Who can use the title Honourable?

A Member or Senator who becomes a Minister is appointed to the Executive Council and thus has the title ‘Honourable’ while they remain Executive Councillors. It rests with the Governor-General to continue or terminate membership of the Executive Council and consequently the right to the title. With one exception, Ministers appointed to the Executive Council have not in the past had their appointment to the Council terminated upon termination of their commission and hence have retained the title ‘Honourable’ for life. Parliamentary Secretaries also have the title ‘Honourable’ when, as has been the recent practice, they have been appointed to the Executive Council. It is established custom for a Member who is elected Speaker to use the title ‘Honourable’ during his or her period of office and to be granted the privilege of retaining the title for life if he or she serves in the office for three or more years.
