Tackling one of WA’s most urgent biosecurity threats – together.
On 31 July 2025, the WA Agricultural Research Collaboration (WAARC) hosted its Polyphagous Shot-hole Borer Research (PSHB) Symposium at Curtin University’s beautiful heritage building in St Georges Terrace, Perth.
The Symposium brought together about 90 leading scientists, policy-makers, WAARC members and partners for an invite-only event focused on research to limit the spread of PSHB.
With an opening address from Hon Dr Parwinder Kaur MLC, the Symposium was a chance to learn more about three new collaborative research projects, supported through $2.17 million in funding from WAARC:
- The University of Western Australia project is investigating cutting-edge chemical and biological treatments to control the pest, alongside improved lure systems and community surveillance.
- Murdoch University’s project explores the fusarium fungus associated with polyphagous shot-hole borer, examining its host range in WA to support targeted containment and control in WA. ArborCarbon is partnering on this project, applying advanced tools like remote sensing, geospatial mapping and artificial intelligence to help detect infestations early – a crucial step in protecting our environment.
- The Curtin University project is developing predictive models and risk maps to guide surveillance, improve decision-making and ensure effective use of resources.
All three projects are being delivered in collaboration with each other and the Department of Primary Industries & Regional Development (DPIRD), aligning with the recent shift in approach from eradication to long-term management of PSHB.
Together, these initiatives aim to contain the pest, enhance early detection and improve the State and National biosecurity response.
The day also included a panel discussion with research leads, exploring key questions like:
- What outcomes can stakeholders expect from the research and how will it support PSHB management?
- How can local governments and industry support the projects and get involved?
- What opportunities exist for students to participate or express interest?
Many participants took the opportunity to stay for networking, drinks and canapes after the Symposium, building connections and continuing the insightful discussions covered during the afternoon.
