The 8 Money Myths This Quiz Busts (and Why They're So Sticky)
Money myths stick around because nobody teaches this stuff at school, plenty of people quietly benefit from the confusion, and social media loves a confident bad take. So here's the full cast, so you can see which ones you've been repeating (we've all done it). Each one links to the calculator that proves the point on your own numbers.
“Getting a pay rise can leave you worse off overall.”
MythTax brackets are marginal, so only the dollars above each threshold are taxed higher. A pay rise always lifts your take-home pay.

“HECS-HELP charges compounding interest, like a credit card.”
MythThere's no interest on HECS. The balance is indexed once a year, roughly with inflation or wage growth, whichever is lower.

“Renting is always throwing money away, buying is always better.”
MythBuying carries stamp duty, interest and maintenance; renting carries none of those but builds no equity. Which wins depends on your numbers.

“The 50% CGT discount applies after you've held an asset 12 months.”
TrueThis one's actually true for individuals. Hold an asset 12 months or more before selling and only half the gain is taxed.

“You need a lot of money to start investing.”
MythPlenty of platforms let you start small, some micro-investing options under $10. Consistency matters far more than the size of your first buy.

“Your emergency fund should be invested so it grows faster.”
MythIt has to be there in a downturn, which is exactly when markets fall. Keep it safe and accessible, not exposed to the share market.

“An unused credit card limit doesn't affect your borrowing power.”
MythLenders assess you as if every card is maxed out, even ones you clear each month. A high limit can quietly shrink what a bank will lend.

“The order you pay off multiple debts in doesn't matter.”
MythHighest-rate-first (avalanche) minimises interest; smallest-balance-first (snowball) keeps you motivated. The order changes what you pay.

Why Money Myths Cost Australians Real Money
These aren't obscure trivia. They're the beliefs that shape real decisions: whether you take the pay rise, how you rank your debts, how big a credit limit you carry into a home loan application. Repeat the wrong one at the wrong moment and it quietly costs you, sometimes thousands. Surveys of financial literacy in Australia keep finding the same gaps, especially around compound interest, tax and investment risk, and that isn't a knock on anyone. It's just what happens when the rules were never properly explained.
A money myth is dangerous precisely because it sounds sensible. The fix isn't being smarter, it's checking the confident-sounding rule against how things actually work in Australia.
The Myths That Trip Up the Most Australians
Three of these myths cause more damage than the rest, and all three come down to misreading how the Australian system works:
- Marginal tax brackets. A pay rise never lowers your take-home pay, because only the income above each threshold is taxed at the higher rate. See exactly how the tax brackets work.
- HECS-HELP indexation. It isn't interest, it's an annual CPI-linked adjustment, which behaves very differently to a credit card. Our HECS-HELP guide covers indexation in full.
- Debt payoff order. Paying highest-rate debt first minimises total interest, while smallest-balance-first keeps you motivated. Snowball vs avalanche breaks down which suits you.
A couple more worth un-learning: you don't need much to start investing, and the power of compounding means starting small early beats starting big later.

Frequently Asked Questions
Is it true you need a lot of money to start investing in Australia?
No. Most ETF platforms let you start with as little as $50 to $500, and some micro-investing options start under $10. The "investing is for the wealthy" myth is one of the most expensive beliefs you can hold, because compound growth doesn't care how small your first deposit is.
Is renting really throwing money away?
Not automatically. Rent buys you shelter, flexibility, and the ability to invest the difference. Whether buying beats renting depends on your market, your timeline, and what you do with the money you're not tipping into a deposit. The maths is more nuanced than the myth suggests.
Are credit cards always bad for your finances?
No. Used well, a credit card is free short-term credit, purchase protection and points. The problem is carrying a balance at 20% plus interest. The card isn't the villain, a revolving balance is. On the borrowing side, even a card you clear every month can shrink your home loan borrowing power, because lenders assess the whole limit.
What is the CGT 50% discount in Australia?
If you hold an asset like shares or property for more than 12 months before selling, only half the capital gain gets added to your taxable income. This is a real, ATO-confirmed concession, not a myth, and it's one of the most powerful legal tax breaks available to Australian investors.
Do I need to understand the stock market to invest?
Not really. Index funds and ETFs let you own hundreds of companies at once without picking individual stocks. Over the long run, passive index investing tends to beat active stock-picking anyway, so you can skip the ticker-watching.
Is all debt bad?
No. Debt used to buy an appreciating asset like property, education or a business, at a rate lower than the asset's growth, can build wealth. High-interest consumer debt like credit cards and buy-now-pay-later is the real problem, not debt itself.
Should I wait until I earn more before I start saving or investing?
Waiting is one of the most expensive money decisions people make. Time in the market beats timing the market. Starting with $25 a week at 25 usually beats starting with $200 a week at 35, because the early dollars have the most years to compound.
Is this quiz the same as financial advice?
No. It's a knowledge check on whether common statements about money are true under Australian rules, not a personalised assessment of your situation. A few answers also depend on your own circumstances. For advice that accounts for your specific situation, speak with a licensed financial adviser.
