Father of the Australian Parliament
In Australian parliamentary practice, the Father of the Australian Parliament is the more senior of the Father of the Senate and the Father of the House of Representatives. It is an informal, honorific title which carries no parliamentary responsibilities. Where two or more parliamentarians have had equal lengths of continuous service, more than any other currently serving parliamentarian, they are known as the joint Fathers of the Parliament. The current Father of the Parliament is Senator Ian Macdonald who has held the title since 10 May 2016.
