Jamie Madden, of Bombah Point Eco Cottages, said he found the adult male kangaroo with a target arrow lodged in its back early on Friday, January 24.

"It was really disturbing to see, especially with it being one of our resident kangaroos," he said.

Mr Madden contacted wildlife carers Wildlife in need of Care (WINC) who were able to find a vet to tranquillise the animal and then remove the arrow.

After receiving some treatment, the eastern grey kangaroo was returned to the wild.

"We believe it should be able to recover," Mr Madden said.

"It's been giving the best fighting chance."

Mr Madden said the arrow was not a hunting arrow but a target arrow, showing it was not a professional hunter who speared the animal.

National Parks and Wildlife Service Great Lakes area manager Stephen Smith said the act of spearing the kangaroo was "cruel" and "mindless".

"It is in breach of the National Parks and Wildlife Act 1974," he said.

"Kangaroos, like all native fauna, are a protected species and harming them carries a maximum penalty of $11,000 and six months imprisonment."

The police have been notified and anyone with any information can call Crimestoppers on 1800 333 000.
