Investing in Australian Shares and ETFs: A 2025 Guide

Australians are increasingly turning to direct share and ETF investing as an alternative to property and savings accounts. With the ASX delivering around 7% p.a. in long-run total returns and a uniquely generous franking credit system, Australian shares offer compelling after-tax returns.

Dollar Cost Averaging vs Lump Sum — What the Research Says

Research consistently shows that lump sum investing outperforms dollar cost averaging (DCA) approximately two-thirds of the time in rising markets — because more money is invested and compounding earlier. However, DCA reduces the psychological risk of investing at a market peak and suits most Australians who invest from regular income rather than a windfall.

The practical answer: invest your lump sum immediately if you have it, and DCA any ongoing contributions. Don't hold cash waiting for "the right time."

Franking Credits — Australia's Unique Tax Advantage

Australian companies pay 30% corporate tax before distributing dividends. The ATO allows shareholders to claim this tax as a credit (imputation). A $100 fully franked dividend comes with a $42.86 franking credit (30/70), meaning you received $142.86 in pre-tax income. For investors on marginal rates below 30%, the excess franking credit is refunded in cash after lodging a tax return.
