Prince Harry and Meghan Markle will be heading to Australia next year.

Prince Harry and the "Suits" actress are slated to have an Australian tour in 2018 just months after their wedding. According to Herald Sun (via News.com.au), the pair will be flying to Sydney for the 2018 Invictus Games from Oct. 20 to 27.

Prince Harry founded the event as an Olympics for injured servicemen and women. The upcoming tour in Australia will be Markle's first major tour overseas as a royal wife.

Back in September, the 2017 Invictus Games was held in Toronto. During the event, Prince Harry and Markle made their first public appearance as a couple.

Markle also invited her mom, Doria Radlan, during the closing ceremony. Prince Harry was spotted hanging out with the mother and daughter duo after giving a speech. The trio looked happy and comfortable.

In addition, during his stay in Toronto, Prince Harry took the time to visit the set of USA Network's hit legal drama TV series "Suits." His fiancée returned the favor by giving Prince Harry a tour on set and by introducing him to the crew.

Prince Harry and Markle are set to exchange vows in May, five months before the 2018 Invictus Games. Their wedding ceremony will be held in St. George's Chapel at Windsor Castle. The couple's nuptials will be simpler compared to Prince William and Kate Middleton's royal wedding in 2011.

The couple opted for a smaller church and may skip some of the royal wedding traditions like the balcony kiss and the horse-drawn carriage. In addition, Prince Harry and Markle are expected to have more celebrity and fewer dignitary guests.

A number of royal experts already expect a simple wedding for Prince Harry and Markle because the latter is a divorcee. "Meghan Markle has already been married, so I believe they would have a service of blessing," Hugo Vickers said. "You wouldn't necessarily have a big grand ceremony, and it would be more like Charles and Camilla," Scott Peterson added.

"Meghan is, after all, a divorcee, so it would probably be a registry office ceremony with a church blessing afterwards," royal biographer Penny Junor added.

Meanwhile, another source revealed that Prince Harry prefers it this way because he wants his wedding with Markle to be private and intimate. "I can see him wanting to get married at St George's Chapel at Windsor Castle. It would stop it from turning into a total media circus and give the day a sense of privacy that Harry so badly craves," the insider said.
