Lightning strikes have started fires right across Queensland's west since September and in the far-west large swathes of grazing country have been burnt out; including 800,000 hectares (80 per cent) of the Simpson Desert National Park.

Christine Crafter is the operations manager for the rangelands in the Queensland Parks and Wildlife Service and she said that about 80 per cent of the park has been burnt at this stage.

"The current fire that we've been monitoring is around about two million hectares within Queensland and 800,000 hectares of that is within the National Park itself.

"Other areas around the park that have been affected are the stations such as Ethabuka, Carlo, Sandringham, Adria Downs and Kameron Downs," she explained.

The Parks and Wildlife Service have been working with landholders to protect grazing land around the park.

"Within the park it is a natural process and it is also very inaccessible country and we are limited about what we can actually do within a lot of that country.

"So in some cases we just let it continue to do its own thing until its gets to somewhere where we do have the opportunity to control it.

She explained at times the fire fronts have been big.

"Some of the fronts have been up to 100 kilometres wide as they move through the desert."

Ms Crafter said they've had to close the Simpson Desert National Park a number of times because of the fires.

"Fire can move a lot quicker than people can through the desert, but there's been very little actual danger, so we've been fortunate there.

"Most of the problem has been the threat to loss of production and grazing country around the park and other cattle stations."

Ms Crafter said while the fires currently are not posing a danger; dry lightning storms are still a worry and travellers are being urged to check with authorities before heading into the desert.
