With the number of announcements from QF about restarting operations which then were subsequently cancelled, most people would be a bit wary of making a booking for a long haul trip. Two weeks in Europe is a bit different to a weekend in Cairns if the wheels come off.
No doubt bookings will surge once the first group of arrivals is shown hugging their relatives outside the customs area. Matching supply and demand will be an issue as the recovery gathers momentum, but no doubt QF are carefully planning for a few different scenarios and getting aircraft and crews ready.
Even with access to staff travel, I wont be joining the first waves of travelers. I'll wait for things to settle down a bit first and make sure the borders actually stay open. After a year and a half, waiting a few more months while the situation stabilizes won't hurt.
