The royal couple have been on an epic 16-day tour which has so far seen them visit Australia, Fiji and Tonga.
Their flight touched down safely at Sydney airport but not before a mid air drama that saw the plane's captain abort the landing.
"Minor drama as our @Qantas charter plane - also carrying Harry and Meghan - had to pull up seconds from landing in Sydney because of another aircraft on the runway," Daily Mail reporter Rebecca English tweeted.
"Pilot said we were too close. What’s known as a missed approach. We had to circle and try again."
"Our plane has aborted landing," wrote royal commentator Omid Scobie on Twitter.
"Captain calling it a “missed approach” - there was another plane on the runway that was leaving too slowly. Back up we go."
