- Both have a House that is popularly elected with electorate size determined by voting population.
- Both have a Senate that represents the States equally – 2 senators per state in the US, 12 per state in Australia. Senators in both countries serve 6 year terms.
- All legislation must be passed by both houses of parliament.

Difference between Australia and the USA.
- The US is a republic, whereas Australia is a constitutional monarchy. The US president is both head of state and head of government and is directly elected by the people. Australia’s head of state is the British monarch who is represented by a Governor-General chosen by the Prime Minister.
- In Australia, the government (ministry, cabinet, executive) is drawn from the parliament and responsible to it, whereas in the US the Executive branch of government is independent of the congress and no person may be a member of congress and a minister simultaneously.
- The Australian Prime Minister is chosen by the elected members of the party/parties that have won a majority of seats in the House of Representatives, whereas the US President is directly elected by the people and must appoint non-members of the congress to fill ministerial posts.
- Members of the Australian House of Representatives serve a 3 year term whereas US members of the House serve 2 years.
- Elections in the US are on set days for fixed terms, whereas an Australian Prime Minister may dissolve Parliament and call an early election.
- Electoral enrolment and voting is compulsory in Australia, but voluntary in the US.
- Party discipline is not as tight in the US as it is in Australia, leading to a situation where members of both parties will often form changing voting alliances on legislation.
- Legislation in the US requires both legislative approval and the president’s signature, whereas in Australia legislation is automatically ratified by the Governor-General once passed by both houses.
