Aon plc has appointed Quinton Kotze (pictured) as head of cyber solutions for its Australian operations, the global professional services firm announced Monday.
Kotze, who will be based in Sydney, will lead Aon’s cyber solutions capability in Australia and report to Alistair Clarke, head of specialty, Australia. According to a news release, Kotze’s role will focus on shaping the firm’s cyber risk strategy in line with its global cyber practice, bringing together cyber risk advisory and insurance broking capabilities for clients across financial services, global corporate, and national segments.
Clarke said the appointment reflected the firm’s ongoing investment in its cyber capabilities across the country.
“Cyber risk is a critical area of focus for our clients, and this appointment reflects our continued investment in strengthening our cyber capabilities in Australia,” Clarke said. “Quinton brings deep market experience, strong insurer and client relationships, and a balanced, practical approach to cyber risk. He is well placed to lead our cyber solutions business and support clients as their risk environments continue to evolve.”
Kotze joins Aon from Chubb, where he most recently served as digital domain lead and financial lines product manager for Asia. He has held senior cyber and financial lines leadership roles across Australia and the broader region and brings more than 19 years of experience in the financial lines sector, including earlier roles at AIG and Marsh.
“I’m delighted to be joining Aon at a time when cyber risk is firmly on the agenda for organisations across Australia,” Kotze said. “Aon’s integrated approach, combining advisory, data, analytics, and insurance, provides a strong platform to help clients make better decisions. I’m looking forward to working with colleagues across the firm to further build sustainable, client-focused cyber solutions.”
The appointment comes against a backdrop of growing cyber threats across Australia. The Australian Signals Directorate (ASD) responded to 138 ransomware incidents in the 2024–25 financial year, while distributed denial-of-service (DDoS) attacks rose more than 280% year on year, according to its Annual Cyber Threat Report 2024–25. Separately, research firm Cyble documented 71 major cyber incidents targeting Australian organisations in the first half of 2025 alone, up 13% on the same period in 2024, spanning sectors including financial services, healthcare, energy, and telecommunications.
The cyber insurance market has responded accordingly, with Australian organisations increasingly seeking protection against ransomware, phishing, and emerging AI-enabled threats. The ASD reported that self-reported cybercrime costs for medium-sized businesses rose 55% year on year in 2024-25, with average incident costs approaching $100,000.
