'No Vision' For Resuming International Travel, Aussie CMO Says

Australia's Chief Medical Officer has provided a grim prediction for international travel, claiming he cannot see a point in time Australians will be able to travel abroad again.

Professor Brendan Murphy told a Senate inquiry on Wednesday there is “no clear road map” out of the international lockdown.

“I cannot see border measures (being lifted), they will be one of the last things to go,” Professor Murphy said.

“Two-thirds of our cases have been overseas-acquired and recent analysis in academic literature has shown that those countries that have done the best have introduced border measures,” he added.

Having to reapply coronavirus lockdowns due to new outbreaks could cost Australia $4 billion a week, treasurer Josh Frydenberg said in a COVID economic statement.

While Deputy Chief Medical Officer Paul Kelly said a commercially available vaccine would be vital if the international travel ban was lifted -- which he expects could be at least a year away.

“A vaccine would be welcome for all sorts of reasons, including an ability to open the borders, and more importantly to bring the pandemic under control,” he said.

"It is important to put this on the table: this virus may become just another endemic virus in our communities, and this virus may never go away," WHO emergencies expert Mike Ryan told an online briefing on Wednesday.

"I think it is important we are realistic and I don't think anyone can predict when this disease will disappear," he added.

"I think there are no promises in this and there are no dates. This disease may settle into a long problem, or it may not be."
