Interesting question! All decisions of the Australian Parliament, in both the Senate and the House of Representatives, begin as motions. A motion is a formal proposal made by a senator or member asking the Senate or House to take action of some kind. Decisions are made by agreeing to a motion. For example, the Senate and House the pass bills—proposed laws—by agreeing to a series of motions. Motions are used to refer matters to a committee for investigation or to seek the support of the Senate or House for an issue.
