Dressed in a black shirt with the logo of the sporting event he helped to kick start in 2014, the British royal ascended the 134 meter (439 foot) high landmark in beautifully sunny weather, accompanied by Australia’s Prime Minister Scott Morrison.
It will be the fourth time the annual games have been held. The Invictus Games are a multi-sport event specifically held for wounded or disabled veterans to participate in.
The Duke of Sussex has been touring Australia with his wife, Meghan, Duchess of Sussex, ahead of the start of the games on Saturday.
On Friday, Harry and Meghan started the day by meeting members of the OneWave surfer support group, which raises awareness of mental health issues.
Both Harry and Meghan beamed as they joined attendees for the daily Anti-Bad Vibes Circle at Bondi Beach, which the group usually follows up with yoga and surfing.
One member of the group told CNN affiliate Sky News the royals were “no different” to the rest of the group. “They (also) have their own amazing, individual, beautiful story. That’s what makes us all great, really,” he said.
A former British colony, Queen Elizabeth II is still Australia’s head of state despite repeated pushes to end the country’s ties to the UK monarchy.
Traces of republican sentiment have so far been obscured, however, as crowds of fans and well-wishers flock to meet the young royals, offering gifts of flowers and words of support for the pregnant duchess.
The royals will continue their two-week tour during the games, visiting Fiji and New Zealand, before returning to Australia for the closing ceremony on October 27.
This is the first time the Invictus Games have been held in Australia, after events in the United Kingdom, the United States and Canada. Eighteen different countries will be taking part in the 2018 Invictus Games, including Poland for the first time.
