Thanks for your question! Australia has three levels of law-making (often referred to as the three levels of government) – federal, state/territory and local. There are many buildings associated with all three levels of law-making; however, each level has a main meeting place. At a state level this is a parliament. At a local level this is council chambers.
At a federal level, this is Australia's Parliament House in Canberra.
