Plant Health Committee (PHC)

PHC is the peak government plant biosecurity policy and decision-making forum. Its role is to maintain or improve plant health in Australia in support of the economy, environment and community through strategic policy, technical and regulatory advice and national leadership on plant biosecurity matters. PHC has responsibility for delivering on national priority reform areas, including those identified for implementation of the Intergovernmental Agreement on Biosecurity (IGAB) and oversighting the implementation by governments of the National Plant Biosecurity Strategy (NPBS).

In October 2011, at the request of the National Biosecurity Committee (NBC), PHC assumed responsibility for environmental matters including in relation to invertebrates that are terrestrial or freshwater herbivores, pollinators, parasites or parasitoids of plants, vectors of plant pathogens, or impact on social amenity.


The principal objective of PHC is to improve plant biosecurity outcomes, manage plant biosecurity risks and facilitate domestic trade within Australia through national leadership, strategic direction and collaboration with stakeholders.
