Canola

Western Australia is the major canola growing state in Australia producing about 40% of the nation’s 2.7 million tonnes each year.

The majority of WA canola is exported – generating about $0.6 billion for the state’s economy each year, with the Netherlands, Belgium, Germany and Japan WA’s largest export canola markets.

WA canola is renowned for its high oil content – with the state consistently achieving higher oil contents than the rest of the nation.

The Department of Primary Industries and Regional Development supports the WA canola industry through agronomic research and development; and pest and disease identification and management.
