On the eve of ANZAC Day, Australian Story revisits the secret weapon behind an audacious and top secret World War II mission – a rickety old fishing boat. The inconspicuous MV Krait ferried 14 commandos thousands of kilometres behind enemy lines into Singapore harbour in 1943. The mission? To blow up enemy shipping right in the heart of Japan’s wartime stronghold. The men involved in this extraordinary raid included some from the top secret, so-called ‘Z Special Unit’. For ‘Z Special’ veteran Douglas Herps, telling the story of MV Krait, and preserving the boat for future generations, became his final mission. The Story of the Krait also features Roma Page, whose husband Bob Page was on board MV Krait. It was only when the secret exploits of ‘Z Special Unit’ were finally revealed many years after the war that she came to understand Bob’s bravery and ultimate fate.
