In the most recent financial year, ending on June 30, the grape crush was 1.6 million tonnes, down 7.5% on the previous year.
Australian Bureau of Statistics data said the crush produced 1.1 billion litres of beverage wine, down 3.4% on the 2009 figure. Red and rosé wine production was 613 million litres, down 1.7%, and white wine production 498 million litres, down 7.4%.
But exports of Australian wine were up 4.8% to 789 million litres. Domestic sales saw a similarly big increase and inventories fell 8.3% to 1.7 billion litres.
In the UK off-trade, Nielsen figures for the year to September show Australian wine volumes were flat, and sales value up 2%. Australia remains the market leader, way ahead of its closest rivals, Italy and the US.
