Both Geraldine and Kate are thinking about the sea today. Kate's happy pants are white, like the sail of a boat flapping in the wind; Geraldine's are a deep cool blue, like waves splashing on the rocks. They've got a compass, a very large paper map, and a taste for adventure. Join them on a journey of discovery as they find out about the history of Australia, listen to some songs and special guest Maddie reads this week's story.
