A koala with seven gun pellets lodged in its body will undergo surgery at Australia Zoo today.

The six-year-old koala was found on a Kippa-Ring property by Department of Environment and Resource Management officers yesterday, according to The Courier Mail.

A vet who examined the koala, now known as Fleet, said she was disgusted by the extent of the animals injuries and the cruelty involved in the case.

"Every limb has been shot," Dr Amber Gillett told The Courier Mail. "He's been shot from every side.

"It's just an immense cruelty to picture someone standing there taking pot-shots as this animal as he tries to move away from them - it's just horrible.

"Fleet will require intensive monitoring and care over the coming days. My biggest concern for Fleet at the moment is the spread of infection; he is suffering from sever infection in his back leg which is associated with a pellet wound," Dr Amber said.

The koala had been placed on intravenous antibiotics, strong pain relief and fluids and is currently at Australia Zoo Wildlife Hospital on the Sunshine Coast.

Spokesman Brian Coulter told ABC the koala may have been shot up to a week ago.

"The vets need to stabilise the koala before it can go in for operations to have the pellets removed,' Mr Coulter said.

"The other thing that we've got to worry about is that one of the pellets is lodged in its skull."

Senior Sergeant Pat Howard, told the ABC police would work with RSPCA officers to try to find the culprit.

"Police take this type of offence quite seriously so we're asking anyone with any sort of information to come forward," he said.

"We want to ensure the matter is investigated thoroughly."
