Production nurseries

The Nursery and Garden Industry Australia represents the biosecurity interests of the industry. They are members of Plant Health Australia and signatories to the Emergency Plant Pest Response Deed. Their responsibilities include:

  • biosecurity planning and implementation at the national and farm levels
  • liaising with federal and state governments on trade issues
  • funding and supporting biosecurity initiatives
  • participating in national committees and response efforts in an emergency.

Industry overview

In 2014–15, nursery production (propagation stock, vegetable and forestry seedlings, bedding plants, indoor plants, fruit and landscape trees and shrubs) was valued at $664 million (LVP). The nursery industry operates in all states and territories, being one of the largest and most diverse plant industries in Australia.

The industry estimates an annual gross production value of approximately $2.5 billion (production nurseries only) in 2016 across the entire supply chain. NGIA supplies to ornamental retail, landscape, re-vegetation, rehabilitation and production horticulture sectors including tree crops (e.g. fruit, forestry, tea tree), vegetables, forestry and cut flowers. The industry has a limited export focus of approximately $18 million annually; however there is ample opportunity for international export growth.

In 2016 NGIA developed the Nursery Production Farm Management System website which will be the one-stop shop for industry biosecurity
for growers including access to pest fact sheets, management plans, videos, BioSecure HACCP and a training portal.

The national plant health project Building the Resilience and On-Farm Biosecurity Capacity of the Australian Production Nursery Industry (2015–2020) will continue to develop plant biosecurity resources and to upskill industry members and expand knowledge. Extension videos covering topics such as site surveillance, intake inspection and crop monitoring have been developed since 2013, with NGIA and PHA working together in 2016 to produce six to eight new biosecurity videos annually through to 2019.

The industry continues to build the online electronic plant pest identification resource Pest ID Tool which combines information and images on endemic and
key exotic plant pests that impact on production or trade.

The nursery industry is covered by version 3 of the biosecurity plan for the nursery industry and the Biosecurity Manual for the Nursery Production Industry Version 1.

Production nursery IBPIndustry Biosecurity Plan for the Nursery Industry

Biosecurity planning provides a mechanism for the production nursery industry, government and other relevant stakeholders to assess current biosecurity practices and future biosecurity needs. Planning identifies procedures that can be put in place to reduce the chance of pests reaching our borders or minimise the impact if a pest incursion occurs.

The Industry Biosecurity Plan for the Nursery Industry outlines key threats to the industry, risk mitigation plans, identification and categorisation of exotic pests and contingency plans. For a copy, please contact PHA on 02 6215 7700 or email

Nursery & Garden Biosecurity ManualBiosecurity Manual for the Nursery Production Industry

The Biosecurity Manual for the Nursery Production Industry contains information to help producers to implement biosecurity on-farm. Manuals usually contain an overview of biosecurity, fact sheets to identify the high priority pests of a crop, tips on crop management, and how to manage people, vehicles and equipment to minimise biosecurity risks. Manuals also contain a biosecurity self-assessment list, and templates to record pest surveillance records and visitors.

More information about on-farm biosecurity for both plant and livestock producers is available from the Farm Biosecurity website.

Exotic pests (not in Australia)

The following is a list of high priority exotic pests of production nurseries. These pests were identified during the development of the Industry Biosecurity Plan for the Nursery Industry in consultation with industry, government and scientists. They have been assessed as high priority pests based on their potential to enter, establish, and spread in Australia (eg environmental factors, host range, vectors) and the cost to industry of control measures.

PHA has a range of fact sheets, contingency plans and diagnostic protocols relevant to these pests. Pest risk review documents are also available for some pests. Please contact PHA on 02 6215 7700 or email for more information.
