Japan sought to capture Port Moresby by an overland route through the Owen Stanley Range, aiming to isolate Australia from the United States and consolidate its Pacific dominance. Following failures at the Battle of the Coral Sea to take Port Moresby by sea, the Japanese South Seas Detachment landed near Gona and Buna on 21 July 1942 to pursue the overland Kokoda Track approach.
Japanese forces rapidly advanced along the Kokoda Track, pushing outnumbered Australian and Papuan troops back toward Port Moresby. After reaching within sight of the city, the Japanese were ordered to withdraw on 26 September due to overstretched supply lines and setbacks at Guadalcanal. Australians then pursued and defeated Japanese forces at Oivi–Gorari in November before crossing the Kumusi River to assault the Buna–Gona beachheads.
The campaign resulted in a decisive Australian victory and permanently ended Japan's threat to Port Moresby. It exposed severe deficiencies in Australian jungle doctrine, training, and equipment, prompting widespread reforms. The removal of three senior Australian officers amid a command crisis, and debate over MacArthur's and Blamey's leadership, left lasting controversy. The campaign became deeply embedded in Australian national memory as a symbol of military endurance.
