According to the
long title of the Australian act, its purpose was "to bring constitutional arrangements affecting the Commonwealth and the States to be brought into conformity with the status of the Commonwealth of Australia as a sovereign, independent and federal nation". The Australia Act (Cth and UK) eliminated the remaining possibilities for the UK to legislate with effect in Australia, for the UK to be involved in Australian government, and for an appeal from any Australian court to a British court. This formally separated all legal ties between Australia and the
United Kingdom.
