In November 1993, during a holiday in northern Queensland, the author met a man who witnessed a Thylacine (Tasmanian Tiger) on Cape York Peninsular. This prompted the author to try to confirm that they still live. On hearing from Mr Heath of some of the Thylacine sightings he had been told about, an academic at a Queensland University urged him to write this book. "Thylacine: Confirming Tasmanian Tigers Still Live" details some of the many Thylacine sightings on mainland Australia and Tasmania that the author has been told about up until 2014.
