The fires of war become the forges of Australian invention. William Scurry invented a decoy drip rifle to help Anzacs safely evacuate from Gallipoli. Alexander Worsfold built his all-terrain transporter to hurry injured soldiers to field hospitals on the Western Front. Adelaide-born Howard Florey and his team developed the wonder drug penicillin that was first deployed amongst infected allied soldiers during World War II. And from Wollongong, Evelyn Owen's submachine gun out-performed its competitors and become known as 'the diggers' darling'.
