The 32-year-old nanny from Palo Alto, Calif., spent three days researching and talking to Australian friends before she decided to book her trip to the island continent, which for two years had some of the world's strictest border controls and longest lockdowns aimed at controlling the spread of the coronavirus.

"They all said, 'if we go back into a lockdown now, people will go into the streets,'" she said. Her two-week trip is scheduled to start a few days after the border opens on Feb. 21.

Potential travelers and tourism operators alike are cautiously optimistic about "Fortress Australia's" reopening, but many wonder if the isolated nation's ongoing Covid restrictions — such as vaccine and testing requirements, as well as mask mandates — will make the return of international travel more of a trickle than a splash. Australia's reputation for rigidity and reclusiveness during the pandemic — at odds with the inviting, easygoing nature portrayed by the country's tourism boards — may also be a hurdle to overcome.

"There is no doubt that a full recovery will take time, but we are confident that the demand for Australia is strong," said Phillipa Harrison, the managing director of Tourism Australia, the country's tourism board.

Tourism was one of the fastest growing sectors in Australia's economy before the pandemic, contributing 45 billion Australian dollars in 2019, or $32 billion.

Australia is among the world's most immunized countries for Covid-19, with 94 percent of people over 16 fully vaccinated. Through 2020 and 2021, the country pursued a tough "zero Covid" strategy that closed national and state borders; restricted Australians from returning home and even leaving; enforced monthslong lockdowns and required its few visitors to undergo expensive hotel quarantines. Surging cases of the Omicron variant of the coronavirus in January, which persist, but have since declined, tipped most of the country into a new 'living with the virus' phase.
