Climate Change Threatens Australian Suburbs with Unaffordable Insurance

Properties identified as high-risk are likely to encounter skyrocketing insurance costs, according to the report commissioned by the Climate Council. Karl Mallon, the founder of Climate Valuation, emphasized the immediacy of the threat posed by climate change, urging decision-makers to address the concerning statistics detailed in the research.

The climate group's modelling identifies 86 suburbs as "critical climate risk zones," wherein 80% to 100% of properties are at risk of becoming financially uninsurable if current trends persist.

The escalating risks and rising cost of insuring these properties underscore the broader financial repercussions of climate change on Australian communities. The Insurance Council of Australia (ICA) has noted that insurers have long cautioned about these escalating risks, tying rising insurance premiums to extreme weather events, which have resulted in $4.5 billion insured costs annually over the past five years. This marks a nearly 70% increase compared to the previous five-year period, with projected costs reaching $35 billion by 2050 if no mitigating actions are undertaken.

The report highlights the potential backlash on the economy if insurance becomes inaccessible, with valuable community resilience being the key to maintaining affordability and availability of coverage.

The ICA advocates for significant investments in resilience and mitigation, such as a proposed $30 billion investment in flood defenses. It also urges the removal of unfair state insurance taxes and the promotion of household resilience measures, which some insurers already incentivize through premium reductions.

Climate Valuation additionally suggests several measures including retrofitting homes, relocating properties in extreme cases, halting development in high-risk areas, and ensuring that new constructions are climate-resilient as per the National Construction Code adaptation. These steps, it argues, would not only protect communities but also relieve pressure on insurance premiums, delivering what they describe as a "double dividend."

The report calls for a comprehensive integration of "climate proofing" into national standards to prevent placing more Australians in harm's way and to foster the development of sustainable, resilient infrastructure.
