It has been nearly five years since inflation arrived in Australia, and the cumulative damage is now legible in the numbers. The consumer price index has climbed 23% since late 2021 — but the story is not a single number. It is the widening gap between essentials that households cannot avoid and discretionary goods they can. The essentials squeeze is severe. Insurance premiums are up 46%. Gas has surged 49%. Electricity bills have risen 35%, a zigzagging line that reflects government subsidies turning on and off without changing the underlying trend. Rents are up 27%. Home building costs are 36% higher. Postal services have risen 40%. These are not optional line items. Supermarket staples tell their own story. Cooking oil and eggs have jumped more than 40%. Bread, milk, and fruit are all up over 30% in five years. Chicken and vegetables, notably, have stayed below headline inflation — a rare reprieve in the grocery aisle. The latest annual figure — 4.3% CPI in the year to September 2026 — is being driven substantially by the second global energy shock. The US-Israel war with Iran, beginning February 2026, pushed fuel costs up more than 20% in a single year, though over the longer term fuel has roughly tracked overall CPI. That 'merely matching inflation' framing obscures how much inflation itself has compounded. The good news, such as it is, lives in the non-essential categories. Glassware and household utensils are actually cheaper than in late 2021. Small electrical appliances cost the same. Women's clothing is up just 7%, men's only 4%. Public transport fares have fallen 5%, thanks to state and territory government decisions. Childcare, despite recent increases, is up only 7% — a result that would surprise most parents. Government intervention has been selective and temporary. Electricity subsidies provided short-term relief but left the structural upward trend untouched. Public transport fee reductions and childcare subsidy expansions are genuine wins, but they sit alongside categories where governments have no lever — insurance, construction costs, and food staples are set by global commodity markets, concentrated industry structures, and supply constraints. The pattern that emerges after five years is structural: the things Australians must buy are inflating fastest, while the things they can defer or skip are stable or falling. This is a quiet transfer of purchasing power away from lower-income households, who spend the highest share of income on essentials, toward asset owners and the firms that price insurance, energy, and housing.
