The four-year-old koala, named Blake by the RSPCA, is one of 13 koalas to receive life-saving surgery following road trauma this year.
The koala was hit at Mount Gravatt in Brisbane in March, before being found and brought to wildlife vets with liver lacerations and severe bruising.
“Someone was able to find him, bring him straight into the hospital and we were able to perform life-saving surgery on him,” RSPCA wildlife vet Rebecca Millers said.
“We had to go into his abdominal cavity, clean out the trauma that had happened he has done so well in care.
“He’s been an amazing patient.”
The young koala left his carers today, returning in full health back to the bush.
“We’ve all loved Blake and it was such a privilege today to be able to release him back into the wild,” Ms Millers said.
