V Australia, when they start up, will most likely operate out of Sydney. It is the largest population base and the biggest market. Thus it would be logical for the crew base for V Australia to be in Sydney.
The airline is apparently starting with 3 aircraft in 2008 and assuming say 14 or so crew on any flight and 6-7 crews per aircraft, thats 3 x 14 x 6 = 252 crew. If these numbers are even close, that's a lot of new cabin crew opportunities for Cabin Crew coming up in 2008 (most likely Sydney).
