A mother koala and her baby have been photographed gratefully accepting water from residents in Adelaide as the state’s heatwave continues.

In a fourth consecutive day of extreme temperatures, humans and animals alike are looking to escape the heat.

The koalas were sitting at the base of a tree yesterday in Dernancourt, Adelaide, when a nearby resident named Mark encountered them.

He found the mother koala sitting in the same spot when he returned a couple of hours later.

“We realised she was crouched with her baby,” Mark’s wife Kathryn told 9News.com.au.

“We brought some water to the parched pair which was much appreciated and the baby promptly climbed onto the mother’s back.”

The two koalas aren’t the first to accept help from humans.
