The Seth Effricans wanting to get into Ozmate angle has been discussed here at length some time ago - and apart from them, I think it's safe to assume they'll score a handful of Australian 777-endorsed pilots who will be willing to come home whatever pittance is on offer.
I'd be very interested to hear how the regulating authorities on both sides of the Pacific will react if VOz cranks up an operation with no pilots who have extensive 777 and ETOPS experience.
To repeat my earlier comment: if they stick to the timetable they quoted in their teaser phone-out, I think they'll get an awful lot of "I'd love to attend, but I can't on that day" replies.
