Mark Leplastrier

General Manager

With over 24 years of experience in natural hazard risk assessment, Mark helps organisations anticipate, assess, and mitigate the impacts of natural perils and climate change. Specialising in the design and integration of risk models and climate strategies, Mark supports resilience across insurance, banking, energy, government, and beyond. 

Mark’s expertise spans risk-based pricing, catastrophe loss modelling, reinsurance strategies, natural peril budgeting, and major event response. Since the early stages of his career, Mark has led research initiatives aimed at deepening the understanding of how climate change is influencing the frequency and severity of extreme weather. These insights have enhanced risk modelling, improved planning, and strengthened adaptation strategies across multiple sectors. 

Mark has played a pivotal role in national-scale projects focused on enhancing Australia’s resilience to extreme weather. This includes leading initiatives for one of the country’s largest insurers, as well as contributing through various committees of the Insurance Council of Australia to support industry-wide efforts in making homes and businesses safer in a changing climate.

Through collaboration with major industry bodies, boards, and senior leaders, Mark has helped develop resilience frameworks and inform catastrophe risk management.

Interested in Learning More About Our Detailed Australian Bushfire & Grassfire Loss Model?

The latest release of FireAUS, modelling bushfire and grassfire risk across Australia, represents another leap forward in the quantification of risk at the location and portfolio level. Risk Frontiers are the local, Australian-based experts and have used our recognised artificial intelligence, machine learning and climate modelling capabilities, decades of peer reviewed research and on the ground post-event surveys to continue to evolve our leading edge fire loss model.


Soon to be released FireAUS 4.0 will continue from FireAUS 3.2’s Australia wide coverage at the individual address level and can report losses at address level, SA1, postcode, and Cresta zones.


Our team is ready to answer your questions.
