Australia and New Zealand will ban entry to all non-residents from Friday in a bid to limit the spread of coronavirus.
Australian Prime Minister Scott Morrison said his nation's order would come into effect from 21:00 on Friday (10:00 GMT).
New Zealand's will begin earlier - at midnight local time (11.00 GMT Thursday).
The bans do not extend to citizens, permanent residents, or their families.
"We have been thinking to align arrangements across the Tasman Sea," Mr Morrison told reporters on Thursday.
He added that national carrier Qantas would help with getting Australian residents home.
