THE discovery of two dead dingo pups, believed to have been run over in the car park at Lake McKenzie on Fraser Island, has devastated the Hervey Bay couple who found them.
Steve and Robyn, who asked for their surname to be withheld, were visiting the island on Friday when they found the pups dead in the car park near the lake.
Robyn said the car park was full when they had arrived and found the pups dead.
Her husband Steve went to the toilet facilities near the lake and alerted the rangers there about what they had found.
Steve said he was frustrated by the reaction of the rangers.
"They didn't seem worried about it," he said.
He said the rangers had continued cleaning the facilities before coming over to view the scene.
While it was possible both pups had been run over, Robyn said their bodies were about 50m apart and it seemed strange that both had been hit by cars.
Fraser Coast area manager Ross Belcher said the Queensland Parks and Wildlife Service was investigating the deaths of the two dingoes.
He said the dingoes were born last year and were about six months old when they died.
"Necropsies will be carried out to determine the cause of death, but vehicle strike cannot be ruled out," he said.
"It is very important for motorists on Fraser Island to take extra care to avoid wildlife."
Mr Belcher said tough penalties were in place for those who deliberately killed or injured dingoes, as they were protected wildlife in national parks.
