On August 17, 1914, after nearly two weeks of preparation, Australasia officially launched the Pacific Unification War.
The Army's First and Second Divisions, totaling 32,000 troops, and the Navy's Australasia, HMAS Australia, and New Zealand dreadnoughts, as well as their respective fleets participated in this war.>
Specifically, the plan was for the First and Second Divisions to arrive first at Australian New Guinea and then move on to German New Guinea in the north after repairs were made.
German New Guinea was Germany's largest colony in the Pacific and had the strongest defense among all of its Pacific colonies.
According to the Royal Intelligence Bureau's estimates, there were about 1,000 German guards in German New Guinea, and along with the German civilians there, a force of at least 2,000 could easily be armed.
