Saw a post on FB on one of the Australian quarantine groups that said something like this, if I may quote:
Im in Hong Kong, but Australian citizens.
Was hoping to travel to Sydney on the 10th with husband, 2.5yo and 4 week old. We have packed up our life here, sold everything and about to ship back what we have left and move out of our apartment.
Due to circumstances outside our control- we have expired Hong Kong visas. The immigration department here and the company my husband works for arent seeing eye to eye (we aren't the only family in this position, but in the mean time also have no access to basic public healthcare because of the expired visas), and they wont be renewed any time soon.
Immigration wont allow us to leave HK on our current expired visas - so we would need to move onto tourist visas to leave. Which means my husband can no longer receive a salary.
Im considering just rolling the kids and I onto the tourist visas so I can leave with them alone, and husband stay wait out a visa resolution here.
Don't know for sure which company she talks about but CX would be a good guess.
