If #Australia- #China diplomatic relations were not in the toilet right now the two countries could form a #coronavirus travel bubble given that #Covid is currently pretty much under control in both places. You can imagine including #NewZealand #Taiwan #Vietnam #SouthKorea ?
As part of the travel bubble I imagine you would still require a valid nucleic acid test before boarding the plane and then you could test people again on arrival. Those arriving could remain in quarantine while the test results are coming in.
