Thanks for your help The Kelpie. What you said makes sense, I am hoping what happened with the other crew member was a bit of a fluke. I will be calling the Consulate today for advice.
And training wheels, the reason I need a tourist visa is because I will be entering Australia on my own time and money, not as a member of a flight crew, so its the
initial entry into Oz that I now need a visa for. In order to use my crew visa I have to be on 'duty travel', which this certainly isn't.
