Higher dairy prices pushed ANZ's commodity price index up 1.8 per cent last month.
But outside dairy products, which make up 47 per cent of the index, prices were soft especially in the meat and fibre sector, said ANZ economist Con Williams.
Whole milk powder had led the charge among dairy products, as dry conditions and the low milk price curtailing end-of-season milk supply had turned market sentiment around.
But prices for other commodities fell for the third month in a row, he said. Only venison managed a slight improvement and that was off a low base.
"Beef prices fell in the United States, given high Australian and New Zealand supply, port disruptions, weaker demand due to the recent cold snap and increasing poultry and pork supply. The port disruptions have been resolved, but importers have very high stocks at present, which will take some time to clear."
