Scott Morrison became Prime Minister of Australia on August 24, 2018.
This Statement of Ministerial Standards was issued on August 30, 2018.
The statement was posted on the website of the Department of the Prime Minister and Cabinet. The abstract says:
The Australian people deserve a Government that will act with integrity and in the best interests of the people they serve.
Serving the Australian people as Ministers and Assistant Ministers is an honour and comes with expectations to act at all times to the highest possible standards of probity.
All Ministers and Assistant Ministers are expected to conduct themselves in line with standards established in this Statement in order to maintain the trust of the Australian people.
All parliamentarians are required to disclose private interests to the parliament. Given the additional powers of Ministers and Assistant Ministers, the Prime Minister expects them to provide him with additional information about their private interests to ensure there are no conflicts with their roles as ministers.
This Statement is principles based and is not a complete list of rules. The Prime Minister expects all ministers in the Australian Government to live up to the high standards expected of them by the Australian people at all times.
