Common law rights, human rights scrutiny and the rule of law.
Australia is unusual among common law or "liberal democracy" countries in not having a Constitutional Charter or Bill of Rights.
However, common law courts (such as the Australian High Court) have power to provide significant protection of human rights principles including the rule of law, except where legislation specifically overrides this power. (Extract from Australian Human Rights Commission - see here)
And the reason why we do not a Constitutional Charter or Bill of Rights, is because our Politicians have, over many years) do not wish us this right, as they have 'corporatised' themselves in order to act under Corporate, Commercial or Statutes Law.
If you search, for example, Dunn and Bradstreet's Database of Corporations, we will find some 60 Federal Government Departments, acting as Corporate Entities. John Harris explains the significance of this more very well - see here.
Increasingly, people see the corruption holding our nation captive and. with urgency, seek a resolution to return our Great South to the sovereign people..see below for more.
Common Law principles need to be written into a new Australian Constitution as the current ones (1900, 1901 or 1973) are only about the political voting system, and not about the people.
