Hi! Could you please explain what a half-Senate election is and why this happens. Thanks for your time.

Thanks for your question Luke.

At a half-Senate election, half the state senators and the four territory senators are elected. A half-Senate election is usually held at the same time as elections for the House of Representatives, which must happen at least every three years. This is because state senators are elected for 6 years while territory senators and members of the House of Representatives have 3-year terms. State senators are elected on a rotating basis, with half up for election every three years.

A full Senate election – all 76 seats – only occurs after both the Senate and the House of Representatives have been dissolved – shut down – in a double dissolution.
