Section 13 of the Constitution of Australia

Section 13 of the Constitution of Australia provides for three aspects of the terms of members of the Australian Senate: the timing of elections, the commencement date of their terms and for the Senate to allocate long (six-year) and short (three-year) terms following a double dissolution of the Parliament of Australia.^[1] While members of the House of Representatives and territory senators have a maximum three-year term, state senators have a fixed six-year term, subject only to the parliament being dissolved by a double dissolution.
