I worked with a lovely nurse from Texas when I was student. I know she was from Texas because every single patient we worked with asked where she was from. So expect questions, like "What made you want to move to Australia?", all the time
Nursing is a very high stress job. Studying is a very high stress activity. You will need a lot of drive and good support to be able to do it, but if you can muster that, you can get through it. Good luck
