Qantas Airways Ltd and Tourism Australia announced a new three-year partnership worth $44 million to market Australia internationally as a tourist destination.

The Memorandum of Agreement (MOU) covers activity over the next three years including international cooperative marketing campaigns, major trade events, business events and public relations activities across Europe, Asia, US and New Zealand.

Qantas Group executive commercial Rob Gurney said the partnership would deliver significant benefits for Australia's tourism sector.

"We look forward to working with Tourism Australia on this cooperative activity to strengthen Australia's position as a desired tourism destination and covert that desire into visitation," Said Gurney. Tourism Australia managing director Andrew McEvoy said the launching recognised the importance of the Tourism Australia- Qantas partnership to Australia's tourism marketing effort.

Qantas chief executive Alan Joyce, who was present during the launch of the partnership at the Australian Tourism Exchanges (ATE) in Adelaide, said that the airline group is performing well in a difficult environment.

Joyce said Qantas' diverse portfolio provided stability of earnings compared to other airlines.

"We have the unique ability to be able to grow whichever brand is performing best at that particular time," said Joyce.

The Qantas group comprises full-service carrier Qantas and low-cost offshoot Jetstar.

On Friday, Qantas said its full-year earnings guidance remained unchanged, with underlying profit before tax expected to come between $300 million and $400 million.
