Nov 11, 2025

Overview

Intro to the structure and functions of Australia’s federal government, key roles, elections, and how laws are made.

Key Political Roles

  • Monarch is Australia’s head of state; largely ceremonial, appoints Governor-General on PM’s advice.
  • Governor-General grants Royal Assent, sets election dates, appoints ministers on PM’s advice.
  • Prime Minister leads party/coalition with majority in House of Representatives.
  • Deputy Prime Minister acts for PM when absent; other senior ministers can act if needed.
  • Leader of the Opposition leads the party with the second-most House seats.
  • Ministers head portfolios (e.g., Health, Defence); collectively front bench or Cabinet.
  • Shadow Ministers mirror portfolios in opposition; develop alternative policies.
  • Backbenchers are MPs/Senators without special roles; vital for tight votes.
  • Crossbench includes minor parties and independents; often hold balance of power in Senate.

Parties and Coalitions

  • Major groupings: Liberal Party (right-wing), Labor Party (centre), Nationals (right-wing, regional).
  • The Coalition is a formal Liberal–National alliance; votes together on bills.
  • Minor parties more successful in Senate due to quota system and statewide voting.
  • Historical PM-producing parties include Protectionist, Free Trade, Nationalist, and others.

Parliament Structure

  • Bicameral: House of Representatives (lower house) and Senate (upper house).
  • Current seats: 151 House members; 76 Senators; numbers have grown over time.
  • Electorates based on population, not area; city seats small, rural seats very large.
  • House members represent single local electorates; Senators represent states/territories.

Elections and Voting

  • Federal elections are not fixed-date; called within a constitutional window via Governor-General.
  • Voting is compulsory; managed by the Australian Electoral Commission (AEC).
  • Enrol from age 16; voting age is 18; AEC supports diverse voter needs.
  • Two ballots: green for House (rank all candidates), white for Senate (large, two methods).
  • Preferential voting lets preferences transfer until a candidate wins.

House vs Senate Voting

  • House: single-member electorates; must number every box in preferred order.
  • Senate: 12 per state, 2 per NT and ACT; statewide contests use quotas.
  • Senate ballot has above-the-line (number at least 6 parties) and below-the-line (number at least 12 candidates).
  • Above-the-line selects party preferences; below-the-line offers precise candidate ordering.

Terms and Election Cycles

  • House terms are three years; all seats generally contest together.
  • Senators serve six years; usual half-Senate elections align with House elections.
  • Double dissolution: all seats in both houses contest; used after certain legislative deadlocks.
  • After double dissolution, half of elected Senators receive three-year terms to reset cycle.

Law-Making Process

  • Bills can start in either house, except money bills must start in the House.
  • Origin house debates and passes bill; second house can pass or request amendments.
  • Disagreement on amendments can cause bill to fail; repeated Senate rejection can be a double dissolution trigger.
  • Governor-General grants Royal Assent after both houses pass a bill.

Hung Parliament and Confidence

  • No majority in the House is a hung parliament; parties seek confidence and supply from crossbench.
  • Agreements may form coalitions or support arrangements; failure can trigger a new election.
  • 2010 example: Gillard formed government with independents and one Greens MP.

Crossbench and Balance of Power

  • Minor parties and independents can decide outcomes, especially in the Senate.
  • Government negotiates with crossbench to pass legislation; sometimes a single vote is decisive.
  • Voters for minor parties influence policy via crossbench leverage.

Electorates and Representation

  • Inner-city electorates are small; rural electorates can be massive due to sparse populations.
  • Smallest example: Grayndler (approx. 32 km²); largest example: Durack (~1.6 million km²).
  • Voting patterns can correlate with local demographics and interests.
