WACE ATAR Politics and Law cheat sheet

Australia is a constitutional monarchy and a representative democracy; the King is head of state, represented federally by the Governor-General and in each state by a Governor.

The Commonwealth Parliament is bicameral: the House of Representatives (151 members, single-member electorates, three-year maximum term) and the Senate (76 senators, 12 per state, 2 per territory, six-year terms with half-Senate elections).

The executive comprises the Prime Minister and ministry drawn from Parliament and is responsible to it; the Governor-General exercises formal powers on ministerial advice, with reserve powers available in rare circumstances.

Section 61 vests executive power in the King exercised by the Governor-General; s 62 establishes the Federal Executive Council; s 64 requires ministers to be members of Parliament.

The High Court of Australia sits at the apex of the judicial hierarchy; it has original jurisdiction under s 75 and hears appeals under s 73, and its interpretation of the Constitution is binding on all courts.

Westminster conventions operating in Australia include responsible government, ministerial responsibility, collective cabinet solidarity, and the Governor-General acting on advice.

Separation of powers is partial: the legislature and executive are fused through the ministry, while Chapter III courts are kept separate from non-judicial functions (the Boilermakers' principle).

The Australian Public Service and statutory bodies (for example the Australian Electoral Commission and the Reserve Bank) implement policy and administer legislation independently of day-to-day ministerial direction.

Voting is compulsory in Australian federal elections under the Commonwealth Electoral Act 1918; eligible voters must enrol and cast a formal or informal ballot, with administrative penalties for non-voting.

The House of Representatives uses full preferential voting in single-member electorates; a candidate must obtain an absolute majority after preferences are distributed.

The Senate uses proportional representation by the single transferable vote across multi-member states and territories, producing a quota threshold of roughly 1/(seats+1) plus one vote.

Compulsory enrolment, independent administration by the Australian Electoral Commission, and public funding with disclosure of donations are core integrity mechanisms.

Minor parties and independents gain representation more readily in the Senate than the House because of the proportional system and larger electorates.

Participation channels include elections, referendums, party membership, petitions to Parliament, submissions to parliamentary committees, lobbying, protests, and social media campaigns.

The Commonwealth franchise is set by s 30 and s 51(xxxvi) of the Constitution, subject to the principle that Parliament cannot exclude adult citizens from voting without a substantial reason (Roach v Electoral Commissioner).

Section 44 disqualifications (dual citizenship, foreign allegiance, undischarged bankruptcy, certain offices of profit) shape candidate eligibility and have led to High Court referrals sitting as the Court of Disputed Returns.

The Commonwealth Constitution is contained in clause 9 of the Commonwealth of Australia Constitution Act 1900 (UK) and came into operation on 1 January 1901.

Section 51 enumerates concurrent Commonwealth powers (for example trade and commerce, taxation, defence, external affairs, corporations, marriage); s 52 lists exclusive Commonwealth powers.

Section 109 provides that when a valid Commonwealth law and a valid state law are inconsistent, the Commonwealth law prevails and the state law is invalid to the extent of the inconsistency.

Residual powers remain with the states; the states also retain their own constitutions, subject to the Commonwealth Constitution and the Australia Acts 1986.

Section 96 grants the Commonwealth power to make conditional financial grants to the states, a key mechanism of cooperative federalism and policy influence.

Section 128 requires a referendum to alter the Constitution: an absolute majority in each house, then a double majority of a national majority plus a majority in at least four of the six states.

Key doctrines include the implied freedom of political communication (Lange v Australian Broadcasting Corporation), the Melbourne Corporation doctrine protecting state integrity, and the Engineers' case approach to literal interpretation.

Referendum history: 44 proposals have been put, with 8 carried; success requires bipartisan support, clear and simple proposals, and broad state endorsement.

The court hierarchy: High Court, then Federal Court and state Supreme Courts, then District/County Courts, then Magistrates/Local Courts; appeals move upward, with leave required for the High Court.

Criminal matters require proof beyond reasonable doubt; civil matters use the balance of probabilities; the adversary system relies on party-presented evidence and impartial adjudication.

The rule of law requires that law apply equally, that it be publicly known and prospective, and that government action be authorised by law and reviewable by independent courts.

Australia has no national bill of rights; rights derive from statute, common law, and the Constitution, and are protected by mechanisms such as the implied freedom of political communication and the separation of judicial power.

Statutory interpretation uses the text, context, and purpose of legislation, with extrinsic materials permitted by the Acts Interpretation Act 1901 (Cth).

Doctrine of precedent: superior court decisions bind lower courts in the same hierarchy; the High Court may depart from its own earlier decisions.

Alternative dispute resolution (mediation, conciliation, arbitration, negotiation) is encouraged by courts and tribunals to reduce cost and delay; tribunals such as the Administrative Appeals Tribunal review administrative decisions.

The adversarial system is distinguished from the inquisitorial model used in civil law jurisdictions, which places greater investigative responsibility on the court.

Law reform occurs through parliamentary amendment, High Court interpretation, referendum, and reference by law reform bodies such as the Australian Law Reform Commission and state law reform commissions.

Mabo v Queensland (No 2) (1992) recognised native title in Australian law, overturning the doctrine of terra nullius; the Native Title Act 1993 provided the statutory framework.

The Senate's proportional representation system uses a quota of votes calculated as total formal votes divided by (seats plus one) plus one.

Preferential voting in the House means a candidate must secure an absolute majority after preferences; the two-party preferred result is used to measure electoral support.

The Australian Electoral Commission administers federal elections, maintains the electoral roll, and enforces disclosure and funding rules under the Commonwealth Electoral Act 1918.

Parliamentary committees conduct inquiries and public hearings, providing a structured participation channel for citizens and interest groups.
