President of the Senate (Australia)
The position is provided for by Section 17 of the Constitution of Australia. The Senate elects one of its members as president at the start of each new term, or whenever the position is vacant. This is usually—though not necessarily—a member of the party or coalition that holds the most seats in the Senate. The largest party in the Senate is not always the governing party, as government is determined by the House of Representatives. The President of the Senate and the Speaker of the House of Representatives may consequently be from different parties.
Cabinet of South Australia
The Cabinet of South Australia is the chief policy-making organ of the Government of South Australia. In South Australia, the cabinet is interchangeably known as the ministry as there is no "outer ministry" – therefore all ministers are in cabinet. The current fourteen-member cabinet, the Marshall Ministry, is headed by Premier Steven Marshall of the South Australian Division of the Liberal Party of Australia.
