Australia is already in talks to establish a two-way travel bubble with other countries as quarantine-free travel to New Zealand kicks off from Monday.
The much-anticipated trans-Tasman bubble between Australia and New Zealand is now under way, with the first plane load of Qantas passengers from Sydney arriving in Auckland on Monday afternoon.
But Transport Minister Michael McCormack said officials had also begun talks with other nations in the Asia-Pacific region.
"Hopefully, more travel bubbles will be able to be opened up with perhaps Singapore … Japan, South Korea, South Pacific Island nations," McCormack told Sky News.
Asked who was at the top of the queue, McCormack said: "Singapore."
"We started those discussions some weeks ago between the departments of the transport ministries of both countries," he said.
"As the vaccine rolls out here and elsewhere, it is important to know that we have the confidence for people to be able to travel … and not to have to go through the quarantine situation."
McCormack said the two-way travel bubble between Australia and New Zealand had occurred because both countries had handled the Covid-19 pandemic well.
"(Those) governments have kept their people safe, and that's why we're able to open up this travel bubble," he said.
However, he said future travel bubbles would depend on medical advice.
