According to celebrity PR specialist Kayley Cornelius, the decision indicates a wider initiative to reshape Markle's public profile and career trajectory, which suffered following Markle's Australia tour 'blunder.'
"Meghan's latest move on MasterChef feel far from random or one-off appearances, there's a clear strategy at play here and it very much points to a more permanent return to the world of mainstream celebrity being front of mind.
The PR expert also suggested the MasterChef Australia appearance might serve as a trial run for a more substantial return to television and the world of celebrity.
"If this return is successful, and builds that connection with viewers, it puts her in a much stronger position with casting producers. From there, a return to bigger on-screen roles isn't out of the question, and with the right momentum, it could mark the start of a new chapter that reshapes both her public image and her career trajectory."
Kinsey Schofield, host of YouTube's Kinsey Schofield Unfiltered, claimed the visit has sparked unease amongst royal insiders.
"The palace is unhappy about these rent-a-royal tours because it blatantly disregards the late queen's very specific instruction that there can be no half-in, half-out for the Sussexes," Schofield told Fox News Digital.
"All they are doing in Australia is monetizing their titles and clinging to royal relevance, even though most of Prince Harry's family refuse to take his phone calls," Schofield claimed.
