Don't forget the smaller ones in Oz too, if you don't mind relocating (in the job you'd hope not, eh???)
I just got selected for a job with National Jet and am off from Adelaide to Perth, but Rex are hiring too!
Oh, as for the clothing, even if the email says its a seminar DON'T rock up in shorts and a t-shirt (I was at a "seminar" where someone did this!)
