Electoral system of Australia
The Australian Senate has 76 members: each of the six states elects 12 Senators, and the Northern Territory (NT) and the Australian Capital Territory (ACT) each elect two Senators. The several other Australian Territories have very small populations and are represented by Northern Territory and ACT Senators (for example, Christmas Island residents are represented by NT Senators, while Jervis Bay Territory residents are represented by ACT Senators).
