Government and administration in Australia

How the executive, legislature and administrative state are organised, and which body is responsible for what.

The three branches

Head of State — The Sovereign, represented by the Governor-General
Acts on ministerial advice.
Executive — Prime Minister and Cabinet
Responsible to the House of Representatives.
Legislative — Parliament: House of Representatives and Senate
151 members; 76 senators, 12 per state.
Judicial — Chapter III courts
Federal judges hold office to age 70.

How legislation is made

Bills pass both chambers and receive Royal Assent. A persistent deadlock can trigger a double dissolution and, ultimately, a joint sitting.

Enforcement institutions

Commonwealth Director of Public Prosecutions
Prosecutes federal offences.
Australian Federal Police
Federal policing and national security.
ASIC and ACCC
Corporate, consumer and competition regulators.
