Could be a chap called Alex Edward Brown, he sometimes does the interviews. Just tell them about yourselves and your experience. that you are aware of all the changes that are going on at Glenside at the minute. The Royal Adelaide whilst comes under CNAHS is actually a different campus. So double check that at interview so you know where you may want to base yourselves.
If you are unsuccessful with the interview which im sure you wont be, then ask them to take you on as a sponsored RN, then you can apply for any other job that comes up. There are lot of prospects and as soon as you are here, even as an RN you can reclass to a level 2 CN. Hope this helps
