International flights could soon resume out of Canberra, with talks under way on re-establishing direct flights to New Zealand.
Canberra Airport has said it is in discussions with several airlines on setting up routes across the ditch from the capital to either Auckland or Wellington.
The airport's head of aviation Michael Thomson said the resumption of flights to New Zealand could lead to more destinations opening up.
"If things continue, the opportunity for two-way traffic without quarantine provides stimulus for further opportunities as well," Mr Thomson said.
"Once the borders opens up to all of New Zealand, depending on the carrier, it also opens up to connections to North America."
Singapore Airlines previously operated services between Canberra and Wellington, but the route was scrapped in 2018, a little more than a year after it launched.
Mr Thomson said under the right aircraft size, routes to New Zealand from Canberra would operate well.
The first flights from New Zealand to Australia as part of a one-way travel bubble landed in Sydney last week.
While New Zealanders can come to Australia without the need for quarantine, Australians will still need to quarantine for two weeks should they decided to go across the Tasman.
It comes as Canberra Airport announced on Tuesday it would be adding more domestic routes to its schedules.
Direct flights between Canberra and Newcastle on Link Airways will take off from November 20 with four return flights a week between the two cities planned.
The service could expand to as much as 11 return flights a week from next year.
Services to the Sunshine Coast and Cairns on Alliance Airlines will launch on Friday while flights to Port Macquarie and Hobart are slated in coming weeks.
"We're still a long way down from where we were last year, but things are going in the right direction," Mr Thomas said.
"Borders and cities are reopening and that's really important because traditionally we're a business airport and people are getting back to the office."
Earlier this year, the airport was operating at 5 per cent of its pre-COVID levels.
The resumption of new flights in recent weeks has seen those levels increase to a 20 per cent capacity.
Mr Thomson said there had also been an increasing number of passengers flying to holiday destinations such Queensland and Byron Bay.
"There is an appetite there, and once Virgin works through how it will be structured, we'll see them put on more flights and Qantas is starting to ramp up as well," he said.
