The Westminster system is the foundation of Australian democracy. Named after the Palace of Westminster in London, it is the British model of parliamentary government that Australia adopted and adapted during Federation in 1901.
Its core principles ensure that power is not held by one person, but is distributed through a series of “checks and balances.”
1. The Three Core Pillars: Separation of Powers
The most important feature of the Westminster system is that it divides the power to run the country into three distinct branches:
- The Legislature (Parliament): The body that debates and makes the laws. In Australia, this is usually bicameral, meaning it has two houses: the House of Representatives (Lower House) and the Senate (Upper House).
- The Executive (Government): The branch that puts laws into action. This includes the Prime Minister, the Cabinet (senior ministers), and government departments.
- The Judiciary (Courts): Independent judges and courts that interpret the law and ensure that both the government and the people follow it.
2. The Principle of "Responsible Government"
In a Westminster system, the government is not separate from the parliament; it is born from it. This is known as Responsible Government.
- Drawn from Parliament: The Prime Minister and all Ministers must be elected members of Parliament.
- Accountability: The Executive (the government) is “responsible” to the Parliament. This means they must answer questions during “Question Time” and can be dismissed if they lose the “confidence” (majority support) of the Lower House.
- The Opposition: A “Loyal Opposition” sits opposite the government. Their job is to scrutinize the government’s every move, offering an alternative vision for the country.
3. The Ceremonial Head of State
The Westminster system features a Constitutional Monarchy. This means we have a Head of State (the King) who is separate from the Head of Government (the Prime Minister).
- The Governor-General: Since the King lives in the UK, he is represented in Australia by the Governor-General.
- Neutrality: The Governor-General’s role is almost entirely ceremonial. They sign bills into law (Royal Assent) and open sessions of Parliament, but they only act on the “advice” of the Prime Minister. This keeps the highest office in the land “above politics.”
4. An Apolitical Public Service
A key “hidden” part of the Westminster system is the Public Service (the “bureaucracy”).
- Permanence: Unlike in some other systems (like the US), where thousands of government workers change when a new leader is elected, Australia’s public servants are permanent.
- Impartiality: They are required to be apolitical. They provide “frank and fearless” advice to whichever party is in power, ensuring that the country’s administration continues smoothly even when the government changes.
