Queensland police have appealed for public assistance to help find offenders who shot and decapitated a pet camel.

Officer-in-charge at Birdsville police, Neale McShane, says they are investigating the death of 'Noodles' the camel on a cattle station outside of the town in far south-west Queensland in late September.

He says Noodles was being rested, during a planned walk from the Kimberleys in Western Australia to Charleville.

"Noodles was at Durrie Station, which is about 100 kilometres east of Birdsville, in a paddock about 150 metres off the road," he said.

He says the camel was quiet and would have approached the offender.

"This is just a blatant shooting of a domesticated camel," he said.

"It appears he was shot at point blank range, and unfortunately then the person cut his head off.

"Noodles was at the Birdsville Races - he probably had his photo taken by about 3,000 visitors to the races.

"People talk, and put two and two together, and hopefully this crime can be solved.

"We are hoping that someone may have been bragging about it, or telling someone about it, we'd like to either contact Birdsville police or Crimestoppers."

The camel's owner, Shawn McCulloch, says it is difficult to understand why anyone would kill the animal.

"He was my best mate - we had some great times, he made me laugh, he would sit down next to my tent, so he was well-loved and well-cared for," he said.

"I made sure he had the best of grains and the best of hay, and the best of lucerne.

"We don't know - we probably will never ever know why they decided to cut his head off or shoot him, we don't know why - it just doesn't make sense."
