query: Does Australia have a two-party system?
passage: Politics of Australia
The politics of Australia take place within the framework of a federal parliamentary constitutional monarchy. Australians elect parliamentarians to the federal Parliament of Australia, a bicameral body which incorporates elements of the fused executive inherited from the Westminster system, and a strong federalist senate, adopted from the United States Congress. Australia largely operates as a two-party system in which voting is compulsory.[1] The Economist Intelligence Unit has rated Australia as a "full democracy" in 2017.[2]
passage: Political party
Australia, Canada, Nepal, Pakistan, India, Ireland, United Kingdom and Norway are examples of countries with two strong parties and additional smaller parties that have also obtained representation. The smaller or "third" parties may hold the balance of power in a parliamentary system, and thus may be invited to form a part of a coalition government together with one of the larger parties, or may provide a supply and confidence agreement to the government; or may instead act independently from the dominant parties.
