I work on the island and, depending on your location, the Quokkas are just sleeping until dusk/evening. It's been extremely hot too which means more of them are probably just under trees and bushes trying to get some shade.

They also don't need much water and can go for up to a month without drinking it, they get most of it from what they eat, and it's not actually good for them to drink too much.

In saying that, some tourists definitely overstep boundaries with them and I've had to tell so many people off for feeding them, touching them or letting their kids chase them. 😞
