There have been many stories about Japanese landings on Australian soil during WW2. The majority of these stories are unsubstantiated and more than likely not true. Of the following stories on this page, there are only two that are substantiated by official documents.

The first one involves a Japanese Army Reconnaissance party landing on the Western Australian coast near Cartier and Browse Islands. While on Australian soil the Japanese even took some 8 mm movie footage of what they saw. As it turned out they had landed only 25 kms from where the RAAF were several weeks later to start building their secret airfield at Truscott.

The other incident has become known as the "Kentish Affair". While it was not a case of Japanese landing on Australian soil, it is about a Japanese floatplane landing in Australian waters off the Northern Territory coast and taking an Australian clergyman as a prisoner.

Did the Japanese ever plan to invade Australia? There have been no substantiated approved Japanese plans to invade Australia unearthed at this stage, though there was at least one Japanese invasion plan proposed which was knocked back by Japanese Prime Minister, General Tojo.
