Parliamentary committees are one mechanism the House uses to keep a check on the activities of the Government. Because they have extensive powers to call for people, including public servants, and documents to come before them, committees can thoroughly investigate questions of government administration and service delivery.

Committees can contribute to better informed policy-making and legislative processes. They help Members to access a wide range of community and expert views so that through the committee process, the Parliament is able to be better informed of community issues and attitudes.
