Australia’s first National Climate Risk Assessment, released by the Albanese government, reveals that 1.5 million people living in coastal areas could face serious threats from sea level rise and flooding by 2050. The report highlights that climate hazards will not occur in isolation but in “cascading and compounding” ways, meaning storm surges, rising seas, and coastal erosion will strike communities, ecosystems, and infrastructure at the same time, amplifying risks.
The assessment warns that the impacts will escalate even under modest warming. For example, Brisbane could experience up to 86 days of coastal flooding each year by mid-century, which could rise to 314 days annually under higher warming scenarios. The economic toll is also stark: property losses could exceed AU$611 billion, with mounting costs for insurance, health systems, and infrastructure adaptation. These findings underscore the urgent need for long-term planning to protect Australia’s coastlines and communities. More
