This message from Her Majesty is included in the section on the Diamond Jubilee on the ACM site.
On the 60th anniversary of her accession, Queen Elizabeth, Queen of Australia and her other realms and territories, and Head of the Commonwealth, renewed the promise she has made that she would dedicate her whole life to our service. This is a renewal of the promise made to the Commonwealth from Cape Town, South Africa when she turned 21, and made again in the solemn oaths sworn before God at her Coronation. This is her message:
Today, as I mark 60 years as your Queen, I am writing to thank you for the wonderful support and encouragement that you have given to me and Prince Philip over these years and to tell you how deeply moved we have been to receive so many kind messages about the Diamond Jubilee.
In this special year, as I dedicate myself anew to your service, I hope we will all be reminded of the power of togetherness and the convening strength of family, friendship and good neighbourliness, examples of which I have been fortunate to see throughout my reign and which my family and I look forward to seeing in many forms as we travel throughout the United Kingdom and the wider Commonwealth.
I hope also that this Jubilee year will be a time to give thanks for the great advances that have been made since 1952 and to look forward to the future with clear head and warm heart as we join together in our celebrations.
I send my sincere good wishes to you all.
