The Duke and Duchess of Sussex have now wrapped up their four-day Australian tour, during which one royal expert believes she spotted a revealing moment from a word Prince Harry repeatedly used.

Harry and Meghan Markle spent the final day of their trip paying tribute to the Bondi Beach terror attack heroes, meeting with surf club members who assisted when a gunman claimed the lives of 15 people at the Hanukkah event in December.

Yet it was in Melbourne where Victoria Ward, deputy royal editor of The Telegraph, observed just how deeply Harry felt compelled to serve others.

In 2021, the Queen confirmed that Harry and his wife would not "continue with the responsibilities and duties that come with a life of public service".

The Sussexes, however, responded with: "We can all live a life of service. Service is universal."

This particular word resurfaced throughout the Australian visit, with Victoria remarking: "It was telling, I thought, that the word came up again yesterday.

"During a short QandA on stage at the InterEdge leadership summit, the Duke described how, following the death of his mother, he decided he did not want this job."

Harry told the summit: "I don't want this role, wherever this is headed. I don't like it. It killed my mum. I was very much against it."

Nevertheless, Victoria noted that he ultimately "realised that he could use his platform to try to make a difference in the world."

Harry said: "What would my mum want me to do? That really changed my perspective.

"I realised well, actually, helping other people is also helping me. Service, for me, is a cure in itself."

Beyond Sydney and Melbourne, the couple also made a stop in Canberra as part of their tour.

It marked their first trip to Australia since announcing in 2018 that the country would play host to the Invictus Games.

In Melbourne, the Duchess urged people to remain "strong" in the face of social media bullying, during a discussion with students at Swinburne University of Technology on the subjects of mental health and social media.

She said: "And I can speak to that really personally, which is why I like to listen, because it rings true for me in a very real way.

"For now, 10 years, every day for 10 years, I have been bullied and attacked. And I was the most trolled person in the entire world."

She added: "I'm still here."

Following a meeting with first responders from the Bondi Surf Bathers' Life Saving club, Elon Zizer, 40, who survived the shooting, remarked: "It's very special. It makes us feel heard." Jessica Chapnik Kahn, who shielded her five-year-old daughter during the harrowing incident, described it as an honour to meet them.

On their final evening in Sydney, Harry and Meghan attended a rugby match between the New South Wales Waratahs and Moana Pasifika. They were guests of Australian Rugby Union CEO Phil Waugh, who was seated beside them, and it was Harry's first rugby match in Sydney since witnessing England claim the World Cup in 2003.
