The Duke and Duchess of Sussex have arrived in Australia for a four-day tour which will see them combine visits to charitable causes alongside private, money-making engagements.

The couple - no longer working royals and visiting in a private capacity - will meet patients and medics at a children's hospital, military veterans and their families, and survivors of family violence.

The schedule also reflects the commercial aspect of the trip, with Prince Harry due to give a keynote speech at a summit where tickets cost up to A$2,400 (£1,260) per person.

Meghan will hold an in-person conversation at a women-only girls weekend in Sydney hosted by the producers of the Her Best Life podcast.

It is unclear how much Prince Harry and Meghan are being paid for the commercial events.

The couple landed at Melbourne airport around 06:30 on Tuesday (21:30 BST Monday) on a commercial Qantas flight from Los Angeles.

This is Harry and Meghan's first visit to Australia since 2018, which was an intense tour just months after their marriage.

Unlike their previous trips where large crowds gathered, this time there are no public meet-and-greet events planned.

After stepping down as working royals in January 2020 and giving up their HRH titles, Prince Harry and Meghan are now visiting as private citizens, stating that the trip is privately funded. However, questions remain about whether Australian taxpayers are covering the cost of security during their visit.

The visit will take place in Melbourne, Canberra, and Sydney, focusing on charitable causes, while also allowing the couple to profit from various events.

As part of the tour, Prince Harry is set to speak at the InterEdge Psychosocial Safety Summit, with ticket prices ranging from A$1,000 to A$2,400, and some proceeds going to the charity Lifeline.

Meghan's girls weekend event in Sydney charges guests up to A$3,199, which includes opportunities for intimate interactions with the Duchess. It remains uncertain how much she will earn for her participation.

They have chosen not to engage in public events to minimize disruption, but security forces in Victoria and New South Wales will ensure public safety during their stay.

This visit comes amid scrutiny regarding security provisions for Prince Harry, especially after recent legal challenges surrounding his personal safety.
