(CNN) Australian and New Zealand passengers will be evacuated from a stricken Antarctic cruise ship Thursday, after almost 60% of those on board tested positive for the coronavirus.

The cruise operator added it had "formally escalated our request" to the Uruguayan authorities to allow the ship to dock and passengers to disembark, but it had so far been denied.

"We have been working on charters and flights for all onboard with the aim of disembarking our passengers as soon as possible," Aurora said in a statement.
"While our preferred plan had been to disembark all passengers simultaneously, the nature of the situation and the difficultly in securing flights has meant it is likely that ...
