All the best moments from day four of the Duke and Duchess of Sussex's royal tour

Today marked day four of the Duke and Duchess of Sussex‘s royal tour, with the pair returning to Sydney.

It was a jam-packed day full of activities for the royal couple, as they visited the likes of Bondi, the western suburbs of Sydney and the Sydney Harbour Bridge.

The final call of the day for the royal couple was included meeting with Bill Shorten, Leader of the Opposition at Admiralty House, followed by a meeting with Scott Morrison, Prime Minister of Australia, at Kirribilli House.

Prince Harry climbs the Sydney Harbour Bridge

Earlier on in the day, Prince Harry was taken to new heights in Sydney on day four of his royal tour with Meghan Markle.

The Duke of Sussex was suited up in a harness ready to take on the Sydney Harbour Bridge.

Unfortunately, Harry flew solo for this engagement on the royal tour as Meghan opted out of climbing the landmark, most likely because of her pregnancy.

Women who are pregnant can climb the bridge up until they hit the six month mark, but the Duchess of Sussex chose to stay back and probably have a well-deserved rest.

Harry, 34, wasn’t totally alone though as he was accompanied by Prime Minister Scott Morrison.

The pair were also accompanied by some Invictus Games competitors.

When Harry reached the top of the Harbour Bridge, he raised the Invictus Flag to celebrate the arrival of the games to Sydney.

Prince Harry and Meghan Markle’s surprise visit to Western Sydney school

Meghan have made a surprise visit to a Western Sydney school on day four of their royal tour.

The Duke and Duchess of Sussex spent time at Macarthur Girls High School, in Parramatta, NSW, to speak with students about issues including social justice and youth empowerment.

Accompanied by the Premier of NSW Gladys Berejiklian, the royal couple were treated to a dance performance on arrival, before meeting with several year 9 students, who are currently completing a project investigating issues of social justice and women and youth empowerment.

Meghan and Harry then moved into a classroom to speak to students involved with the NRL’s ‘In League in Harmony’ youth advocate program, which also aims to unite and inspire young people to be advocates for cohesion and inclusion in their communities.

The seven-week program is delivered in schools focusing on building a positive sense of self, setting goals, appreciating diversity, developing communication skills and working with others to achieve common goals.

Despite the busy schedule, Meghan had time to change outfits for the school visit.

She is now wearing a blue, $2,079 frock by Roksanda Ilincic and swapped her ponytail for a half-up, half-down hairstyle.

The Duke and Duchess of Sussex at Bondi Beach

Earlier this morning the Duchess of Sussex was handed a bunch of carrots from a royal fan as her and Prince Harry met locals on Bondi Beach in Sydney.

Thousands of people lined the sand, some having waited since 6am this morning for the chance to shake hands with the royal couple.

While there were plenty of flowers, and other gifts, it was a huge bunch of carrots that had Meghan smiling.

Hermione and Bridget were two lucky locals that got to meet the royals, having waited at Bondi since 6am this morning.

“We just met them it was absolutely unreal, I was lucky enough to get a handshake from Meghan and I even got a picture of that to keep as a memory,” she told Yahoo Lifestyle.

Prince Harry and Meghan arrived at Bondi Beach early this morning on a gloomy day in Sydney.

But that didn’t stop them getting comfortable and taking their shoes off on the sand as they met with a local surfing community group raising awareness for mental health and wellbeing, known as OneWave.

One Wave co-founders Grant Trebilco and Sam Schumacher wanted to use surfing as a way to help people talk to each other about mental health.

The Duke and Duchess took part in the ‘Fluro Friday’ session, where people share their experiences with mental health issues, and have the opportunity to interact with others while enjoying yoga and surfing.

Participants were dressed up for ‘Fluro Friday’, and even helped the Duke and Duchess get into the spirit by giving them leis to wear.

The pair spent over 20 minutes speaking with members of the group within the “Anti Bad Vibe Circle” where people of all ages discuss their experiences with mental health issues.

For many years The Duke has urged people to be more open about mental health challenges.

The Duke and Duchess of Sussex, along with The Duke and Duchess of Cambridge, have lead a UK mental health initiative called Heads Together, which combines a campaign to tackle stigma and change the conversation on mental health.

Founder Grant Trebilco said it was “unreal” to have the Duke and Duchess take part in their circle.

“They are making mental health visible,” Grant told Sunrise. “To have them here and sharing real stories it just shows that mental health doesn’t discriminate.

“I was amazed [at how long he stayed here]. He is such a good bloke.

“In the circle he said that reaching out for help is not a weakness it’s a strength. Harry also spoke about Heads Together, their charity in the UK, and Meghan spoke about how she practices yoga every day that yoga is her escape.”

After speaking with the group, the couple were also gifted a surfboard, and were shown how to wax it.

Harry and Meghan are dressed casually for their day of activities across wider Sydney, Harry wearing brown trousers and a pale blue shirt.

Meghan is looking summer-chic wearing a $1615 striped maxi dress with spaghetti straps by Martin Grant – the same Aussie designer of her favourite coat she has worn on the tour already.

Harry and Meghan have been in the country since Monday, for a 16-day stint in Australia.

During that time, they will take in all the sights of Australia, before heading to Fiji, Tonga and New Zealand, meeting with locals and carrying out engagements at the Invictus Games in Sydney.

Kensington Palace has revealed that their trip “will focus on youth leadership, and projects being undertaken by young people to address the social, economic, and environmental challenges of the region”.

Meghan Markle is pregnant

Just hours after they arrived in Australia on Monday, the royal pair announced they were expecting their first child together.

“Their Royal Highnesses The Duke and Duchess of Sussex are very pleased to announce that The Duchess of Sussex is expecting a baby in the Spring of 2019,” the palace said in statement on Twitter.

“Their Royal Highnesses have appreciated all of the support they have received from people around the world since their wedding in May and are delighted to be able to share this happy news with the public.”
