I'm applying for the commercial program and I had my Stage 2 testing last week. I was told that I'd hear back from Qantas within a week or so, but I think the 'or so' might be operative! I also had the same experience as tcross in relation to the Skills Test.
Qf86, I think it might be worth calling them/emailing them about your application. Even if you submitted it at the 11th hour, it's been a long time. I also think - and this is only a hunch - that they'd be keen to get the Level 1 cadets organised first... because of the administrative requirements associated with doing a uni degree.
