These links provide a starting point to help find member's contact details, however each parliament and legislative assembly site is organised differently. The links take you to the member's pages on state sites.
Australia has a federal system of government with a national parliament and legislative assemblies and councils (parliaments) in each state and territory. Each state except Queensland has a lower house called the Legislative Assembly or House of Assembly, and an upper house called the Legislative Council. The parliaments of Queensland and the two territories only have a Legislative Assembly.
