Insurers are monitoring heat risk in Western Australia as the Bureau of Meteorology (BoM) signals severe to extreme heatwave conditions for northern and central regions, with temperatures forecast to approach 50C.
The highest temperatures are forecast across the Pilbara and Kimberley, extending into interior districts over several days, according to BoM meteorologist Miriam Bradbury. “We’re expecting really, really hot conditions in northern areas and pushing down to the interior and across to the Pilbara,” Bradbury said, as reported by Perth Now. She said the expected temperatures would be substantially higher than long-term averages for this time of year. “As we go through the end of the week and push towards the weekend, we’re going to see the difference from the average pushing up to eight, possibly 10C above average,” she said.
Daytime temperatures in the mid to high 40s are forecast across large parts of the Kimberley and Pilbara, with overnight minimums remaining at or above 30C. “With the really hot days and those hot nights continuing, that’s when the heatwave concerns start coming into play. We do have pretty widespread and severe to extreme heatwave conditions building across those northern parts of the state,” Bradbury said. Authorities have raised concerns about heat stress in exposed communities, particularly given the duration of the event. For general insurers, prolonged heat and sustained high overnight temperatures may affect claims linked to heat-related illness, power and cooling system strain, equipment failure, business interruption, and agricultural losses in parts of the state with limited adaptive capacity.
While northern WA faces extreme temperatures, Perth is expected to experience conditions closer to typical summer ranges. Bradbury said the city would see a brief period of hotter weather before a trough moderates temperatures into the weekend. “[On Jan. 14], we’re looking at 33 degrees with a good burst of heat coming through, with [Jan. 15] getting up to 36, but by the time we get to the weekend, we get a west coast trough moving inland,” Bradbury said. The BoM outlook for Perth points to mostly sunny days with maximums generally between the mid-20s and high 30s over the coming week. For insurers, the near-term heat-related exposure is therefore more concentrated in regional and remote areas of WA than in the capital.
In Victoria, weather conditions in previously fire-affected locations have eased, with cooler temperatures and lighter winds expected to make firefighting and recovery work less difficult. “The more friendly conditions will hopefully make things less challenging for the firefighters continuing to fight those blazes across the state,” Bradbury said. The easing conditions in Victoria may reduce immediate bushfire pressures, but insurers remain exposed to seasonal swings if higher temperatures and stronger winds return later in the summer.
The heatwave alert in WA comes amid warnings from the Australian College of Rural and Remote Medicine (ACRRM) that continuing extreme weather across Australia is adding to health risks in rural, remote, and First Nations communities and increasing demand on local health systems. ACRRM president Dr Rod Martin said persistent patterns of flooding, heatwaves, and other severe events are already influencing health outcomes outside metropolitan areas and may have long-term effects. “Australia’s often wild weather increases the risk of serious illness and injury, particularly for people with chronic conditions, older Australians, and those with limited access to care. We are seeing higher demand on health services for heat-related illness, dehydration, injury, and mental health support, and these pressures do not end when weather conditions ease,” Martin said.
Martin said rural and remote health services often act as the first, and sometimes only, point of care during extreme events, which makes their capacity and resilience a key consideration. “In many rural communities, local health services are operating with limited workforce capacity yet are expected to respond to prolonged emergencies and support recovery,” he said. For health, life, and income protection insurers, higher presentations for heat-related illness, worsening of chronic conditions, and mental health needs may influence claims frequency, duration, and cost in climate-exposed regions. These patterns are relevant to underwriting assumptions, pricing approaches, and product design for portfolios with significant rural and remote exposure.
Martin highlighted the role of rural generalists in emergency response and recovery and said he wants these clinicians to be more integrated into official planning frameworks. “We continue to call on governments, emergency management agencies, and councils to ensure rural generalists are formally included in disaster response and recovery planning. They have the skills, the local knowledge, and the care that communities rely on during and after extreme weather,” he said.
Martin also pointed to the need to support the medical workforce itself to maintain service continuity when communities are affected by extreme conditions. “Rural doctors are part of the communities they serve and are often impacted by the same events while continuing to provide care. Protecting the health and wellbeing of the rural workforce is fundamental to protecting the health of communities where their vital services are provided,” he said. For insurers and intermediaries, the Western Australian heatwave and broader extreme weather patterns highlight links between physical climate hazards, health system strain, and community resilience. These factors form part of catastrophe planning, reinsurance strategy, and risk advisory work across Australia’s insurance market.
