Nicholas “Nick” O'Sullivan
Townsville IT & cyber security professional
I'm Nicholas O'Sullivan, usually Nick — a Townsville-based IT professional with more than 17 years of experience across infrastructure, cloud platforms, education technology, cyber security, systems administration and practical technology leadership.
I help businesses, schools, charities and community organisations with cyber security reviews, Microsoft 365, networks and technology planning through Suburban Australia and Suburban Secure.
Professional focus
I focus on secure, explainable and maintainable technology: strengthening school technology foundations, improving cloud and identity governance, planning resilient infrastructure and helping organisations understand which technology risks and improvements matter most.
Technology leadership
Strategy, service delivery, infrastructure planning, documentation and practical risk management.
Cyber security
Identity, Microsoft 365, endpoint management, cloud governance and security-minded operations.
Infrastructure
Networks, servers, virtualisation, automation and maintainable systems for complex environments.
Technology in Townsville and regional Queensland
I write from the perspective of someone working in information technology in Townsville: regional cyber security incidents, digital inclusion, education technology, infrastructure and the practical constraints local organisations face. My cyber security research and resources bring together regional guides, North Queensland Cyber Watch and practical writing on governance. The regional incident tracker keeps the sources and the limits of each report in one place.
