Understanding Catastrophe Modelling

Protecting your assets before the storm hits:

As extreme weather events become more frequent and unpredictable, businesses need more than insurance - they need insight.

Catastrophe modelling brings together science, engineering, and financial data to simulate how natural hazards like floods, cyclones, and bushfires could impact your assets. This forward-looking approach helps businesses across Australia and New Zealand understand their exposure, reduce uncertainty, and build resilience into their insurance strategies.

Whether you're managing a commercial property portfolio, infrastructure, or industrial sites, Lockton’s catastrophe modelling services can support smarter decisions - before, during, and after a weather event.

Our capabilities include:

  • Flood risk analysis and high-resolution mapping

  • Probable Maximum Loss (PML) and Average Annual Loss (AAL) insights

  • Scenario testing based on historic and forecast events

  • Real-time event simulations for rapid response

  • Climate scenario modelling aligned with ESG and regulatory reporting
