Australia had been attacked by air in the north at Darwin. Its pans to defend a line around Brisbane were upset by the daring attack in Sydney Harbour. This attack increased public fears of an amphibious attack on the south, but of course this could not have happened as the Japanese had run out of resources to do any out any substantial invasion. The best they had left for the invasion of New Guinea was a marine regiment in the failed attempt at Milne Bay and a scratch half-division at Kokoda.
Australia's forces were five infantry and three armoured divisions in Australia and three infantry divisions returning from the Middle East. Still, that didn't stop[ a panic over the Sydney event. Our government was not very adept at responding to psychological warfare to put it mildly.
