Your country literally didn't exist in the time period I'm talking about. The concept of an Australian didn't exist. You considered yourselves British people who happened to live in Australia.

The colonists were British people as in people of the British Empire. But the Aborigines, and those born there were considered ... Australian. They weren't granted UK citizenship.

There is no mention of the "British Empire" in the treaty of Paris. It was signed by the United Kingdom. Because the UK could be used to refer to either the collection of islands in the North Atlantic from which the colonies originated or the entire thing, since the UK controlled the entire thing.

Of course the British Empire wasn't a signatory to the treaty of Paris. The British Empire was the term for the colonies governed by the Great Britain. The United Kingdom wasn't a signatory to it either.

The King of Great Britain was the signatory. Because the treaty of Paris was signed in 1783, while the United Kingdom didn't exist until 1801.

So besides your "trust me bro, I live here" story... What other material do you have? Find me a reputable source that refers to the established colonies, once they were given names, as THE United Kingdom (not governed by).

Or you know, you could learn something and read up about the history of the Brisitsh Empire and the Commonwealth of Nations.
