Programs & projects

Increasingly, Plant Health Australia is being recognised for its ability to bring stakeholders together and achieve critically important outcomes for plant health in the national interest. PHA is currently involved in the following national programs and projects.


Citrus Biosecurity Program

The Citrus Biosecurity Program is an initiative to improve the management of, and preparedness for, biosecurity risks that threaten the citrus industry.

Farm Biosecurity Program

The Farm Biosecurity Program provides information on practical, cost-effective measures that producers can implement on farm to reduce the risk of pests and disease.

Fruit Fly

Fruit flies are a large and important group of insect pests that attack a wide range of fruit and vegetables globally. In Australia, the presence of some species of exotic fruit fly could reduce the capacity to trade in domestic and international horticultural markets.

Grains Farm Biosecurity Program

Grains Biosecurity Officers are located in most states through the Grains Farm Biosecurity Program, which is delivered by PHA and funded by growers through the Grain Producers Australia together with the governments of Western Australia, Queensland, Victoria, South Australia and New South Wales.

Melon Biosecurity Program

The Melon Biosecurity Program is an initiative to improve the management of, and preparedness for, biosecurity risks in the Australian melon industry at the farm and industry levels. Since 2018, the program has operated under a memorandum of understanding between PHA and the Australian Melon Association (AMA). It is funded by growers through the Melon Plant Health Australia (biosecurity) levy. A Melon Biosecurity Officer employed through the AMA represents the industry at all levels of government and industry on biosecurity matters, and develops and delivers information to raise biosecurity awareness among growers and other industry stakeholders.

Vegetable and Potato Biosecurity Program

Plant Health Australia has joined with industry member AUSVEG to run the Vegetable and Potato Biosecurity Program. The program, which is funded by grower levies, aims to increase the awareness of growers about the importance of using on-farm biosecurity measures to protect their crops from pests and diseases.

National Bee Biosecurity Program

The aim of the National Bee Biosecurity Program is to help beekeepers to manage pests that are already in Australia, and to prepare for incursions by exotic pests.

National Bee Pest Surveillance Program

The National Bee Pest Surveillance Program is an early warning system to detect new incursions of exotic bee pests and pest bees. The program involves a range of surveillance methods conducted at locations considered to be of most likely entry of bee pests and pest bees throughout Australia.

National Forest Pest Surveillance Program

Overseas pests, global travel and trade have led to new pest establishments threatening Australia’s forests. A National Forest Pest Surveillance Program has been established to help reduce the environmental, social and economic risks of exotic pests to forests.

Weed management

Weeds are a significant biosecurity issue that affect all Members of PHA, reducing yields and costing Australian producers a vast amount of time and money. Substantial resources are invested by a diversity of organisations to manage weeds on a local, regional and national level. Conservatively, it has been estimated that the total annual economic cost of weeds to Australia is over $4 billion.
