Vaccinated Australians have been free to travel the world through east coast airports in coronavirus-affected Sydney and Melbourne since Monday when a 20-month-old international travel ban was lifted. Western Australia is the only Australian state or territory that does not intend to reopen this year. It also has the nation’s lowest vaccination rates, in part because the state has had few infections and life has been relatively normal throughout the pandemic. Western Australia is the largest state, covering a third of Australia’s land area. CANBERRA, Australia (AP) - While people are now able to travel freely in Australia’s more populated east, COVID-19-free Western Australia will maintain its tight restrictions into next year, state leaders said Friday.
