Try this link, it has a flow chart to show what qualifications are needed.
I'm currently studying the enrolled nurse diploma and want to go on to do the degree and eventually follow this path too, I have a 2.5 yr old, and a 10 month old, it's hard work, and it's only 3 days at tafe so far. Fitting study in when you get home with kids requires a partner who is understanding and will get the kids out from under your books for a few hours a day.
Good luck X
