Grapes & wine

Western Australia is a notable fine wine producer. Grapes grow in diverse areas of the South West including Margaret River, the Swan Valley, Great Southern, Pemberton, Manjimup, Geographe, Blackwood Valley, Peel and Perth Hills.

The Department of Primary Industries and Regional Development works closely to support industry and sponsors a trophy for the best regional wine at the prestigious Qantas Wine Show.

WA represents just 5% of Australian production but more than 20% of national fine wines. Exports are growing and China is an important market. 

Table grapes are grown from Carnarvon to the south-west and seedless varieties are most popular.
