This is a list of Members of the Parliament of Australia who have served for at least 30 years.
Their service does not need to be continuous; broken terms are aggregated.
All these periods of service were spent in one House exclusively. A number of people have served in both the Senate and the House of Representatives, but none of them to date has had an aggregate length of service to the Parliament reaching 30 years.
Those who were Father of the Senate or Father of the House of Representatives are shown. A Father of either House is the person currently serving who has served longer, continuously, than any other currently serving member of that House. Where two or more people have equal lengths of continuous service, more than any other people, they are called joint Fathers. The more senior of the Father of the House and the Father of the Senate is the Father of the Parliament. Only those Fathers who served for 30 years or more will appear in this list.
No woman yet appears on this list. Bronwyn Bishop served in the Australian parliament longer than any other woman, in October 2014 outstripping the record of 27 years and 119 days previously held by Kathy Sullivan. At the end of her term at the 9 May 2016 double dissolution, Bishop had served for 28 years and 274 days.
