Operating since 1939, the Nursery & Garden Industry Western Australia (NGIWA) is the voice for the WA nursery and garden industry. Contributing over $200 million to the Western Australian economy each year, the industry supports in excess of 200 grower nurseries, retail garden centres and allied trader manufacturers. The strategic plan of NGIWA is to encourage business improvement and determine strategies to assist businesses within the industry continue to grow.

NGIWA provides a professional network, industry representation and business development initiatives for Western Australian growers, wholesalers, retailers and allied traders. This support enables them to operate more effectively; providing the public with quality plants, garden design and installations, and related products and services. Like the nursery and garden industry at large, most NGIWA members are small, family-owned businesses that grow nursery and greenhouse plants, sell garden products, design, install and care for gardens, and sell supplies to the industry and public.
