Best Answer

All other positions of defence between Australia and Japan had already fallen. This included Singapore and the Malay Peninsula. Essentially, Papua New Guinea was seen as the last bastion of defence between Australia and a Japanese invasion. If Japan took control of Port Moresby, in the south, it was regarded that it would be very easy for them to launch both air and sea attacks on Australia.

What was the effect of the invasion of New Guinea on Australia?

The invasion of Papua New Guinea was seen as a very real threat to Australia's security, as defence of PNG and Port Moresby was critical to victory in the south Pacific. Had Port Moresby fallen, it would have left northern Australia more vulnerable to attack. Singapore had already fallen, Rabaul (PNG) had already fallen, and the Japanese troops were getting much closer. Over the period of a year or more, Darwin and northern parts of Australia experienced periodic bombings from the Japanese. In May 1942, a Japanese invasion fleet departed Rabaul for Port Moresby, and the Battle of the Coral Sea began. It was a very real threat which was only turned back by the US aircraft leaving from carriers. After being turned back by the US, the Japanese then turned their attention to an attack over the Owen Stanley Range via the Kokoda Track, which linked the northern and southern coasts of Papua New Guinea. Thanks to the Papua New Guinean natives assisting the Australians and the US troops, the Japanese were turned back, having to retreat to bases at Buna, Gona and Sanananda, where they were eventually defeated.


Why did Australia fight in New Guinea in World War 2?

Papua New Guinea was important to Japan because they needed a piece of land close enough to Australia so their aircraft would be able to bomb cities and major targets. So Port Morseby was a great place to stage the invasion fleet.Answer Japan had never seriously considered invading Australia, and desired PNG to deny it to the Allies and to neutralise Australia as a base for counter-attack. PNG was important to Australia as a source of raw materials, and was under Australian control under a League of Nations mandate. The Japanese presence there was a huge worry to Australians, who weren't aware that there were no serious Japanese plans to invade Australia.


What led to the battle of the coral sea?

The Battle of the Coral Sea came shortly after the beginning of the war in the Pacific. The Japanese military was concerned that the United States would use Australia as a giant naval and airforce base from which to conduct the war against the Japanese in the southern Pacific and threaten the Japanese oil sources in the nearby Dutch East Indies. The Japanese strategy was to isolate Australia by occupying New Guinea, the Solomon Islands, the New Hebrides, New Caledonia, Samoa and Fiji. The Japanese Navy was dispatched to do the job. There they met the United States Navy -- with their big carriers. The result was the Battle of the Coral Sea. vcs
