"Australia has reopened its international border for the first time in nearly two years, bringing joyful family reunions and a boost to tourism. The country imposed some of the world's strictest travel bans after shutting itself off in March 2020 due to Covid... More than 50 international flights were due to land on Monday. Travellers can enter all states except Western Australia, which remains closed until 3 March and will require three jabs. "What wonderful, wonderful news for our tourism industry and the 660,000 people employed in it," said Minister for Trade, Tourism and Investment Dan Tehan. Australia had about 9.5 million overseas visitors in 2019. Mr Tehan said he hoped for a strong rebound in the tourism sector, which has been hit by domestic travel bans too... "It is not going to be a magic recovery," said Careem Angel, from Josophan's Fine Chocolates. Rebuilding Australia's multi-billion-dollar travel industry will take time."
