Thanks for your question!
Senators are elected by the people in their state or territory to represent them in the Senate. Senators discuss state, territory and national issues, debate and vote on bills (proposed laws) and scrutinise (closely examine) government ideas and plans. Sometimes, this involves moving a motion, which is an idea put forward for consideration, debate and decision.
The purpose of moving a motion may be to allow different topics to be heard and discussed in the Parliament. It also allows senators to represent, or speak up about, the concerns and views of their constituents (the people in their state or territory). Although senators may be aware that a motion will fail because a majority of senators do not support it, it is still seen as an important part of the process of representation, law-making and scrutinising government decisions. These are all important roles of the Parliament.
