The Standing Orders provide that there will be both a Deputy Speaker and an Assistant Speaker.
Both the Deputy Speaker and the Assistant Speaker are elected on the first sitting day of each Parliament, or whenever either Office becomes vacant.
A Member is elected Deputy Speaker or Assistant Speaker by motion (notice is not required). The Deputy Speaker holds office past the expiration of the Legislative Assembly until a successor is elected. This is because the Constitution Act 1902 provides for the Deputy Speaker to act in place of the Speaker when he or she is absent from the State. The Assistant Speaker holds office for the duration of the Parliament unless the House otherwise directs and ceases to hold office when the Assembly expires by effluxion of time or is dissolved by the Governor.
The Assistant Speaker certifies that a bill originating in the Assembly which is to be presented to the Governor for assent is the same as that which was passed by both Houses.
The Deputy Speaker and Assistant Speaker have the same authority as the Speaker when presiding in the Chair.
The Deputy Speaker is the Honourable Leslie Williams MP.
The Assistant Speaker is Mr Greg Piper MP.
Absence of the Speaker, Deputy Speaker or Assistant Speaker
At the beginning of each Parliament, the Speaker nominates Members who will be Temporary Speakers. They relieve the Speaker, Deputy Speaker and Assistant Speaker on a temporary basis whenever requested.
The current Temporary Speakers are:
The Clerk of the Legislative Assembly is Ms Helen Minnican.
The Serjeant-at-Arms of the Legislative Assembly is Mr Simon Johnston.
