Mark was born in Townsville, North Queensland Australia and is one of nine children for Marcia and John Deguara. The endless year long summers of the north and being part of a large family, made for the perfect environment to have many a great childhood adventure. He remembers his childhood being very much like a Mark Twain adventure story. There was a constant thirst for fun and not having things like computers and other different technology of today, the only way of finding it was to go looking for it and having a huge imagination helped a lot, along with the wide open bush land around my parents home. That laid the perfect grounds for him to become a writer. He is married to Mellisa and has two children, Hope and Nathaniel.
