What is CPI?

  • CPI stands for Consumer Price Index.

  • It tracks changes in the average price of a basket of essential goods and services.

  • Common categories include food, housing, fuel, health, and education.

  • It’s used to measure inflation and overall cost of living trends.

CPI Annual Trend (2016–2025)

  • Annual CPI dropped sharply in 2020 due to COVID.

  • Peaked at 7.8% in 2022, highest in decades.

  • Now easing back to ~3.6% in 2024–2025.

  • Still above RBA’s target range of 2–3%.

The Grocery Basket Squeeze

  • Not all grocery items experienced the same inflation.
  • Bread & cereal products peaked at 7.2% in Jun 2024.
  • Fruit & vegetables surged to 8.5% in Sep 2024.
  • Staples like dairy and non-alcoholic beverages remained elevated.
  • Highlights the uneven pressure on household budgets.

Where Rent Hit Hardest

  • Perth tops the chart with an 8.9% rent increase.

  • Brisbane, Adelaide, and Melbourne saw notable hikes (5.5–5.8%).

  • Hobart was the only city with a decline (-1.3%).

  • Regional variation reflects uneven housing cost pressures across Australia.

The Rising Cost of Education

  • Education fees have increased significantly post COVID.

  • Secondary education jumped by +6.4% in March 2025.

  • Tertiary spikes in 2023 (+9.7%) reflect fee indexation changes.

  • Education CPI is only published in March, but shows consistent annual pressure.

Cost-of-Living Pressures: Are We Really Better Off?

  • Headline CPI dropped sharply from 7.0% in 2023 to 3.4% in 2025.
  • But essential categories didn’t ease as much:
    • Rent rose further from 4.9% → 5.5%
    • Education slightly declined from 5.9% → 5.2%
    • Groceries dropped from 4.1% → 3.7%
  • These are all above the headline CPI, showing core pressures remain.
  • Essentials are not improving as fast as the national average.

What the Data Tells Us About the Cost of Living

  • The overall CPI trend is declining, but not all categories are easing equally.

  • Rent and education costs continue to rise, disproportionately affecting lower-income households.

  • Grocery prices remain volatile, making budgeting difficult for many.

  • The data shows that while inflation is stabilising, the lived reality for essentials is still tough.

  • Policymakers and support systems need to consider category-specific pressure, not just overall CPI trends.

  • Future work could explore income-level impacts or regional differences to better inform targeted support policies.
