Most people arrive at the CISO chair from the outside. Graham Fairley did the opposite — he earned it from within.

In this episode, host David Savva-Willett sits down with Graham Fairley, Chief Information Security Officer at PEXA (Property Exchange Australia), for a candid and personal conversation. Davey held the CISO role at PEXA before Graham, and the two have been friends and colleagues for the better part of a decade — which makes this a rare, honest look at what it actually takes to grow into one of the most demanding seats in Australian cyber.

Graham progressed through identity and access management, security consulting and a security services lead role before stepping into the CISO chair in late 2024. Eighteen months in, he reflects on the learning curves nobody warns you about: winning executive and board buy-in, sitting with the weight of accountability, learning to let go of the technical work he loves, and becoming the kind of storyteller a modern security leader has to be.

They also get into what PEXA actually protects — a platform underpinning Australia's ~$10 trillion property market and designated critical infrastructure — including the 6.5 million intrusion attempts PEXA blocked in a single financial year, four times the previous year's volume. Graham unpacks PEXA's layered defence approach, and the harder problem beyond the platform: the consumer. As he puts it, criminals don't need to compromise systems — they just need to compromise trust. In this episode:
