Kokoda campaign

Kokoda campaign? Why is it significant for Australia? Did it shape Australia for what it is now?
Good Morning 9T today I will be answering the unanswered question of the Kokoda campaign.
The Japanese and Australians force battled from July to November in 1942. The Japanese force arrived on the Northern Coast of Papua and followed the Kokoda track to isolate the Australians from the United States and tried to take hold of Papua. The Japanese force needed Southern Coast of Port Moresby to seize Papua. The Japanese force required Papua if they wanted to use as a home base for them to undertake Australians mainland.
