HR leaders face the challenge of balancing safety, productivity and climate adaptation
Australia’s rising temperatures and escalating natural disasters are no longer just environmental or economic issues — they’re reshaping the world of work. As the country experiences record heat, more intense floods and fires, and mounting insurance losses, the toll on workers’ safety, productivity and wellbeing is becoming impossible to ignore.
According to the Insurance Council of Australia, extreme weather events now cost the nation about $4.5 billion in insured losses every year — almost three times what they did in the 1990s. But behind those figures lies another story: the human cost of working in a climate that’s becoming harder to endure.
Andrew Hall, chief executive of the Insurance Council, said the rising losses reflected compounding pressures on communities.
“While Australia has always faced extreme weather, the accelerating losses per person and their compounding impact on communities is costly and ongoing,” he said following the release of new data on the cost extreme weather.
“Each decade is costlier than the last.”
The heat on Australia’s workforce
That cost isn’t just measured in dollars. It’s also showing up in declining productivity, higher absenteeism, and greater health risks across a range of industries. Outdoor workers — from construction crews and farmhands to emergency services and delivery drivers — are on the front lines.
Research from the CSIRO has found that productivity can drop by between 2 and 3 per cent for every degree above 20°C.
For agricultural workers, this means longer rest breaks, shorter working hours and a greater likelihood of heat-related illness. Principal economic research scientist at CSIRO Katie Ricketts said that under a 2°C warming scenario, horticulture alone would require roughly 4 per cent more labour to maintain current yields.
“If heat makes farm work more difficult and dangerous, that could affect worker attraction and retention and have bigger ramifications for overall labour supply and demand,” Ricketts said in a recent CSIRO article.
For HR and workplace safety teams, that means adapting not only physical conditions but also job design, scheduling and workforce planning. Heat stress, once a seasonal issue, is now a year-round risk.
Health, safety and the limits of adaptation
The World Meteorological Organization confirmed that the past decade was the hottest on record. That’s already creating measurable health consequences.
A study from Monash University found more than 1,000 Australians died during heatwaves between 2016 and 2019.
As cities grow hotter, workers in dense urban areas are feeling the effects too. New data from RMIT University shows that parts of western Sydney and outer Melbourne rank among the most heat-vulnerable in the country. The index combines factors such as age, income, disability, and access to green space to identify where people are least able to cope with heat.
Dr Melanie Davern, director of the Australian Urban Observatory, said heat vulnerability was complex and widespread. “It’s not just people living in disadvantaged areas that are going to be heat vulnerable,” told The Guardian. “It actually applies across the country.”
That complexity is mirrored in the workplace. Older workers, those with pre-existing conditions, and employees in lower-paid or physically demanding jobs are at particular risk. The problem is compounded by socioeconomic inequality: those who can least afford air conditioning or flexible hours are often those most exposed to the elements.
Managing work in a warming world
HR professionals are now being drawn into a challenge that sits at the intersection of safety, productivity and climate adaptation. The traditional approaches — providing shade, hydration and protective gear — are increasingly insufficient on their own.
Experts are calling for new approaches to managing work during extreme heat, including shifting working hours to cooler parts of the day, redesigning tasks to reduce physical strain, and updating occupational health standards. But each solution comes with trade-offs: earlier start times can raise fatigue risks, while increased rest breaks can reduce output and strain wages.
Ricketts warns that small businesses and family-run operations may struggle to afford these adaptations, particularly in regional areas where labour shortages are already severe.
“The danger is that only large agribusinesses will be able to afford those adaptations,” she said. “We don’t want a two-speed agriculture system where small and medium growers are left behind," she said.
For HR teams, this underscores the need to balance operational requirements with worker wellbeing and retention. As Australia’s workforce ages and the climate becomes harsher, employee health and safety will increasingly shape productivity, insurance premiums, and even employer reputation.
A shared responsibility
Experts agree that climate adaptation is no longer optional. It requires coordination between employers, governments and workers themselves. Some state governments are already considering reforms to emergency services levies and workplace safety regulations to ease financial and compliance pressures.
But on the ground, it’s HR managers who will bear much of the responsibility for implementation — revising policies, educating workers, and planning for a hotter future.
The data makes one thing clear: as temperatures climb and weather extremes intensify, Australia’s labour market will face pressures unlike any before. Employers can no longer treat climate impacts as an externality. They’re becoming a defining feature of the modern workplace — and the workforce of the future will depend on how effectively we adapt.
