A new campaign has enlisted the help of some of Queensland's most famous faces to spread the message that much of Queensland is back in business following recent natural disasters.

Treasurer and Minister for Employment and Economic Development Andrew Fraser extended the call to all Queenslanders to back-up the campaign by passing on the word via social media.

"While communities were hit hard by the floods and Tropical Cyclone Yasi, many key industries and regions were unaffected or have now fully recovered," Mr Fraser said.

"We have to guard against taking another economic hit by letting the world know our state is open for business."

"Great stretches of Queensland including key tourism areas . . . were not affected and the Port of Brisbane and all our major airports and highways are open.

Mr Fraser said the Premier, Young Australian of the Year Jessica Watson, designers Pamela Easton and Lydia Pearson, the King of Rugby League Wally Lewis and Governor General Quentin Bryce had produced videos messages as the centrepiece of the campaign.

"We have set up a website that will be updated with information about industries and regions that have opened their doors and rolled out the welcome mat to tourists and investors," Mr Fraser said.

"It's now up to us to get online to share photos of your tourist attractions on facebook and tweet updates from your community on twitter - let's tell the world that Queensland is back in business."

Mr Fraser said the 'Back in Business' website linked to information on Queensland holidays, urged people to buy Queensland products and services, highlighted recipes using key Queensland produce such as prawns and avocados and included regional profiles and trade and investment information.
