Speaking of Australia, I was completely obsessed with it as a kid. Part of the reason was because The Rescuers Down Under was my Disney on-repeat of choice, but I also had some books set in the country which fed into my mania. I wish I could remember enough about them to even describe them, but unfortunately I only have vague memories of book covers and mention of wallabies. Possibly there were talking wallabies. These may have come from the Christian book catalogs too, but I don't remember.
