The couple had been later welcomed by followers who had lined the steps of the Sydney Opera House, the place they boarded a ship for a crusing occasion hosted by Invictus Australia.
The couple met veteran Joel Vanderzwan on the harbour, who introduced them with customised flip-flops that includes the messages ‘G’day Hazza’ and ‘G’day Megs’.
After accepting the presents, Harry joked that he usually receives “budgie smugglers” from Invictus Australia.
The couple then headed out onto the water on a vessel designed to be wheelchair-accessible, so injured veterans may board.
In 2018, Prince Harry introduced that Australia would host the Invictus Games throughout his royal tour, a contest he based in 2014 for wounded navy veterans.
It is the couple’s first journey to Australia since that 2018 tour.
Michael Hartung, chief government of Invictus Australia, described Harry and Meghan’s return to Sydney Harbour as a “full-circle moment”.
The couple are not working royals and have been visiting the nation in a personal capability.
