Jetstar are heading into their usual cycle of having too many pilots to not having enough pilots. Melbourne based F/O's are always doing 5 night stays in Newcastle and Cairns to cover the flying. The F/O's going to QF are not being replaced so expect to see cancellations as a regular event. The new rostering system starts in September and is touted as the answer to the problem but it will just create new problems as there is a lot more paxing involved, and we all know how well the airlines can maintain their schedules with ATC and weather delays.
