There's a greater chance thylacines, known as Tasmanian tigers, could have been saved from extinction if the pleas of renowned naturalist David Fleay had been heard, his son says.
One of Stephen Fleay's earliest memories is of his father's four-month search for a pair of thylacines, starting in November 1945, when Stephen was three years old.
His father had lobbied authorities unsuccessfully to protect the species and was "bitterly disappointed" when he was unable to find a breeding pair, despite evidence the animal still existed.
