Shire of Mundaring acknowledges the recent announcement by the National Management Group (NMG) that the coordinated response to the Polyphagous Shot-Hole Borer (PSHB) has now officially moved from an eradication phase to long-term management.
This national decision, informed by scientific advice and biosecurity experts, confirms that eradication is no longer feasible. Management of the pest will now be led at the Federal level, with the Department of Primary Industries and Regional Development (DPIRD) continuing as the key agency in Western Australia.
Shire of Mundaring President Paige McNeil said the decision marks a critical turning point for the region and its natural environment.
“Our Perth Hills’ biodiverse environment is at a critical crossroad, with confirmation from the State Government that the infestation of Polyphagous Shot-Hole Borer can’t be eradicated and instead will need to be under a long-term management plan,” she said.
“This confirmation is especially concerning for Shire of Mundaring, as we are the environmental stewards of a vast region of mature forest and an internationally recognised biodiversity hotspot already under considerable ecological pressure from recent bushfires and the 2023–24 summer drought.
“So far, we've been lucky, no infestations have been confirmed within our Shire. However, we recognise and support the continued efforts of DPIRD and urge residents to remain alert to signs of the borer so we can all contribute to protecting our local environment.
“The borer’s confirmed long-term threat reinforces the importance of preserving our tree canopy and maintaining the health of our ecosystems.”
The Shire remains part of the designated Quarantine Area and will continue to collaborate closely with DPIRD to ensure community awareness, support local compliance, and help slow the spread of the pest. The Cook Government has committed $26.5 million in the 2025–26 State Budget to support the ongoing PSHB response, as well as $2.17 million for new research into control measures, and further investment in urban tree canopy initiatives, including the WA Tree Recovery Program and Treebates.
Residents are encouraged to stay informed and to continue reporting any signs of the borer through DPIRD’s MyPestGuide platform at mypestguide.agric.wa.gov.au, and to check the interactive map at dpird.wa.gov.au/pshb to understand local restrictions and identification tips.
