“Urgency is now a structural feature of our operating environment. It’s not temporary, and it’s not going away.”

We’re joined by Rebecca Humble, CEO of Aurizn, a leading Australian defence and national security company delivering advanced capability across modelling, simulation, and mission support.

With more than 30 years of global experience across Australia, the UK, and the US, Rebecca shares what it takes to lead and scale in one of the most complex and highly regulated sectors.

In this episode, Rebecca shares:

• How the changing global threat environment is reshaping strategy and decision-making
 • Building and retaining talent in a highly constrained, mission-driven sector
 • Executing a buy-and-build strategy to strengthen Australia’s defence capability
 • Navigating the transition from founder-led to CEO-led leadership
 • The role of AI in defence and why trust and regulation matter
 • Leading with integrity, transparency, courage, and a “pay it forward” mindset
