Upon looking up these courses, it seems most of them are offering Microsoft or Linux certifications. Most of which can be done at TAFE, or the books purchased and the test done at an independant testing centre, for barely a quarter of the price of what you'll be paying.
MCSA, MCP, Cisco, RHCE etc etc can all be attained at various TAFE's around the country. All these qualifications are internationally recognised, and where you get them is irrelevant. The Express IT course may be worth it, but I'd certainly look into what other options are out there, everything they offer can be attained for much cheaper. It just depends on whether you're happy doing a few courses over a year, instead of doing it in 3-4 months that they offer. Or if you're a keen learner, do it at home.
