China remained the country's top export destination in January, with exports up 25 per cent to $737 million, led by a rise in milk powder, butter, cheese, wool and cherries.
Exports to Australia, the second-largest market, advanced 11 per cent to $581 million, driven by gains in food preparations for infant use, paper and paperboard, milk powder, butter and cheese.
However, exports to the US, the third-largest market, slipped 9.5 per cent to $451 million, as beef fell 33 per cent in value and 23 per cent in volume.
