John Ellis

John Ellis is the CISO at Australian Unity, where he focuses on helping organisations translate cyber security from operational activity into clearer executive and board-level decisions. His work sits at the intersection of cyber security, geopolitics, and business value, with a particular interest in how geopolitical disruption, systemic risk, and concentration risk flow through technology, critical supply chains, and organisational decision-making.

John has held senior roles across banking, insurance, healthcare, and technology, including positions at QBE, Bupa, Standard Chartered, Barclays, and Akamai, and has worked across Asia-Pacific and global markets in complex, highly regulated environments. He holds a Master of Cyber Security, Strategy and Diplomacy from UNSW and advocates a risk-led, intelligence-informed approach to cyber resilience.​​​​​​​​​​​​​​​​
