The annual rate of inflation is staying below the Reserve Bank's two to three per cent target, weighed down by falls in fuel prices.
Consumer prices were up 0.3 per cent in September, following a 0.1 rise in August, according to the TD Securities/Melbourne Institute monthly inflation gauge.
That's keeping the annual rate of inflation at 1.9 per cent to September, the highest since November 2014, but still below two per cent all year.
Price rises for tobacco, and holiday travel and accommodation, were offset by falls in the price of fuel, newspapers, books and stationery, and clothing.
TD head of Asia Pacific research Annette Beacher said she expects inflation to pick up in the September quarter, but stay within the RBA's target range.
"The weaker Australian dollar may be boosting imported prices, but benign domestic inflation provides an offset," she said.
TD Securities is not expecting the RBA to cut the cash rate in the foreseeable future after the central bank made two reductions earlier in this year.
"We expect tomorrow's RBA board meeting to be a placeholder, noting the lower exchange rate, China slowdown and that the US Federal Reserve is set to lift the cash rate in due course," Ms Beacher said.
