Destructive shot-hole borer reaches Perth's far northern suburbs
News of the detection comes just over a week after the state government announced it would transition from eradicating to managing the pest, which was first detected in Perth in 2021.
The City of Wanneroo said they're working with the Department of Primary Industries and Regional Development to implement a Tree Management Plan for the affected tree - which is in the suburb of Wanneroo - and will keep a close watch on the area in the coming weeks.
Wanneroo Mayor Linda Aitken said the city is committed to taking swift action to prevent the pest's spread.
'The PSHB could significantly impact the City of Wanneroo's urban canopy if it were to become established here,' she said.
'It's important that we all check our trees for signs and report any suspected sightings, to allow DPIRD to investigate.
'Protecting and increasing our canopy cover and vegetation is a key goal for the City, as set out in our Urban Forest Strategy.'
As Perth's most northern metropolitan local government, the City of Wanneroo covers 685.8 square kilometres, stretching from Girrawheen to Two Rocks.
In the neighbouring council, the City of Joondalup has also confirmed three PSHB cases on council-managed land and is continuing to work with DPIRD to these infestations.
Following the decision to end eradication efforts, the State Government has committed an additional $62.6 million to biosecurity responses and $2.17 million to research projects to help curb and treat infestations, including chemical treatments aimed at managing the spread of the shot-hole borer.
WA Agriculture and Food Minister Jackie Jarvis believes the State has a strong foundation to manage the pest moving forward, as the infestation remains confined to the metropolitan area.
'We will continue to look for alternative solutions by supporting local scientists to undertake more research under WA conditions,' Ms Jarvis said.
'The more we can learn about this pest, the better equipped we will be to protect and support our State's tree canopy and agricultural industry.'
For more information on PSHB and the signs to watch for, DPIRD is encouraging residents to visit their website and use the MyPestGuide app to report any suspected sightings.

Kimberley pharmacy workers encouraged to train to fill rural GP gap
Local pharmacists are being encouraged to take up subsidised training for a graduate certificate in pharmacy prescribing in an effort to tackle the rural GP shortage. The call from Health Minister Meredith Hammat comes after the State Government announced up to 80 community pharmacists would undergo training to begin diagnosing more ailments from late 2026 in a bid to ease pressure on GPs, expanding a trial that currently allows pharmacists to manage contraceptive pills and diagnose and treat urinary tract infections. Visiting Kimberley Pharmacy Services on Thursday, Ms Hammat said her trip was about liaising with local services to encourage participation. 'We're really keen to ensure that people in regional WA, consider taking part in the graduate certificate training so that they can be a part of the pilot when it rolls out in the second part of next year,' she said. 'We know it can be difficult for people, particularly in regional areas to get access to a GP, so what we want to do is provide more access for Western Australians and more choice so that when people need to get treatment for everyday health conditions, they are able to come and see their community pharmacists.' The training for a graduate certificate in pharmacy prescribing will take six to 12 months to complete and will be delivered by WA universities. Training will also be subsidised up to $12,000 for some participants, according to the Minister. 'One of the really important things that we've also included as part of this program is a commitment in this year's State Budget for $1.26 million to make available subsidies for some of the people that apply to do that training,' Ms Hammat said. A 12-month pilot program will roll out in the second half of 2026, which will also see the scope of practice for community pharmacists expand to include programs to help people quit smoking. Kimberley Pharmacy Services managing partner Hannah Mann said rural pharmacies play a central role in providing healthcare for their communities. 'We want to offer more to our communities and we want to be part of the health services that are available,' she said. 'We see a lot of patients that we have to send to the hospital or to an urgent care clinic to get a prescription, so I think being able to actually offer that full service without having to send patients away who then come back with a prescription anyway is great.' She said the subsidised training would go a long way for rural participants. 'When you're coming from a rural and remote area, training can be a big undertaking,' Ms Mann said. 'You might be taking time off work, organising childcare, travel, needing to pay for airfares to participate in face-to-face training. 'So we really appreciate the State Government and the Health Department's acknowledgement that the cost of the participation if you're from a rural and remote area are substantial, and for recognising that we are a really important part of the health picture in rural and remote areas.' It comes as Broome continues to suffer from a GP shortage, with waiting times for an appointment at the only remaining clinic in town regularly exceeding a month. Ms Hammat said she was aware of the shortage across regional WA and is working with the Federal Government to make GP access more equitable. 'We are regularly talking to the Federal Government about what more they can do to support GPs,' she said. 'They do control a lot of the settings for GPs, both in terms of the new key rebates that are available and some of the things that might impact on internationally trained doctors coming and working in regional areas. 'So we'll continue to advocate for the Federal Government to do as much as we can to make sure there is a strong network of GPs in the State.'

Feral deer to be culled across 1000sqkm area near Esperance and Harvey
A feral deer population of about 1500 will begin to be culled across southern WA next week after being identified through aerial surveillance and thermal imaging technology. Agriculture Minister Jackie Jarvis told State Parliament the project had covered 660sqkm near Esperance, 440sqkm near Harvey, and 41sqkm near Muchea during the past two years. More than 1500 feral deer were identified in the three targeted areas— with about 660 feral deer found near Esperance, about 700 near Harvey, and about 170 near Muchea. The Department of Primary Industries and Regional Development will start localised aerial control for feral deer in the Esperance and Harvey areas next week. A spokeswoman for Ms Jarvis said WA was in a 'unique' position to control feral deer populations while they were still 'relatively small and localised'. 'Feral deer populations in WA have the potential to grow quickly and are an emerging pest threat, impacting agricultural production, important environmental values and sensitive areas,' she said. 'Like many pests, deer tend to prefer areas on the fringe of bushland and farmland, where they can graze in paddocks but retreat to cover if startled.' A declared pest, feral deer damage the WA environment and agriculture industry by grazing on native plants, competing with native fauna for food and habitat resources, impact water quality and soil properties, and damage pasture, commercial crops and orchards. They also act as carriers for diseases and pathogens such as foot-and-mouth disease, and can transmit exotic livestock diseases to cattle, sheep, and goats. The aerial control will take place across Crown land and over a small number of private rural properties. DPIRD has liaised with affected landholders to plan control efforts. 'During the past two years, DPIRD has undertaken aerial thermal surveys targeting agricultural and conservation areas where there are known populations of feral deer,' the spokeswoman said. 'The information gathered is aiding the development of tools and management strategies to develop best practice control measures.' Australia is home to more than 1.5 million feral deer, the population exploding from about 80,000 in 1980. DPIRD has been assisted by the Department of Biodiversity, Conservation and Attractions with deer research initiatives, surveys, and control program activities. 'Thermally-assisted aerial control is an effective method for reducing deer populations across a landscape,' the spokeswoman said. She said any future control would be determined by the success of the current program and DPIRD was continuing to liaise with rural landholders near Muchea to plan for local aerial control activities in early 2026. Landholders who see vertebrate pests, such as feral deer, on their property can report sightings using the FeralScan App or online at .

Long-awaited Broome Sobering Up Centre tender up for grabs
The State Government has officially released a tender for the construction of Broome's long-awaited Sobering Up Centre, more than three and a half years after asbestos contamination forced the closure of the town's previous facility. That closure left the Kimberley's largest community without a fully functioning service amid a worsening alcohol abuse crisis. The forward works contract, now open for submissions, covers site clearing, earthworks and essential infrastructure at the Napier Terrace location, marking the first concrete step towards restoring a vital service aimed at providing safe care for people affected by alcohol. Broome's previous sobering-up facility, known as the Walangari Shelter, was shut down in October 2021 after asbestos was discovered on-site. Since then, a temporary centre near Milliya Rumurra Rehabilitation Centre has operated with just 12 beds — less than half its original capacity — despite ongoing community demand. The tender comes as the State Government moves to make the Banned Drinkers Register permanent in the Kimberley under new legislation. Following the announcement, community leaders expressed concerns about the lack of alcohol and other drug (AOD) services in the region. Former Shire of Derby/West Kimberley President Peter McCumstie said without proper investment in treatment and rehabilitation, harm minimisation measures like the BDR risked making the situation worse. 'We see little to no increase in resources to the only alcohol and drug rehabilitation centre outside of Broome or significant increased resources to assist community-led efforts to work with those being placed on the BDR,' he said. 'Unless this changes, a permanent BDR will only serve to cause more issues and problems in our Kimberley towns and communities.' A government-commissioned review by Deloitte Access Economics into the BDR found no increase in the use of AOD services since its introduction, but noted that limited access to treatment might be discouraging people from seeking help in the first place. The Broome Chamber of Commerce and Industry has also raised concerns over the proposed location of the new sobering-up centre, warning that while the service is necessary, its placement closer to the town centre must be carefully balanced with Broome's business and tourism economy. 'While the chamber supports the establishment of the service closer to town, this must be balanced with the interests of the business and tourism sectors to ensure Broome continues to thrive as a destination and economic hub,' the chamber said in its submission on the proposed location to the Mental Health Commission earlier this year. Tenders close on July 30, with forward works expected to commence later this year.
