Horticulture

The Department of Primary Industries and Regional Development works closely with all sections of the industry supply chain from paddock to plate.

Western Australia grows a diverse range of top-quality horticultural crops from the Ord River Irrigation Area in the north, to the Gascoyne River at Carnarvon, the coastal sands near Perth and throughout the cooler south-west region.

Crops include tropical and temperate fruits, delicious vegetables and outstanding table wines. WA also leads the country in flower exports, mostly from our unique native flora.
