Constitutional history of Australia

The Constitutional history of Australia is the history of Australia's foundational legal principles. Australia's legal origins as a nation state began in the colonial era, with the reception of English law and the lack of any regard to existing Indigenous legal structures. As the colonies expanded, Australia gradually began to achieve de facto independence. Over the years as a result the foundations of the Australian legal system gradually began to shift. This culminated in the Australia Act, an act formally ending legal ties with the UK.
