New South Wales produces about 32,000 tonnes of onions annually. This figure represents 15 per cent of the total Australian production. About 90 per cent of the state’s onion crop is grown in the Riverina - the region from Griffith and Whitton in the north to Jerilderie in the south. There is also a small but expanding onion industry in the Central West around Wellington and south to Cowra.
