Jetstar are currently offering the following for one-way flights on select dates, for travel between April 1 and September 30:

* These prices are subject to change

There are currently a limited number of subsidised flights, particularly from Adelaide to Cairns – with only one depature date in June and four depature dates in September. 

However airlines – mostly Qantas, Virgin and Jetstar – will be releasing new half-price fares each week. 

Travellers can also cash in on half-price flights to Gold Coast, Whitsundays/Mackay, Sunshine Coast, The Lasseter region (Uluru), Alice Springs, Launceston, Devonport, Burnie, Broome, Avalon, Merimbula and Kangaroo Island.

Mark Olsen, CEO of Tourism Tropical North Queensland, said the initiative could drive thousands of extra visitors to the region each week.

"Today’s a step in the right direction for Cairns and the Great Barrier Reef to close the gap left behind without international visitation," he said.  

"If our region can secure our share of this important initiative we can drive another five to seven thousand additional visitors each week. 

"And if they’re new visitors that’s a million dollars a day being injected into our community." 

The half-price flights are being welcomed by the tourism and aviation industry, who are relying on a high visitation over Easter and the school holidays amid Brisbane’s snap three-day lockdown.  

Cairns Airport CEO Richard Barker also welcomed the announcement but said open borders are needed to give people confidence to travel. 

"Anything that stimulates demand and gets people on planes, up to our beautiful region to support the local operators, is welcomed by us," he said.  

"The key thing for us and for this region is that interstate borders remain open."

"We need these borders to stay open so that people from interstate can have confidence that they can book a holiday, get a great deal, have some world-class experiences, and get home comfortably." 

Premier Annastacia Palaszczuk announced this morning the Brisbane lockdown will lift at noon today after just one case of community transmission was recorded.

However for the next two weeks, until midday April 15, all Queenslanders will still be required to carry a mask when outside of their home. 

"We will also ask you to wear those masks in indoor spaces such as shopping centres and supermarkets, indoor workplaces (and) public transport," Ms Palaszczuk said.
