Australia’s Secret Heroes tells the extraordinary story of Z Special unit, a remarkable group of men who were plucked from the Australian military in World War II, trained in explosives, camouflage, silent killing and how to resist torture and then sent on incredibly perilous undercover operations in Asia. For years, the Z Special operatives were sworn to secrecy. But now the veterans relive their incredible wartime exploits. In a unique “living history” approach, Australia’s Secret Heroes takes six descendants of the Z Special operatives and places them on training missions to give them a taste of what their forefathers went through.
