Father of the Australian Senate
In Australian parliamentary practice, the Father of the Senate is the senator in the Australian Senate who has served longer, continuously, than any other currently serving senator. The title is seldom used today. It is an informal, honorific title which carries no parliamentary responsibilities. Where two or more senators have had equal lengths of continuous service, more than any other currently serving senators, they are known as the joint Fathers of the Senate. The current Father of the Senate is Ian Macdonald who acquired the status on 6 February 2015 after the resignation from Parliament of the then Father of the Senate, John Faulkner.
