What do you mean by location clause exactly?
Your RSA should be ok. I know the QLD ones expire and VIC ones are forever( I think) but not 100% about the NSW. Just call the company you did yours with and ask.
I didn't have my CPR or first aid on my AD and I still got in.
Try not to stress yourself out too much, be yourself and try to enjoy the day. I never thought I had a chance when I went to mine so I breezed through. But now when I go for internal interviews for stuff im a nervous wreck and don't think I go so well (lucky they know me enough to realize I'm just nervous)
Also small note, I spoke to a few of the cabin crew that did the last SYD AD and they were amazed by the talent. Apparently they only turned away 2-4 people and that was mainly because they didn't have essential stuff (eg. A drivers license)
