I would disagree with 90% of what Pferdenuts said. Not sure how your ranting "again" when it is your first post?
Most regional hospitals are employing BMIDs, they have to as there are few RN/Ms coming through now. tertiary hospitals take anyone and Midwives(only) do look after women as we are able to care for all degrees of women. I know in my BMID i did a hell of a lot (way more then we should) with sick babes. AND there is a very large proportion focusing on the common issues women have nowadays and how that effects pregnancy as we are educated in how to educate them about improving their life and the future for their babies.
The Focus on Midwifery is that it is for normal women and pregnancies and when it moves out of our scope we refer the woman to a suitable model (ideally with us still involved)
A registered nurse has less requirements then a BMID to complete for registration.

In adelaide you have the choice of 2 universities Flinders and UniSA if your not a science head try for UniSA as flinders is definitely a more science based course. UniSa you can get in via a few ways Stat test, previous degree, highschool grades, or foundation studies (course designed for those who have not studied in a LONG time and never at a tertiary level.)
if the current law that is trying to get through gets through there is no point in becoming a doula as midwifery will be a protected profession which means that doulas may find they have a hard time getting work as it does cross some of the midwifery barriers.

I chose not to do nursing as i can not stand dealing with old people.. my focus has always been on women centered care (yes i can do that with a gynea patient) and evidence based practice. and Old man balls freak me OUT!!
