@pmac I don’t know anyone who studied there but it’s still Australia anyway and do you have much of a choice? It’s either you grab the chance to be enrolled now or be affected by the upcoming change. Ask yourself what’s your primary purpose and where should your focus be. Is it to be in a bustling environment or be enrolled? Just being upfront.
Here’s some info about UniSA.

By the way, we used AECC Melbourne twice before and they’re pretty good. I’m sure their Ph branch is as competent.
