Hey Grug - what an admirable ambition.
Did you know you don't have to go to university to become a nurse? You can go to TAFE and do a 2 year 'Diploma of Nursing' to become a Division 2 Nurse.
See this site and select which state you're from to find out further information.

And don't worry about not having Year 12. You can always apply as a 'mature age' student. Not sure exactly what the specific of 'mature age' are - it could be as young as 19 or a one year out of high school. Check with your local TAFE.
Another option would be to consider doing a Certificate III in Personal Care (or Aged Care) to get a foot in the door. This is just one semester full-time and earns you the basic qualification to work as a Personal Care Attendent (PCA), say in a Nursing Home or Hostel. You would then probably be able to articulate into the Nursing Diploma, and still get work in your area of interest while you continue to study and get exemptions from those subjects you've already studied.
So there's more than one way to reach your goal.
My husband works in a nursing home and loves it. You'll find that the people attracted to this care industry have the kindest hearts and are just the loveliest people, so he gets on well with everyone. I bet you must have a big heart, too.
I personally love study. I have spent almost 10 years during my 'adult life' studying one course or another. I don't do it for the qualifications, I do it because I love to keep my brain active and I find that it opens many doors.
Just keep moving! And don't be lazy...
