National Diagnostic Protocols (NDPs) are documents containing detailed information about a specific plant pest or group of plant pests to allow accurate taxonomic identification. They provide information on the pest(s), host(s), taxonomic status and the methods to detect and identify it based on the best available information. The newer protocols also include diagnostic information to support surveillance activities. In short, NDPs enable consistent identifications and increased confidence in diagnostic outcomes.
NDPs are an integral component of Australia’s plant biosecurity system. They are developed for use in Australia and endorsed by the Plant Health Committee.
NDPs are used by diagnosticians to identify plant pests:
Emergency diagnostic protocols – in the event of a pest incursion, an emergency diagnostic protocol can be developed if there is no NDP, an international protocol exists but is not considered suitable by plant health experts in Australia, or a NDP exists but an alternative protocol has since been developed which is considered more appropriate for diagnosing an pest. Emergency diagnostic protocols should be sent to SPHD for approval ([email protected]). Details of the use and approval of emergency diagnostics protocols is in Reference Standard 3.
The development and management of NDPs is overseen by the Subcommittee on Plant Health Diagnostics (SPHD) and administered by the NPD Coordinator and Plant Health Australia.
NDPs are drafted by NPBDN members that work in plant health laboratories, in conjunction with the NDP Coordinator.
The protocols must be developed according to SPHD Reference Standards, which include directions to the author on developing the protocol, review and verification processes and endorsement of the protocol.
The reference standards are:
Anyone wishing to develop a NDP should contact the NDP Coordinator to discuss the scope of the protocol and development requirements prior to commencement.

SPHD seeks ad hoc funding from different sources to contract laboratories to develop NDPs. When funding is available, proposals are sought from NPBDN members through the website.
If you already have funding and wish to develop an NDP for a specific pest or want to contract someone to develop a NDP for a specific pest, contact the NDP Coordinator at [email protected]
NDPs are available in the resources section of the NPBDN website. NPBDN members can also view the whole list of NDPs, draft NDPs and other relevant protocols here.
Contact the NDP Coordinator at [email protected], if you have any questions or want to discuss developing, validating or reviewing an NDP.
