Portugal and Australia have announced changes to their travel rules after relaxing restrictions.
Australia will open its borders to all vaccinated tourists and business travellers from February 21 in a further relaxation of pandemic restrictions.
Australia imposed some of the world's toughest travel restrictions on its citizens and permanent residents in March 2020 to prevent them from bringing Covid-19 home.

When the border restrictions were relaxed in November in response to an increasing vaccination rate among the Australian population, international students and skilled migrants were prioritised over tourists in being welcomed back to Australia.
The country's prime minister Scott Morrison said his senior ministers agreed on Monday that the border would reopen to all vaccinated visas holders from February 21.
Mr Morrison said visitors must have proof of vaccination. He referred to Serbian tennis star Novak Djokovic being deported by the Australian government last month because he was not vaccinated against coronavirus.
The strictest state border rules are enforced by Western Australia which covers a third of the island continent.
The state allows only 265 international arrivals a week and requires a 14-day quarantine period.
Meanwhile, Portugal will axe travel testing requirements for fully vaccinated UK tourists.
Visitors will now be allowed to enter the country as long as they can show proof of full vaccination.
The date these restrictions will be lifted has yet to be confirmed, but Portugal's current rules expire on February 9.
