The Australian War (commonly known as World War III and abbreviated to AW or WW3) was a global military conflict lasting from 2015 to 2018. It involved most great powers, and although many nations did not send troops, most nations took a stance on which side they supported. The reason for the war was a Chinese surprise attack on the Commonwealth of Australia, which eventually lead to the takeover of Australia by China and India (although by then, many citizens and officials had evacuated to escape communism) and the entrance of many nations to the EU and the OAS. This scenario marked the initial first step into a bloody conflict that historians now acknowledge as 'The Strike'.
Course of the War
Declaration of War
By 2015, alliances between India and China (and later Indonesia) had developed, and the two emerging superpowers were hungry for power. After a sneak attack on the city of Darwin on June 22, 2015, with 374 casualties, the Chinese swept through the rural, isolated areas, only a day later issuing a declaration of war. Although Australian forces were being assembled and already beginning slowing down Pan-Asian forces, the delay wouldn't hold up for very long until troops from other NATO countries arrived.
When July arrived, Pan-Asian forces were advancing and had already taken most of the northern part of Australia, and had taken Karratha and Rockhampton with increasing resistance. By this time the ADF (Australian Defence Force) employed a tactic dubbed 'Salting the Earth' by which they would intentionally rig hundreds of rural towns with explosives, mines and drones and contaminated the drinking water.
Brisbane stood for four months but soon was taken, although it is agreed that this was considered a victory that cost the Chinese dearly given SASR troops dropped behind enemy lines cutting the vulnerable supply lines while compromising the ones they couldn't cut. Soon the PLA (Peoples Liberation Army) had taken farther down the east coast and were approaching Sydney, where Coalition forces were waiting for them. The Battle of Sydney resulted in the Pan-Asian Allies taking over Sydney with heavy casualties making it a tactical defeat and a strategic victory for the PAA. The PAA then went on to capture the rest of Australia, except a small part in the west, where the coalition still continued to fight back. Soon however, it marked the event known as 'The Fall'.
By November, the coalition were finally defeated and pushed out of the Australian Mainland. Fighting continued in Tasmania, where the coalition managed to keep the PAA forces at bay for now.
Invasion of Papua New Guinea
While the fighting continued in Australia, the PAA went to turn their focus to Papua New Guinea. On January 3, 2016, Indonesia with the help of China and India begun to storm into Papua New Guinea. The coalition quickly sent military support to Papua, and begun to fight against the PAA forces there. A stalemate occurred for a while, though soon the PAA forces begun to march on after winning the Battle of Vanimo. Three months later, the PAA forces had arrived in Mount Hagen. The city managed to hold out the forces for a month and a half, before falling under PAA control. The PAA forces continued on up until Goroka, where the coalition managed to cause another stalemate there. The stalemate was then broken again just five months later, with the PAA forces taking Goroka and advancing even further.
Meanwhile, Port Moresby and other coastal cities were heavily attacked by the PAA from sea. The coalition mostly suffered heavy defeats, and the PAA forces were able to land at Port Moresby, Morobe, Lae, and others. Despite this, the coalition managed to successfully defend the Bismarck Archipelago and had repelled the PAA forces from there.
On February 5, 2017, Papua New Guinea, minus the Bismarck Archipelago, fell under PAA control, and was annexed into Indonesia a few days later.
New Zealand theatre
The PAA invaded New Zealand on March 2, 2017, at the far northern tip of the island. From there, they managed to make it all the way up to Auckland, before being stopped by the coalition. Soon more coalition forces had arrived and begun to push the PAA out of the North Island. The coalition forces also managed to win some naval battles off the coast, and soon the PAA forces were repelled a year later.
Ceasefire and the Treaty of Beijing
The coalition, struggling to continue on, sues for peace. The PAA agreed, and soon both sides met in Beijing. Australia was to be divided between India and China, while Tasmania was given independence. Indonesia was able to keep Papua New Guinea while the US gained the heavily defended Bismarck Archipelago. New Zealand was to be admitted as the 51st US state.
With this, the Treaty of Beijing was signed on August 14, 2018, thus ending the Australian War.
