Why did Australia participate in the First World War?

Australia is a British colony, and many local people are British. At that time, the slogan was: in order to defend the motherland, Australia at that time mainly fought against Turkey, and the famous battle was the Battle of Grepuri. At that time, for Australia, because of the war, women went to society and no longer lived a life of taking care of children and families, but went to work in factories to supplement their families.

At that time, it was mainly aimed at Turkey, and now there are festivals in Australia to spend a few years with those soldiers, which seems to be 165438+ October. . .
