Computer One inspire a relationship built on trust.  They have served us for 8 years and we trust their staff, their integrity and their technical knowledge.  They support our critical business systems and play an important role in shaping our competitive advantage.  Their expertise is something I don’t think we would get if we hired 2 or 3 people directly.  I'm pleased to recommend them.

We are the kind of company that simply cannot afford to have our computers down; so we are prepared to pay for top class service, and that’s exactly what we get from Computer One. Whenever I have the slightest problem I make a call and they fix the issue fast.

We deliver with speed

One of our most recent projects was to create an accelerated and high performing Wide Area Network, capable of delivering voice and data over a combination of ADSL, Satellite and Cellular networks at remote locations around the country.

From the briefing in Brisbane to powering up the completed network on-site took just 14 days and it was a seamless experience.  Our client came to us with a requirement, and we matched the technology and implemented a solution.

They said their previous IT consultancy, a globally-recognised Tier One provider, couldn’t even have completed its quote in that time.  Now we provide a Managed IT Service to ensure that their ongoing IT requirements are catered for, without interruption.

We have the same skill sets and the same vendor relationships as a Tier One IT Consulting Company.

The difference with us is that you will engage directly with the person who can actually solve your problem.

We’ll get the job done, faster and more cost-efficiently.

Wide-Ranging Experience


We’ve tackled just about every challenge related to IT and delivered successfully. You will find some case studies in our Industry Expertise section.
