The Reserve Bank of Australia explains that inflation measures how fast prices are rising, while the Australian Bureau of Statistics calculates the Consumer Price Index independently. For the current data rather than an old headline, use the RBA inflation overview and the latest ABS CPI release.

What is inflation in Australia?
Inflation means the overall prices of the goods and services households buy are rising over time. It does not mean every price rises by the same amount, or that every household feels it in the same way.
Inflation, CPI and the cost of living
Inflation measures the pace of price rises
It is about how quickly prices are increasing across the economy, not simply whether one bill became more expensive this month.
CPI is the best-known measure
The Consumer Price Index tracks changes in the prices of a representative basket of goods and services that households typically buy.
Your personal costs can move differently
Households spend differently. A change in rent, fuel, food, insurance or childcare can matter more to one household than another, even when the headline CPI rate is the same.
Inflation appears in many news stories
It helps explain discussions about interest rates, wages, government budgets and household spending, which is why it is often reported alongside RBA decisions.
How Australia measures inflation
How to read an inflation headline
Check the period
Look for the month, quarter or year being compared. A figure without its timeframe is easy to misunderstand.
Ask what moved
A CPI release usually explains which categories had the largest effect. That is more useful than treating every price as moving equally.
Keep news context separate from personal decisions
Inflation data helps explain the economy, but it is not personal financial advice. Use official sources or a qualified adviser for decisions about your own finances.

What is CPI in Australia?
CPI means Consumer Price Index. The ABS uses it to measure changes in the prices of a representative basket of goods and services bought by households.

Not exactly. CPI is a broad measure of price changes, while cost-of-living pressure can feel different for each household depending on what it buys and pays for.
