So is the flag of Hawaii and New Zealand. They used to be outposts of the British Empire, is the simple and short answer.
I think it's because Australia used to be a penal colony for Britain. I think that's why Austrailians are so crazy. They all descended from criminals.
They usually relate back to things the UK conquered, Australia was originally a British colony and the flag reflects that.
They are not just because have the same colours and signs
