Haha, I can't disagree when I'm wanting to come back for Xmas!
But you know what, Australians overseas are over-entitled w#@ers who don't deserve to come home if they didn't come home by March. (Well that seems to be an underlying sentiment, not stoked, but not exactly dispelled by the media
). Means that there's no political imperative to do so, even though the situation of many overseas is complicated and their means are limited, especially in the face of the significant economic shock (and many job losses) caused by COVID globally.
In any event, an advanced, wealthy country like Australia should be able to find a mechanism to allow both returning citizens and income generating foreign students to safely come back to Australia.
