Would you get into the Cert IV nursing? That might be the easier way to go about it, unless you would like to get your VCE. You could apply at all the unis you want to go to but I am not sure how much success you will have, considering you don't have your VCE. It really depends on their entry requirements. I think if you want to go straight to uni, then you will be better off getting your VCE but if you can get into the cert course you can be studying nursing straight away.
