Given that water is such a valuable resource to the area, growers have adapted innovative techniques to using water that have therefore made themselves some of the most efficient in Australia. Crops are grown on micro drip irrigation using water from below ground aquifers. The dry subtropical climate makes Carnarvon suitable to grow an extraordinarily wide range of temperate, tropical and subtropical produce across the seasons.
The majority of horticulture activity is carried out along the banks of the Gascoyne River very near to the town of Carnarvon on 170 plantations covering and area of 1,500 hectares. The most significant crops in volume and value are bananas, tomatoes, table grapes, capsicum and mango.
