Landcare Tasmania, in partnership with CSIRO, invites farmers, Landcare groups, First Nations communities, stakeholders and anyone working to manage invasive weeds to join this online webinar to learn more about the new nationally approved biocontrol solutions for African Boxthorn. Led by CSIRO, this session will provide an accessible overview of the science, safety, and practical application of biocontrol for these major weeds. Participants will learn how the new African Boxthorn rust fungus biocontrol (Puccinia rapipes) will be rolled out across Tasmania between 2026–2027, how it works, and how Tasmanian land managers and community groups can get involved. The webinar will also cover current and past work on Sea Spurge biocontrol to support coastal restoration. Photo credit: CSIRO
