The four-times-a-week service took its maiden flight from Toowoomba yesterday.

Q–connect has added Toowooomba to the Western Two air route operated by Skytrans, to establish a link from Brisbane to Toowoomba, Charleville, Quilpie, Windorah, Birdsville, Bedourie, Boulia and Mount Isa.

State Transport Minister Rachel Nolan said the service would continue on a trial basis until the tenders were called later this year.

"Toowoomba is such a vital hub providing essential services for many western Queensland towns, and this service will be very welcome to those communities and the Toowoomba people who work with them," Ms Nolan said.

"If the trial is successful I am confident it will be continued when the new Q–connect air service contracts are introduced."

The Western Two route, like the existing Skytrans Western One flights, would operate from Toowoomba Airport, not Oakey.

Western Two flights would leave Toowoomba for Mount Isa each Monday and Thursday, while flights to Brisbane would leave Toowoomba each Tuesday and Friday.

"These new services for Toowoomba, and new discounted fares across the Skytrans schedule, are the result of the airline and state and local governments working together to identify service improvements for regional communities," Ms Nolan said.

Charleville Mayor Mark O'Brien said today’s news was welcome and great for the South West.

"People from the South West will particularly be happy because not only do many people from the region have family connections with Toowoomba, but also because South West tends to use Toowoomba as the medical hub," he said.

Barcoo Shire Council Mayor, Bruce Scott, said he expected the new service to be a boon for his community.

"Following the collapse of MacAir there was concern that air services would cease. However, the Queensland Government has proven it is committed to the provision of reliable air services to rural and remote Queensland," Mr Scott said.

All three Q–connect routes operated by Skytrans will benefit from discounted airfares.

The fully flexible fares on the Western One route from Toowoomba to Thargomindah will decrease by 10 percent, down from $406.35 to $367.

Ms Nolan said the emergency contracts are in place and will guarantee the continuity of air services until a full re-tendering of services was completed.
