It depends on their seniority. Some Captains are off to the A380 a couple to the 744, more to the A330, a handful to the 737 in Adelaide, and the majority are becoming F/Os on the A380 with a couple becoming F/Os on the 744 (their choice rather than the A380).
The F/Os are in similar circumstances. Not sure if any of them are off to the A380 as F/Os though. I don't think any current 767 F/O has seniority for the A380 as an F/O though I could be wrong. A few to the A330 because they have the seniority- some of them to different bases than currently, some to the 737. Majority into the backseat of the A380 with a couple electing to go to the 744 as S/Os instead of the A380.
