What does the Australian country town of Gundagai make you think of? The statue of the "dog on the tuckerbox"? The old folksong, Along the road to Gundagai? Or do you think of the great flood of 1852 – the deadliest in our history - and the remarkable heroism of two Aboriginal men who saved over 60 people, using their bark canoes. Writer, Anita Heiss, a Wiradjuri woman, talks to Paul Barclay about her new book, Bila Yarrudhanggalangdhuray, which celebrates unsung Aboriginal heroes, and the Wiradjuri language.
