A koala ambulance service has spent the festive season under attack, with the truck trashed by thieves and teenagers and the drivers copping abuse while trying to save the marsupials.

Sunshine Coast Koala Wildlife Rescue Service founders Ray and Murray Chambers are fed up with the abuse, saying people need to show some respect.

Ray said they had spent the past couple of weeks dealing with attacks on themselves and the koala ambulance.

The first attack occurred when the ambulance was parked at Moffat Beach on the Sunshine Coast and teenagers began kicking the doors of the truck while Ray was still inside it.

This was followed by a theft, with almost $400 worth of cash, donated fuel vouchers and equipment stolen.
