Adelaide Hills' bushfire-ravaged koalas cared for at makeshift shelter

In a school hall north of Adelaide, some of the most vulnerable victims of South Australia's bushfire crisis are being treated at a makeshift hospital.

A tent city has been set-up to accommodate more than 100 koalas found burnt, dehydrated and displaced in the aftermath of last month's Adelaide Hills fire.

An around-the-clock team of more than 150 volunteers, including at least 80 trained veterinary staff, moves tent to tent tending to weary patients.

There's an intensive care unit and a burns unit, a treatment area, a chlamydia section, a baby section and indoor and outdoor trees for those ready to climb.

Each koala is named, has a medical record and, when the team is satisfied it has sufficiently recovered, will be released back into the wild.

Population decimated

On Kangaroo Island, as many as 25,000 of the native animals are feared dead in the blazes that ripped through the tourist spot, with many more burnt or injured.

But, despite the devastation, Good Samaritans are stepping in.
