The Prince of Wales and Duchess of Cornwall have started greeting the thousands who have lined up to meet them in Sydney's CBD.
Members of the public have been gathering in Martin Place through the morning waving Australian flags, while others have secured views from surrounding office buildings in the hope of catching a glimpse of the royals.
Leah Hutching managed to secure a prime front-row position while job hunting in Martin Place and told AAP she's hoping to ask the prince and duchess for some work experience in the royal household.
The royal couple earlier toured the NSW Mounted Police barracks to mark 190 years of the oldest continuous mounted police unit in the world.
Joined by NSW Police Commissioner Andrew Scipione and Police Minister Troy Grant, the group was treated to a display of mounted troop drills, crowd control and an arrest display during a performance led by Sergeant Karen Owen.
With 32 years of experience, she is the longest-serving female mounted police officer in NSW. Members of the Riding for the Disabled Association also put on a display before the prince and duchess signed the guest book.
The Duchess then made her way to OzHarvest while Prince Charles arrived at Macquarie Group for a series of talks with firefighters, police and Red Cross nurses about mental health after disasters like the Lindt cafe siege, shootings and bushfires.
The Prince was greeted by former Australian defence force chief Sir Angus Houston and Prince's Charities Australia chief executive Janine Kirk.
