Australian export commodity prices started rising again in November.
The Reserve Bank of Australia's index of commodity prices was 0.1% higher in the month, in Special Drawing Rights terms, after falling by 0.4% in October.
The price index is measured in terms of special drawing rights, an average of four major currencies - the US dollar, euro, Japanese yen and the pound.
The RBA said prices for gold, coking coal and wheat fell.
AAP reports these were offset by increases in the prices of iron ore and thermal coal.
Over the 12 months to November, the index declined by 1.9%.
