It's because the English came and took over Australia along with the Aboriginals and by that I mean the Aboriginals were kicked off the land and most of them were killed because they refused. Also Australia was colonized by the English. There for we are part of the UK and have adopted a similar form of government and choose to remain part of the UK.
The English hardly "took over" Australia - they had no idea how large it was. They did establish colonies in Australia. You offer no evidence that Aboriginals were "kicked off the land" (Into the ocean?) and that most of them were killed because they refused, and this isn't relevant to the question anyway.
