Prices charged by Australian producers for finished goods and services rose 1.1% in the September quarter and 3.6% from a year earlier, as higher rents, construction wages and copper costs outweighed a drop in fuel, according to data from the Australian Bureau of Statistics released Oct. 30.

The annual pace matched the June quarter, when the index jumped 1.3% on a spike in oil prices. This time, oil worked the other way: petroleum and coal product manufacturing prices in the final demand index fell 9.8% in the quarter. That producer inflation held at 3.6% anyway tells investors that the cost pressure in Australia is now coming mostly from domestic sources, which are harder for the central bank to wait out.

The Reserve Bank of Australia drew a similar conclusion on Tuesday. Its board raised the cash rate target by 25 basis points to 4.85%, saying in its statement that liaison with businesses shows many firms face cost pressures and are raising prices or planning to. The vote was 6-3, with three members preferring to hold at 4.60%. For investors in Asia, the move adds to a rate gap that has kept the Australian dollar near 70 U.S. cents.

Rents, Wages and Copper Drive Australia's Producer Prices

The ABS said the largest contributors to the quarterly rise in final demand were property operators, up 1.0% on strong demand and higher residential rents, and residential building construction, up 1.1%. The statistics bureau tied the construction increase to a shortage of skilled trades, which is pushing up wages, and to freight and transport charges on imported materials that remain high after the oil shock in the previous quarter.

Services added to the pressure. The Fair Work Commission's 4.75% increase in minimum award wages, the largest since 2023 according to the ABS, flowed into prices across several service industries from July 1, along with enterprise bargaining rises and annual contract reviews. Medical services prices rose 2.3% in the quarter after annual indexation of Medicare fees, and childcare rose 1.2%.

Fuel excise is outside the scope of producer price indexes, so the federal government's unwinding of fuel excise relief in July and August did not lift these figures directly, the ABS said. That contrasts with the consumer price index, which includes the tax and showed headline inflation of 4.3% in the year to September, as the September quarter CPI release reported.

Data Centres and the Middle East Conflict Lift Building Costs

Building construction prices rose 1.3% in the quarter and 4.9% over the year. Non-residential construction led with a 1.7% quarterly gain, followed by other residential building at 1.3% and houses at 1.0%. The ABS said demand from data centre construction and a large pipeline of infrastructure projects are adding to wage pressure on construction sites.

Materials costs tell a similar story. Input prices for house construction rose 1.0% in the quarter and 3.9% from a year earlier. Copper pipes and fittings jumped 9.5% and electrical cable and conduit rose 3.6%, which the bureau linked to global copper prices as demand from data centres and electrical goods outpaces supply. Electrical equipment costs for house builders are up 14.5% over 12 months. Plastic pipework and fittings rose 9.0% on higher global PVC costs that the ABS attributed to the Middle East conflict.

Brisbane recorded the largest quarterly rise in house construction input costs among capital cities at 1.6%, while Perth had the smallest at 0.4%. The Northern Territory posted a 4.6% rise in house construction output prices, its largest since the September quarter of 2021.

There was some relief for manufacturers. Input prices to manufacturing fell 1.0% in the quarter as crude oil came off its June quarter peak, and manufacturing output prices fell 1.3%. House construction output prices also slowed to 1.0% from 2.0% in the June quarter, which the ABS said reflected weaker demand from home buyers.

What the Producer Price Data Means for the RBA

The central bank's new forecasts, summarized in its Nov. 3 statement, show inflation staying above 3% for the coming year and not reaching the top of its 2% to 3% target band until late 2027, about three quarters later than it projected in August. The board said there are signs that higher fuel prices are passing through to other goods and services, and that AI-related investment is driving rapid price growth for technology-related goods.

The bank also noted that the economy is slowing, home prices have fallen significantly and unemployment has risen. Consumer spending had already stalled before the latest increase: household spending was flat in August from July, though 6.8% higher than a year earlier, according to the ABS household spending indicator.

The November move was the fifth rate increase this year, according to Australian Broker, which reported in September that the big four banks passed the previous increase on to variable home loan rates in full.

The next test comes on Nov. 4, when the ABS publishes its household spending indicator for September. The next producer price figures, for the December quarter, are due Jan. 29, 2027, and will include the bureau's planned reweighting of the construction index.
