I would be happy to travel if only I could but not if it means jumping the queue and depriving a family wanting to return. I'm hoping there maybe a middle ground where vaccinated travellers can enter more easily and quarantine at home until a test result is negative.
It all depends where you are returning from, which underlines what a mess this whole thing is.
This week I can see about 12 seats in PER and at least 27 seats in MEL from SIN on Scoot!.
But some of these are short notice now ... and also you are apparently required to submit an online "Australian Travel Declaration" at least 72 hours prior to departure, so if something comes available with short notice (but still long enough to get a test), it would seem patently ridiculous to not allow people who want to travel to do so based on some bureaucratic nonsense when supply of seats is so limited (by way of contrast when traveling into Singapore, you are required to complete an online declaration no more than 72 hours prior to departure).
