The Abuse of the External Affairs Power by the Globalist Left
The Australian Constitution was sold as a bargain between a new national government and the colonies that became states. Canberra would handle defence, customs, currency, and relations with the outside world. Almost everything else: land, rivers, energy, schools, hospitals, the ordinary police power, would stay closer to the people who lived with the consequences. Section 51(xxix), the external affairs power, looked like the unglamorous clause that let the Commonwealth speak for Australia abroad. After the High Court finished with it, that clause became a machine for turning international paper into domestic command.
The turning point was not a quiet technicality. In Commonwealth v Tasmania in 1983 the Hawke government used the World Heritage Convention to stop a dam the Tasmanian parliament wanted built on the Gordon–Franklin. Four judges held that once Australia had entered a bona fide treaty, the Commonwealth could legislate in terms "appropriate and adapted" to the obligation, even if the subject was a river in a state and even if no other head of power would have authorised the statute. The dam was inside Australia. The voters who wanted it were Tasmanian. The veto arrived from Paris via Canberra. That is the template. Sign first, legislate later, and the federal compact shrinks to whatever residual the treaty texts have not already eaten.
Progressive governments and their institutional allies did not invent treaties. They noticed what the Dam case made possible and then industrialised it. Human-rights covenants, environmental conventions, labour instruments, heritage listings, climate accords, and public-health frameworks became a second constitution written in Geneva, New York, and Paris. The executive signs. Implementation statutes follow, often years later, dressed as fidelity to "our international obligations." Subjects the founders left with the states: land use, energy mix, speech adjacent to "hate," family policy, medical administration, acquire a federal overlay because a committee somewhere produced a text and a minister put a signature on it. The political advantage is obvious. Policies that would lose a referendum or a state election can be imported as duty. Opposition can be framed as isolationism rather than as a defence of self-government.
The racket is not that every treaty is a plot. Trade agreements and genuine security pacts are old tools of statecraft. The distortion is the use of open-ended, hortatory instruments as rocket fuel for a domestic program that could not be enacted on its own merits. Climate treaties and net-zero architecture are the current exhibit. Paris and its descendants do not contain a clause that says "shut the coal industry on a timetable designed in Europe." They create a diplomatic and legal weather system in which Canberra can claim that energy policy is no longer a national choice but an external affair. The same pattern appears in health. Pandemic instruments and International Health Regulations are sold as cooperation. Critics hear a rehearsal for the next round of emergency centralisation, with WHO language standing in for a debate the Australian parliament never quite has. Migration compacts work the same way: domestic border policy is re-described as compliance with a global text, and dissent becomes a breach of tone rather than an argument about numbers and consent.
Federalism is the first casualty. If the Commonwealth can manufacture a new head of power by accession, the states are tenants at will. The High Court has not required that a treaty be specific, that it concern something geographically external, or that the implementing law be the least intrusive means. "Reasonably capable of being considered appropriate and adapted" is a test that favours the legislator who wrote the statute. Combined with the corporations power and the grants power, external affairs turns the Federation into a holding company whose subsidiaries implement whatever the national office has promised foreigners.
Democratic procedure is the second casualty. Treaties are still, at the decisive moment, an executive act. Parliamentary committees can inspect, delay, and scold. They cannot easily stop a government that wants the domestic hook. Voters do not get a clause-by-clause campaign. By the time an implementing bill appears, the moral frame is already set: we have given our word. That is a respectable principle in diplomacy. It is a rotten principle when the word was given in order to bind people who were never asked.
None of this requires a cartoon of one party as uniquely wicked. Coalition governments signed instruments too, and they used the same power when it suited them. What has changed is the volume and the ambition of the progressive project: climate, identity, public health, and "rights" texts that read like policy platforms. The Left discovered that the shortest path around the Australian voter runs through an international secretariat. Call that globalism or call it legal entrepreneurship. The effect is the same. National law bends toward the priorities of people who do not face an Australian ballot.
That is why a party shouting about sovereignty finds oxygen. One Nation's rise is not explained only by migration or energy bills. A slice of the electorate has concluded that the major parties treat international process as higher law and treat popular resistance as a public-relations problem. Withdrawal talk, Paris, WHO, selected UN frameworks, is crude, and crudeness is part of the point. It names the mechanism the respectable parties prefer to leave unnamed: the external affairs power as a laundering service for agendas that cannot win cleanly at home.
The remedy is not to pretend Australia can live without agreements. It is to put the hook back on the executive. Require implementing legislation before ratification bites. Narrow the Dam doctrine so a treaty cannot conjure federal power over every subject a preamble mentions. Give the Senate a real veto, not a seminar. And stop confusing "the international community" with a constituency. A self-governing country can cooperate. It cannot remain self-governing if every unfinished argument in Canberra can be outsourced to a text that nobody here was allowed to amend.
