When someone decides they want to be a member of parliament, they must choose if they want to be a senator or a member of the House of Representatives.
Section 43 of the Australian Constitution says that a person can only be a member of either the Senate or the House of Representatives; they cannot be a member of both. This means, for example, a senator cannot be a candidate for a seat in the House of Representatives without first resigning from the Senate.
