In World War II, there were 1,993 enemy attacks around Australia. Scores of submarine and ship fights, and many hundreds of individual enemy air actions, from Darwin to Hobart, from Townsville to Melbourne, which saw thousands of lives lost. Yet Aussies know little of it.

Two new works, from one of Australia’s foremost military historians, for the first time brings together all of the actions in World War II around the country’s coastline – and reveals an 86-man Japanese submarine sunk off Sydney.

The Secret Submarine and Australia’s Coastal War, both detailed in this 60-minute talk, will perhaps surprise you but certainly inform you. From mines on South Australia’s coast, to the sinking of HMAS Sydney, to air raids across the Top End for two years, to submarines fought and sometimes forgotten, this talk touches on them all.

Dr Tom Lewis, who received his Order of Australia Medal for service to naval history, will also take questions from the audience after his photo-packed presentation.
