New details of Prince Harry and Meghan Markle's two-week royal tour were revealed Monday.

The Duke and Duchess of Sussex will tour Australia, New Zealand, Fiji and Tonga from Oct. 16-31 on behalf of Queen Elizabeth and the Foreign and Commonwealth Office, Kensington Palace said.

The couple's stops in Sydney, Melbourne and Fraser Island, as well as Auckland and Wellington in New Zealand, will make up the bulk of their itinerary.
