Koala survives being hit by car and trapped in grille for kilometres

Bear Grylls is one of the world's most famous survivalists and a plucky marsupial who survived a major ordeal has been named after him.

He became caught in the grille of a car in Logan, south of Brisbane, at the end of May.

"Sadly he was caught in the grille of a car," Vet Dr Stephanie Shaw said

The four-year-old is faring better than expected. Despite travelling about 30 kilometres, he only suffered a broken leg.

"Bear Grylls is definitely a fighter and a survivor. Logan City Council senior environment officer Samantha Colbran said.

"He was hit in Logan on Mundolin Road but travelled up to Tambourine Mountain, so quite a distance for him to be holding on for life."

He had surgery the next day.

"He's got a plate, and quite a few screws in his leg," Shaw said.

He'll remain at the Moggill Koala Rehabilitation Centre for the final stages of his care until he's released, hopefully in the coming weeks.

With koala breeding season now in full swing, it's a timely reminder the cuddly creatures are on the move.

"One of the major things people can do to help koalas is to slow down on our roads, especially where you see roadside vegetation and koala warning signs," Colbran said.

Logan City Council is launching its annual awareness campaign including installing more flashing road signs.
