I’m Nicholas O’Sullivan, usually Nick. I was born and raised in Townsville and have spent more than 17 years helping people and organisations make technology work for them.

My experience spans running a local IT support business, supporting Queensland state schools and leading IT in an independent school. I also work with community organisations and take on consulting projects separately from my school employment.

I value a calm, practical approach: understand the problem, explain the options and leave people with systems they can maintain. You can explore my IT consulting services or technical skills and certifications.

Experience snapshot

Education technology

Since October 2024, I have worked as an IT Manager in an independent school. My responsibilities include reliable networks, cloud services, device management, cyber security and planning future improvements.

Before that, I supported regional and North Queensland state schools with technology planning, wireless networks, phones and device management. Working with school staff taught me how much good technology depends on clear advice and a useful handover.

Small business and consulting

I spent seven years operating as a sole trader before moving into education roles. Today, I provide consultancy through Suburban Australia, with specialist security services through Suburban Secure. Townsville Computer Man is the computer repair and support offering.

Community and family

I have served with Northreach Community Care and Northreach Baptist Church in governance and technology roles. My volunteering has also included media and promotions for Stable in Townsville.

In 2026, Sophie, our daughter Madeline and I helped with a family photoshoot for Stable in the City, dressing as Mary and Joseph to promote the Christmas event.

My faith is part of that story. You can read my Christian testimony or visit my personal blog for more about family and everyday life.
