According to the report, Australian insurers collectively spend approximately $2.5 billion on reinsurance. Without this investment, they would need to hold an additional $70 billion in capital to meet their current capital levels. This substantial requirement would likely lead to significant increases in property premiums, reduce insurance availability, and complicate the work of brokers.

Kate Bible, chief actuary and head of capital for Aon’s Reinsurance Solutions in Australia and New Zealand, emphasised that without reinsurance, the market would struggle to serve consumers effectively. Reinsurance provides capital relief and stability in returns, enabling insurers to manage the financial impact of large-scale natural disasters.

As climate change contributes to more frequent and severe weather events, the reliance on reinsurance becomes increasingly vital. It allows insurers to spread risk and maintain solvency, ensuring that they can continue to offer coverage to consumers even in the face of significant claims.

For consumers, understanding the role of reinsurance can provide insight into the factors influencing premium costs. While reinsurance helps stabilise the market, the costs associated with it are ultimately reflected in the premiums paid by policyholders. Therefore, the interplay between reinsurance and premium pricing is a delicate balance that insurers must navigate to maintain both financial stability and affordability for consumers.
