Kensington Palace says Prince Harry and his wife the Duchess of Sussex are expecting a child in autumn next year.
The palace says the couple has "appreciated all of the support they have received from people around the world since their wedding in May and are delighted to be able to share this happy news with the public."
The announcement Monday comes as Harry and the former Meghan Markle arrived in Sydney at the start of a 16-day visit to Australia, Fiji, Tonga and New Zealand.
The trip officially begins on Tuesday and will see the couple watch the Invictus Games, visit a Sydney zoo and visit the rural Flying Doctor service.
Australian politician Pauline Hanson has declared "anti-white" racism is on the rise, unsuccessfully moving a motion in federal parliament saying "it's OK to be white".
The One Nation leader said anyone who watched the news or social media could see increased attacks on western civilisation and the prevalence of anti-white racism.
"It is indeed OK to be white. Such a simple sentence should go without saying but I suspect many members in this place would struggle to say it," she told parliament.
"People have a right to be proud of their cultural background whether they are black, white or brindle."
The motion was defeated 31-28 despite the support of government senators.
Crossbench senator Derryn Hinch savaged Senator Hanson, saying she was locked in a race to the bottom of the sewer with Katter's Australian Party member Fraser Anning.
"It could have been written on a piece of toilet paper," Senator Hinch said of the motion.
"This sort of racism is not only wrong, it could be dangerous."
Greens leader Richard Di Natale also had a crack at former One Nation senator Anning and Senator Hanson.
"The reality is this 'it's OK to be white' slogan has got a long history in the white supremacist movement where both these clowns get most of their material from," Senator Di Natale said.
Donald Trump, who recently said he and Kim Jong Un "fell in love" has bristled in a US TV interview when told the North Korean leader presides over "a cruel kingdom of repression".
Mr Trump told supporters earlier this month at a political rally he and Kim "fell in love".
"He wrote me beautiful letters. And they’re great letters. We fell in love," he said.
Veteran CBS 60 Minutes journalist Leslie Stahl read Mr Trump what she described as Mr Kim's "resume".
"He presides over a cruel kingdom of repression. Gulags, starvation, reports that he had his half-brother assassinated, slave labour, executions - this is a guy you love?" she asked.
Mr Trump responded: "I know all these things. I mean, I’m not a baby. I know these things."
He said his "love" comment was a a figure of speech.
"Look. Look. I like, I get along with him, OK?" he said.
"Let it be whatever it is. I get along with him really well. I have a good energy with him, I have a good chemistry with him. Look at the horrible threats that were made. No more threats. No more threats."
Mr Trump said that the day before he came into power, we were going to war with North Korea. I think it was going to end up in war".
"Now you don’t hear that. You don’t hear any talk of it. And he [Kim Jong Un] doesn't want to go to war, and we don't want to go to war, and he understands denuclearisation and he's agreed to it," he added.
"I do trust him. I trust him. That doesn’t mean I can’t be proven wrong." the President said.
It's obvious that three men accused of plotting a Christmas Day Melbourne terror attack wanted to "wage violent jihad" against non-believers, a jury at the Supreme Court of Victoria has been told.
Their plans were well and truly on foot by late October 2016 and in the following two months they bought bomb-making materials and machetes and scouted CBD locations, crown prosecutor Nick Papas QC says.
After weeks of evidence, the Crown is summing up its case against Hamza Abbas, 23, his cousin Abdullah Chaarani, 27, and Ahmed Mohamed, 25, who all deny knowledge and involvement in planning an attack on Federation Square two years ago.
Hamza's 24-year-old brother Ibrahim Abbas has already pleaded guilty to preparing for the attack and gave evidence he was a leader trying to recruit others for his cause.
But Mr Papas urged jurors today to reject that suggestion and find Ibrahim was not a leader, but a co-conspirator in a plan to "wage violent jihad against those they believed to be disbelievers".
He replayed CCTV of the foursome meeting at Federation Square days before their alleged attack was to take place.
An extremist video found on Chaarani's phone showed pictures of Federation Square, St Paul's Cathedral and the Yarra River and called for watchers to "come to martyrdom".
"The Crown says they're talking about this as a great place to cause lots of mayhem and injuries, lots of innocent people to be killed, the more the better," Mr Papas said of the CCTV.
Ibrahim described the gathering as a spontaneous drive to the city to get ice cream, during which he suggested the location might be good for an attack.
But Mr Papas said that contention was "ridiculous", and even Mohamed's wife had sent him a text that afternoon saying "I don't appreciate how secretive you're being".
Mohamed and Chaarani are accused of working on plans from October 2016, when it's alleged Mohamed saved a link to the Al Qaeda magazine article "How to make a bomb in the kitchen of your mom" and that he and Chaarani searched for information on sparkler explosives.
Mohamed and Ibrahim also purchased materials including light globes, pipes and Ramset cartridges, the prosecution argues.
It's alleged Hamza became involved from December, but did so with full knowledge of the sourcing of materials and other preparations.
He joined Mohamed, Chaarani and Ibrahim on the final of three trips to Clonbinane, when it's claimed they tested a bomb in a state forest.
When that failed it's alleged they moved to a new bomb-making method involving hydrogen peroxide, which Hamza and Mohamed were seen purchasing on CCTV.
"The Crown says (they thought) 'one way of setting off a bomb has failed, let's try the other way'," Mr Papas said.
The Crown closing continues.
