Opposition Leader Peter Dutton says Australia must end mandates requiring passengers on international flights to wear masks when flying into the country.
It follows Qantas lifting its requirement for passengers to wear masks on outbound international routes when the destination country does not require them.
That means those catching flights to the United States, United Kingdom and some parts of Europe no longer need to wear masks.
Current government regulations say passengers on all inbound international flights must wear masks, along with those on all domestic flights.
Mr Dutton told Sydney radio 2GB the mandate "doesn't pass the pub test".
"We've taken a decision to take the health advice, that's always prudent. But if you've got a situation where on one leg of the flight you've got to wear a mask, but not the other, that just doesn't make sense," he said.
Mr Dutton agreed with an assertion the mandate was a "handbrake" on the economy, with people potentially avoiding flying to Australia if they must wear a mask on the flight.
"People have a choice. If you want to wear a mask, if you want to have your kids wearing a mask as well, that's a decision for you ... but I don't support a mandating of it," he said.
