For a parliament to effectively perform its functions, it must ensure a high level of integrity of its Members and its operations. The public’s trust in its elected Members of Parliament is a fundamental aspect of good governance and an open, democratic society.

Members of Parliament have individual responsibility for the functioning and integrity of the Parliament in two fundamental ways:
1. By upholding the ideals of democratic government, particularly by respecting the separation of powers and the rule of law; and
2. By demonstrating high standards of integrity and ethical behaviour, including workplace behaviour, consistent with their important public interest roles, especially when they are making laws for their community and scrutinising the government.

Codes of conduct for Members and standards of behaviour expected of all persons at the parliamentary workplace can help a parliament to function with integrity, to encourage ethical behaviour, and build public trust.
