Townsville Computer Man was founded in 2008 by Nicholas O'Sullivan, going public with the brand in 2009. Between then and 2016, it provided hands-on computer repair and IT support across Townsville — residential customers, small businesses, and network and support work for larger operations, including multinational mining companies based in the region.

In 2016, general servicing paused while Nicholas moved into a full-time IT career, though a small number of long-standing clients continued to be quietly supported in the background. That career has since included IT leadership roles across schools and government, and Nicholas currently works as IT Manager at a Townsville school, alongside governance roles in local community organisations.

Townsville Computer Man is now relaunching as a brand of Suburban Australia, the same business behind Suburban Secure's cyber security and technology advisory work. Same ABN, same person, same practical approach — just back doing hands-on repair work in Townsville again.
