### Australia's Inflation Jumps to 4.3 Per Cent

Prices in Australia are rising faster again. New figures from the Australian Bureau of Statistics (ABS), released on 28 October, show that consumer prices rose 4.3 per cent in the year to September 2026. That is up from 4 per cent in August and well above the Reserve Bank of Australia's target range of 2 to 3 per cent.

Housing was the biggest driver, with costs up 5.2 per cent over the year. Transport was the second-largest contributor, mainly because of fuel. Fuel prices alone jumped 9.4 per cent in the month of September as global oil prices climbed. Domestic holiday travel and accommodation also became more expensive.

Underlying inflation, measured by the "trimmed mean", came in at 3.6 per cent. This measure removes the biggest price swings, so economists watch it closely to understand the long-term trend.

The figures add pressure on the central bank, which will announce its next interest rate decision on 3 November. Financial markets now see a high chance of another rate rise. For households, including young people on working holiday visas, that could mean higher housing costs, pricier petrol and less money left at the end of each week.

The English article above is an original learning text written from [official ABS data](https://www.abs.gov.au/media-centre/media-releases/cpi-rose-43-year-september-2026) and [ABC News](https://www.abc.net.au/news/2026-10-28/inflation-september-cpi-ahead-of-november-interest-rate-call/107317382) reporting. It is not a word-for-word copy of any news report.

## The story in plain English

Prices in Australia are going up faster. New ABS numbers show prices were 4.3% higher in September 2026 than a year before. In August the number was 4%. The central bank wants it between 2% and 3%, so 4.3% is too high.

Housing pushed prices up the most: it cost 5.2% more than a year ago. Transport was next, mostly because of fuel. In September alone, fuel prices went up 9.4% because world oil prices rose. Holidays and hotels inside Australia also cost more.

Experts also look at "underlying" inflation, which leaves out the prices that change the most. This number was 3.6%, and it helps them see the long-term direction of prices.

The central bank will make its next interest rate decision on 3 November, and many people think it will raise rates again. For ordinary people, including young working holiday makers, this could mean higher rent, more expensive petrol and less money left each week.

| inflation | rising prices | A general rise in prices |
| inflation rate | how fast prices rise | The percentage prices rise by, e.g. 4.3 per cent |
