I have also received emails of Koalas plonking themselves in front of sprinklers to cool down. One had his face right on the sprinkler. Unfortunately I can't show those photos because they wouldn't save.
The below is Sam the Koala that the volunteers found in the fires.
Almost looks like he is savouring it as if to remember the tasteThis little guy is obviously enjoying the cooling off but would love as much in his mouth as possible.
Koalas are not known for drenching themselves either but in this heat, who cares about the wet hair look.
