FAQ

How much super should I have at 35? A commonly cited benchmark: approximately 1× your annual salary in super by age 35. On $100,000 income, that would be ~$100,000. The ATO’s online super projection tool provides personalised estimates. The actual amount matters less than being on track with contributions.

Should I prioritise extra mortgage repayments or investing in my 30s? Both strategies have merit. Extra mortgage repayments give a guaranteed return equal to your mortgage rate. Investing offers potentially higher long-term returns but with more variability. Many Australians do both — extra repayments plus regular investment contributions. See the Pay Off Debt or Invest guide.

How do I balance saving for kids’ education with other goals? Education bonds and investment accounts can be used for education savings. However, most financial planners suggest funding your own retirement before children’s education — students have access to HECS-HELP, while there is no equivalent government loan for retirement.
