Of the 22 awards, 14 were direct awards and eight were Empire Gallantry Medal (two) and Albert Medal (six) exchange awards. Four awards were to officers of the Royal Australian Naval Volunteer Reserve who served in the extremely dangerous role of mine disposal during the Second World War. Privates Benjamin Gower Hardy and Ralph Jones were posthumously awarded the George Cross for manning a Vickers machine gun during the Cowra breakout, a mass escape by Japanese prisoners of war in central New South Wales on 5 August 1944. Hardy and Jones disabled the weapon and denied its use to the escaping prisoners before they were overwhelmed and killed by the escapees. Courage of a different sort was displayed by two prisoners of war who endured terrible suffering. Captain Lionel Colin Matthews was eventually executed by his captors for building a resistance network in British North Borneo in the Second World War, while Private Horace William Madden, captured in Korea in 1951, died of privations while assisting fellow prisoners and openly resisting enemy efforts to force him to collaborate. The last Australian to be awarded the GC (in 1978) was Constable Michael Kenneth Pratt of the Victoria Police, Melbourne, for arresting two armed bank robbers in June 1976.
