About ParaBoss

ParaBoss is the national authority for sheep, goats and cattle parasite control in Australia, providing information on parasites and their control through its suite of products – WormBoss, FlyBoss, LiceBoss and TickBoss. The resources are a source of detailed information and regional programs developed to improve on-farm management of worms, flies, lice and ticks.


ParaBoss is currently in its third phase.

In Phase I (2013-2016) WormBoss and FlyBoss were developed by the Sheep CRC, whilst LiceBoss was developed by Australian Wool Innovation (AWI). When the initial development phase of these resources was completed, an ongoing home was needed to manage and improve them. To do this, the Sheep CRC created the ParaBoss project and in 2016 licenced its share of the ParaBoss intellectual property (IP) to the University of New England (UNE).

Phase II (2016-2021) of the project, delivered by UNE, with funding provided by AWI and MLA, was to maintain and improve the existing ParaBoss products. A separate project funded by MLA and delivered by the Queensland Department of Agriculture and Fisheries, developed TickBoss. At the end of Phase II, it was agreed that AWI, MLA and UNE all jointly shared ownership of the WormBoss, FlyBoss and LiceBoss IP, whilst MLA and UNE jointly shared the TickBoss IP.

The Website Management and Producer Communication, Extension and Adoption components of Phase III (2021-2024) of the project is delivered by AHA, funded by MLA and AWI, with contribution from AHA.  Under the current phase, UNE are responsible for Advisor Training, including the WEC Quality Assurance program.  

Governance and technical input

A ParaBoss IP Owners Committee, consisting of MLA, AWI and UNE representation, oversees the strategic direction of ParaBoss.

A ParaBoss Project Committee, consisting of AWI, MLA, UNE and AHA representatives, along with an independent parasitologist (Dr Brown Besier) provides operational direction to ParaBoss.

ParaBoss Technical Committee ensures the content provided to industry is independent, proven and practical.

Function, Role and Membership of the ParaBoss Technical Committee

The ParaBoss Technical Committee, which operates as an advisory body to the ParaBoss Project Committee, represents the livestock industries, and operates in the interests of producers and their livestock. In doing so, the ParaBoss Technical Committee has primary responsibility to producers, providing technical input to the ParaBoss Project Committee on behalf of the sheep, goat and beef cattle industries of Australia.

In its capacity as an advisory body to the ParaBoss Project Committee, the Technical Committee will:

  1. Review technical accuracy of existing and new ParaBoss information, content, tools and programs.
  2. Identify emerging issues and extension needs for inclusion in communication or extension programs, on the basis of new technical information and industry trends.
  3. Facilitate engagement with the broader sheep, goat and cattle parasite technical community.


ParaBoss as a program provides industry leadership for ruminant livestock parasite management through its respected brands, a strong and independent technical foundation, extensive industry networks and well-used industry web sites. It currently has:

  • An independent Technical Committee of industry professionals to ensure the technical accuracy of ParaBoss information, programs and tools
  • An extensive and active network of industry professionals and service providers
  • WormBoss, FlyBoss, LiceBoss, and TickBoss websites, which contain best practice information and tools for sheep, goats, and cattle
  • ParaBoss Boss Bulletin (an e-newsletter)

  • ParaBoss monthly webinars for industry professionals
  • Producer training materials provided as online self-directed learning
  • Materials that support other industry groups and extension programs
