Australia's grape glut shows no signs of disappearing, with official figures this year pointing to another bumper harvest.

The Australian Bureau of Statistics said estimates for 2005 match the record 2m tonnes produced last year.

The wine industry is enjoying strong export volumes but the oversupply of produce means growers are suffering from falling grape prices.

The biggest producing state, South Australia, recorded a drop in production of 3% this year, to 861,500 tonnes.

Victoria and New South Wales, the next largest growing states, showed increases in production - up 4% to 551,200 tonnes, and by 5% to 508,300 tonnes respectively.

Red grape production, at 1m tonnes, is slightly higher than the white grape production of just under 980,000 tonnes.

Around 1.8m tonnes of grapes have been harvested for winemaking.
