Australia, which shut its borders in March of 2020, has been going through a staggered reopening in recent months, allowing in only its citizens and residents, skilled migrants, international students and certain seasonal workers.

His popularity has been sliding in recent months, however, in part reflecting questions about his handling of the Omicron outbreak, and he faces pressure from a federal election that must be called by May.
