Queen Camilla accidentally breaks royal protocol while meeting a fan in Australia

broke royal protocol on Sunday after she agreed to a "selfie" with one royal fan during her first day of engagements in Australia.

King Charles and Queen Camilla are currently on their first royal tour to Australia and Samoa since the King's ascension to the throne and their first day included in Sydney for the Sunday church service.

After the service, the royal couple went outside the church to shake hands with well-wishers, who numbered around two hundred people, with some waiting since 5am to catch a glimpse of the royals.

There, the Queen was caught posing for a selfie with a young royal fan.

While there is no royal rule regarding selfies, it is generally discouraged for members of the Royal Family to pose for selfies.

The protocol has been breached many times in the past by royals including King Charles, who recently posed for a selfie picture with New Zealand's women's rugby team last month.

Elsewhere, the King spotted an old friend, his former polo teacher Sinclair Hill, described as Australia's greatest player of the sport.

He was joined by his wife Wendy Hill who was kissed on both cheeks by Charles and said afterwards: "He is a lovely man and the fact that he has not been well and still came... The effort he puts in to talk to all these people. I thought he looked terrific."

Earlier in the day, the monarch attended commemorations marking the 150th anniversary of the Legislative Council in 1974 of New South Wales.

He said in a speech to guests: "Democratic systems must evolve, of course, to remain fit for purpose, but they are, nevertheless, essentially sound systems, as I said in this building 50 years ago.

"When underpinned by wisdom and good faith, democracy has, I believe, an extraordinary capacity for innovation, compromise and adaptability, as well as stability.

"Moreover, strong parliamentary systems, like the one we celebrate on this special occasion, are fundamental to the democracies that serve today's diverse societies; and are even more vital, given the ever-changing natural, social, economic and technological environment."
