Meghan Markle and Prince Harry are yet to set foot in London following the announcement that the duchess is pregnant.
The pair revealed they are to become parents for the fist time on Monday, just as they touched down in Australia.
Harry and Meghan are in Australia for a 16-day tour of Australia, New Zealand, Fiji and Tonga.
So when will they be back in London?
The Duke and Duchess of Sussex kicked off their first overseas tour as a married couple in Sydney on Tuesday 16 October, with it finishing in New Zealand on 31 October.
Given the flight time is around 24 hours from NZ to London, it’s unlikely they;ll be pictured having arrived home until Monday 1 or Tuesday 2 November.
Their tour is a little shorter than the Duke and Duchess Of Cambridge’s tour Down Under. They visited Australia and New Zealand in April 2014, spending 18 days away. It was their first visit their as a married couple.
And when Harry’s parents Prince Charles and Diana, Princess of Wales, made the same voyage in 1983, they were away for more than double this length of time, spending 41 days overseas.

No doubt they’ll be looking forward to putting their feet up and enjoying a roast chicken dinner when they’re home, given they will get very little time alone during their tour.
They’re doing 76 engagements in 16 days and while royal tours used to last for months on end, they now tend to be much shorter with at least four engagements per day.
With flights and car journeys in-between the engagements, Harry and Meghan will get very little alone time. They will be granted one morning or one afternoon off work to recharge, however.

The Invictus Games will be a poignant event for the couple to visit, given the Invictus Games in Toronto, Canada, in 2017 are where they made their first public appearance together.
Prince Harry founded the games, which are for sick and wounded military personnel, in 2014.
