Direct answer
Australia’s inflation rose to 4.3% in the year to September 2026, up from 4.0% in August, according to the Australian Bureau of Statistics. The result was higher than the 4.2% economists had expected, and it has sharply raised expectations that the Reserve Bank of Australia will raise interest rates again at its meeting on November 3.
What happened
The Australian Bureau of Statistics released the September consumer price index on October 28, 2026. Prices rose 0.8% in the month alone, up from 0.4% in August, taking the annual rate to 4.3%.
Housing was the largest contributor to annual inflation in September, rising 5.2%, the statistics bureau said. Transport was the second largest contributor, rising 8.7%, driven by higher automotive fuel prices.
The Reserve Bank’s preferred underlying measure also moved higher. Trimmed mean inflation, which strips out the most volatile price moves, rose 3.6% over the year to September, up from a revised 3.5% in August. That measure matters because it gives a clearer read on lasting price pressure than the headline figure alone.
The Reserve Bank had already raised its cash rate by 25 basis points to 4.60% on September 29, 2026, its fourth hike of the year. After the September inflation release, money markets priced about an 85% chance of another quarter point hike on November 3, up from about 69% before the data. All four major Australian banks now expect a hike to 4.85%, which would take rates to their highest level in 18 years.
Reserve Bank Deputy Governor Andrew Hauser told a Senate hearing on the day of the release that inflation was broadly in line with the central bank’s expectations but was still too high. The bank targets inflation between 2% and 3%, so a 4.3% reading sits well above that range.
Why it matters for beginners
Inflation measures how fast the general level of prices rises. When inflation runs at 4.3%, a basket of goods and services that cost 100 dollars a year earlier now costs about 104.30 dollars. That squeezes household budgets, especially when wages do not keep pace.
Central banks raise interest rates to cool inflation. Higher rates make borrowing more expensive and saving more rewarding, which tends to slow spending and ease price pressure over time. The trade-off is that mortgages, business loans, and other borrowing also become more costly.
This is a useful reminder that inflation is not just an Australian story. Prices have been running hot in several countries this year, including in our recent post on Sri Lanka, where inflation hit 8.3% in October. When inflation stays above target in many places at once, central banks around the world often move in the same direction, and that can affect markets everywhere.
For beginners, the lesson is simple: watch inflation data, because it is one of the main inputs central banks use when they decide whether to raise, hold, or cut rates. Those rate decisions then flow through to mortgage costs, savings returns, and investment markets.
What to watch next
The Reserve Bank of Australia announces its next rate decision on November 3, 2026, after its meeting on November 2 and 3. Watch whether the bank raises the cash rate to 4.85% as markets now expect, and what Governor Michele Bullock says about the outlook for inflation.
Also watch the next inflation release, for October, due on November 25, 2026. If inflation cools from here, the case for further hikes weakens. If it stays high, markets may start pricing in even more tightening.

FAQ
What is Australia’s inflation rate right now? Australia’s consumer price index rose 4.3% in the year to September 2026, up from 4.0% in the year to August.
Why is a rate hike expected in November? Because inflation came in higher than expected and sits well above the Reserve Bank’s 2% to 3% target, markets and all four major banks now expect a quarter point hike on November 3, taking the cash rate from 4.60% to 4.85%.
What is trimmed mean inflation? Trimmed mean inflation removes the items with the largest price rises and falls, giving a steadier measure of underlying price pressure. In September it was 3.6% over the year, up from a revised 3.5% in August.
Does this affect people outside Australia? Directly, no, but it matters for global markets. When a major central bank is expected to raise rates, it can affect currency values, bond yields, and investor sentiment in other countries too.
