From the It’s an Honour Website:
What are anniversary messages?
Australians celebrating a special birthday or wedding anniversary can receive personal congratulations from the Prime Minister, Governor-General or The Queen.
The Prime Minister will send a message of congratulations to people turning 90 years of age or more. The Queen and Governor-General will send a message on a 100th birthday. On request, the Prime Minister and the Governor-General will write again every year and The Queen will write again every five years.
The Prime Minister and Governor-General send messages to couples celebrating 50 years of marriage and subsequent wedding anniversaries. The Queen sends messages to couples celebrating 60 years of marriage and will write every five years after that on request.
|This table below outlines eligibility requirements for Anniversary Messages.

Note: Messages from The Queen can be arranged for couples or individuals who did not receive a message on their 60th wedding anniversary or on their 100th birthday, as the case may be.
How to arrange the message
The best place to start is the electorate office of your local federal member. The electorate staff are there to help.
If you are applying for a message on behalf of a relative or friend who lives in another electorate, their local federal member will be notified so they can send a message too.
You will need to provide supporting documentation like birth certificates or marriage certificates. If these are not available you can provide a statutory declaration. Statutory declaration forms are available at any post office.
Where appropriate, your request to the Prime Minister will be passed on to the Governor-General and The Queen so you only have to make one application.
To arrange a message from the State Premier you should contact the office of your local state parliamentarian.
When to arrange the message
You can make arrangements for anniversary messages up to two months before the celebration.
You can request a belated message up to one month after the birthday or wedding anniversary has passed.
For eligible occasions, requests received within six months after the occasion will be passed to Government House in Canberra for their consideration for a belated message from The Queen.
Where will the message be delivered?
Anniversary messages can be delivered directly to the recipient or to a care-of address for surprises.
