To mark significant birthdays or wedding anniversaries, residents may apply for a congratulatory letter.
Catherine’s office can arrange for a letter from herself, the Prime Minister, Premier, Governor General and His Majesty the King (depending on the milestone).
For more details of the messages available for different occasions see pmc.gov.au/government/anniversary-messages
Please note that documentation like marriage certificates or ID are required to arrange congratulatory messages. Please reach out to the office for more information.
