The Duchess of Sussex will make an appearance as a guest judge on a new season of hit Australian television show MasterChef Australia.

Meghan filmed in the episode in Melbourne on Wednesday, according to broadcaster Network Ten. The show’s eighteenth season is set to air on April 19.

Meghan, together with Prince Harry, are currently on the second day of a four-day tour of Australia, which will see them combine visits to charitable causes alongside money-making events.

The couple, no longer working royals, are visiting in a private capacity. It is their first time in Australia since 2018, as part of an intense tour just a few months after their marriage.

In a separate event on Wednesday, Prince Harry joined players from an Australian Rules football team for a lesson in how to play a game and visited the Australian War Memorial in Canberra.

The couple have more scheduled engagements in Melbourne on Thursday before traveling to Sydney.

On Tuesday, the duo visited the Royal Children’s Hospital in Melbourne where hundreds had gathered at the foyer to catch a glimpse of the couple.

Meghan also visited a women’s refuge in Melbourne, where she served plates of frittata to people at the centre.

Prince Harry is due to give a keynote speech at the InterEdge Psychosocial Safety Summit in Melbourne later this week, where tickets to attend cost from around A$1,000 ($713; £526) up to A$2,400. All ticket proceeds will go to the charity Lifeline.

The BBC has asked organisers whether the duke is receiving a fee.

On Saturday, the Duchess will hold an “in-person conversation” at a women’s only weekend retreat in Sydney.

Guests are paying up to A$3,199 to attend a “girls’ weekend”, with a VIP package including the opportunity to get a group table photograph with Meghan.

It is not known what the duchess will be paid for her involvement in the event, which has not sold out and is still advertising a “handful of additional rooms”.

Meghan’s appearance comes off the back of her own lifestyle and cookery show, With Love, Meghan, which seeds her share cooking and hosting tips with friends and guests.

There are also suggestions that Australia is being considered as a market for Meghan’s As Ever lifestyle brand – which was featured prominently in the Netflix series.

Last year, the company registered trademarks in 12 different product categories in Australia, according to a government intellectual property database.
