If you live in the Australian Capital Territory during August you can be on a platypus watch. How exciting. These animals are special, but elusive, so to see one in its natural habitat would be so memorable. There is a good summary of what to know about platypuses here.
There is not an abundance of picture books about the platypus. Unlike echidnas, possums, wombats, kangaroos, bilbies and koalas who feature in stories and expository texts, platypus don't and when they do they are often not written or illustrated by Australians.
Sue Whiting and Mark Jackson's Platypus is the most recent and the best. This book is part of the wonderful Nature Storybook series where there is two fonts, one telling a narrative and the other giving facts about the animal. These other three are older, but they will add to your knowledge and allow the reader to see the platypus as a story character and learn some of the Aboriginal Dreamtime connection it has and they are published in Australia.
