Hollyman will join Gallagher Re from Aon in April 2026. At Aon, he was most recently Asia Pacific head of casualty for Aon Reinsurance in Sydney.
He brings decades of industry experience to the role, having joined Aon Benfield (now Aon Reinsurance Solutions) in 2011 as head of casualty insurance for Australia and New Zealand.
Prior to joining Aon, he held the same position with Guy Carpenter in Marsh’s reinsurance division for six years, and prior to that he had approximately 16 years of insurance and reinsurance underwriting experience.
Hollyman takes over the helm of Gallagher Re Australia and New Zealand from Heather Bone, who left the brokerage late last year and has been regional chief executive since May 2022.
