The AFR reports that APRA is so concerned about the crisis in insurance coverage in northern parts of Australia that it wants a new approach to the market: 

"All levels of government must act to save swathes of northern Australia from becoming uninsurable as a result of a climate change-related increase in natural disasters, the prudential regulator has warned. The Australian Prudential Regulation Authority said action should include a major shift of emphasis from disaster recovery to disaster resiliance and mitigation, pointing out the vast majority of disaster funding goes to "clean-up and recovery", with only 3 per cent on prevention and mitigation."

The piece by James Fernyhough is well worth a read, and not just for general insurers. It is also indicative of a wider interest by regulators in spotting medium to longer term issues and creating impetus for solutions where competitive pressure makes it hard for individual participants to act. That sounds a lot like some of the problems the New Zealand life insurance industry is grappling with.
