Career
After the war, Wong Sue was a businessman, owning a diving store in the Perth suburb of Midland. He was also an author, a guide for tours of Borneo and a musician, who performed with bands in Perth for about 60 years. On 25 September 1943, Wong Sue joined the Royal Australian Air Force (Royal Australian Air Force).
In 2010, Australian military historian Lynette Silver disputed claims made by Wong Sue in his memoirs and said that official archives prove that he "lied".
In particular, she questioned Wong Sue"s claims that he:
Took part in a raid on the Japanese garrison at Pitas on 13 June 1945, as he is not named in records of the action, and;
Witnessed the last Sandakan Death March as he was in hospital when it occurred and was elsewhere when the other marches took place. In early 2011, Jack Wong Sue"s son, Barry, released a report which he stated refuted the claims made by Silver against his father.
Wong Sue was discharged from the Royal Australian Air Force on 21 January 1946, after which he returned to Perth and subsequently opened a retail store devoted to diving equipment in Midland, the first such store in Western Australia. His published works include two books published circa 2001: a memoir of his military service, Blood on Borneo, and a collection of anecdotes regarding a 1963 shipwreck, Ghost of the Alkimos.
