Whenever I stay at Rottnest I usually see quite a few. We used to stay in a tent at the camping ground and in the evenings the nearby oval and its surrounds would be covered with them. Even during the day there are usually a few semi-tame ones loitering around the settlement area.
What a lot of people don't realise is that they're also found in a few parts of the south-west. When my family and Í have been camping at Windy Harbour (south of Northcliffe) and the Shannon National Park (on the way to Walpole) there are signboards mentioning that there are small colonies living there. However, they're a lot more shy than those on Rottnest Island.
Haha, that's happened to me too, Finy. One time my daughter and I went camping on Rottnest Island and left our tent flap slightly open while we slept. We woke in the middle of the night with a couple of quokkas scuttling around the tent (and on us), looking for things to eat. It was hilarious but a bit frustrating trying to get them out again.
Enjoyed seeing them on Rottnest almost 40 years ago, but don't know how they have fared since. They are cute little creatures and certainly should be protected. I can remember some controversy when one was used as a football by some louts. I think it now has become a standing joke amongst visitors who would not dare put it into practice.
