well... what type of support role are you looking at? The normal entry level into IT (the one i took) is ISP Help Desk.
Before i did that i was a panel beater and then a warehouse admin person.
Did that for 3 years before moving into the role im in now which i have been in for 4 years now.
All of my mates used ISP help desk as a stepping stone. One is the Manager of the ISP Help Desk, the other is a Trainer, one is a network engineer and one is a CISCO engineer.
Most ISP help desk jobs dont really require any experience because they train you on the job.
