The Princess Royal, 75, started the second day of her visit by visiting the Hall of Remembrance for a special commemorative service in Sydney, ahead of Remembrance Day on November 11.

Hundreds of well-wishers gathered outside, hoping to catch a glimpse of Queen Elizabeth’s daughter as she was accompanied into the building.

She travelled to the country in her role as Colonel-in-Chief of the Royal Australian Corps of Signals, which she has held since 1977.

Anne – who arrived in Australia on Saturday – looked effortlessly elegant as she stepped out donning a white collared jacket and a long black skirt, which she paired with pointed kitten heels and gloves.

Along with carrying a clutch bag under her arm, the royal also wore a red poppy, a global symbol of respect to the armed forces community, and a golden wreath brooch.

She wore her hair in her signature sophisticated updo as she was greeted by veterans, along with New South Wales Governor Margaret Beazley, Governor-General Sam Mostyn and Chief of Army Lieutenant General Simon Stuart.

Inside the hall, Anne laid down a wreath to pay tribute to those who sacrificed their lives in wars and conflicts, and gave a remembrance reading.

She was then ushered into a car and later travelled to the Victoria Barracks in Sydney, where she attended a parade to mark the Centenary of the Royal Australian Corps of Signals.

King Charles’s sister appeared smart and polished as she proudly sported an Australian army uniform complete with medals, as she stood alongside her husband, Sir Timothy Laurence.

The former navy officer looked dapper in a suit and tie as he donned a red poppy and his golden medallions.

Anne also inspected the Australian guards and smiled as she conversed with both junior and senior members of the forces.

Later on, she attended a garden party with 900 military guests in the Victoria Barracks grounds.

‘One hundred years of service, innovation and dedication is a remarkable milestone, and it is indeed a privilege, as your colonel in chief, to share in this occasion,’ Anne said in her speech, according to News.com.au.

‘Over the past century, the Royal Australian Corps of Signals has played a vital role in every theatre of operations where our defence force has served, from the trenches of the First World War to modern operations across the globe, your work has enabled communications, co-ordination and connectivity, often under the most challenging circumstances.’

She continued by saying that the Latin cause motto, Certa Cito – which means swift and sure – reflects the force’s ‘professionalism, speed and reliability’.
