I'm sure they would, but they don't currently have the quarantine capacity to accept all of their own citizens that want to return, so there would be public outrage if the capacity were used for tourists, no matter how profitable. Many Australians (including loved ones of mine) are currently stuck overseas with flights repeatedly being cancelled. It's really shameful the country isn't doing more for its own citizens.
