Markle is scheduled to deliver a speech at the weekend’s gala dinner, described as a “fireside chat”, and pose for group photos with VIP guests.
“I have admired [Meghan] and what she has endured … and how she has demonstrated how a woman can be pushed down and she can still rise”, event organiser and Her Best Life podcast host Gemma O’Neill said.
O’Neill revealed that she and Markle share a mutual friend who connected them at Markle’s request.
Speaking on the latest episode of her podcast, O’Neill said she initially considered turning down the chance to interview Markle “because I felt like I didn’t deserve this”, but came around after “a lot of reflection”.
“She’s doing it because she really loves what our community is about, which is women trying to grow, try to be their best selves and trying to help other women.”
The Independent reported the Duke and Duchess will travel down under mid-next month to “take part in a number of private, business and philanthropic engagements”.
Their children, Prince Archie, 6, and Princess Lilibet, 4, are unlikely to join them.
The announcement comes only days after Markle said she was parting ways with Netflix and assuming full control of her homewares brand, As Ever.
“As it was always intended, Meghan will continue growing the brand and take it into its next chapter independently, and we look forward to celebrating how she continues to bring joy to households around the world”, a Netflix spokesperson said.
Markle and Harry signed a reported US$150 million ($242.5m) deal with the streaming platform in 2020.
The couple’s first offering, the documentary Harry and Meghan became one of Netflix’s most-viewed documentaries.
However, Markle’s docu-reality offering With Love, Meghan, widely panned by critics, was cancelled after only two seasons.
“With Love, Meghan is made with a great deal of love – in the sense that the greatest love of all is the one that a person has for herself,“ a review in Variety read.
