Australia is far away from Europe, why did it actively join the Commonwealth War Group during World War I?

Australia lies in Oceania. At that time, World War I was mainly the result of the intensification of contradictions in some imperialist countries in Europe. In the southern hemisphere, Australia can be said to be "unaffected", and this war has little to do with them. The Australian Prime Minister even shouted out the slogan of "supporting Britain as much as I can, even if it is the last person's breath", which is puzzling.

From the historical origin, there is a historical basis for Australia to actively participate in the war and rescue Britain. In the era of great navigation, Britain, as a maritime hegemon, constantly occupied new colonies and invaded and expanded abroad. Australia, a fresh land, was once a British colony. Although Australia was politically independent at that time, the head of state at that time was still regarded by China people as the Queen of England, so the British had a deep influence on them.

Secondly, because Australia is a newly reclaimed colony, there are not many indigenous people who died suddenly. So at that time, most people in Australia were British immigrants, and they still relied on and trusted Britain from the heart. The war situation at that time was mainly the battle between the two sides. One is the allies, that is, Germany is the main country. The other is an ally, mainly Britain. Both sides thought that the war could be solved in a few months, but it actually lasted for four years, which brought them great disasters. Australia also shined brilliantly in this war and won many praises from the Allies. The international status has been significantly improved, the people's sense of honor and gain has been greatly improved, and the national self-confidence has been greatly enhanced. They proudly said, "I am Australian!" "
