Australian CPI peaked at 7.8% in December 2022 — a 30-year high — driven by energy prices, supply chain disruption, and housing costs. The RBA's aggressive rate hiking cycle brought inflation down, but the price level remains elevated and the cost of living is a continued political flashpoint.

What's still elevated in Australia

  • Groceries — Coles and Woolworths prices remain well above 2020 levels
  • Insurance premiums — rising 10-20%+ annually in many categories
  • Electricity — network charges and retail margins keeping bills elevated

💡 Franking credits: an Australian inflation-fighting tool Australian equities pay dividends with franking credits attached — a tax credit for company tax already paid. For investors in lower tax brackets, franking credits can result in tax refunds, effectively boosting the after-tax yield of Australian shares. This is unique to Australia and not available in most other markets.
