About Crackerjack

Your IT support and solutions team

How we started

We began small ourselves – as a one-man band in fact, when founder Mark Abraham began helping local businesses in Adelaide with computer support in 1998.  Mark discovered he loved empowering businesses to use technology more effectively to help them grow and turned his passion into a business.

Since then, Mark has amassed an enormous amount of personal experience in helping hundreds of small to medium-size business clients solve their IT problems, both within Adelaide and nationally.  He’s gathered a team of expert consultants and support staff to help him deliver his vision and continue growing a healthy client base.

We’ve built on Mark’s philosophy of fun, friendly, professional and reliable IT support at extremely good value.  We thrive on partnering with individuals and companies who share our same zest for life and work and accept only the best.
