I spent many happy days in the early 1980's with my nose in one of Mary Grant Bruce's Billabong Books, I had the full series and would read them over and over. Unfortunately I lost them all when our house was flooded three years ago however, my daughter recently brought me five of the books to start me on the road to having the full series again, as she knows how much I love them. Needless to say I have spent an enjoyable evening reading some of the articles and excerpts on Trove regarding Mary Grant Bruce and her books.
