Prince Harry has paid tribute to the thousands of Australians who lost their lives in battle during a visit to the Anzac Memorial in Sydney.
Harry and wife Meghan were greeted by a small crowd of well wishers as they arrived at the memorial's new entrance on the edge of the city's Hyde Park on Saturday morning.
The royal couple toured the memorial's new underground hall of service pausing to look at the huge display of soil samples taken from the 1701 towns across NSW where thousands of young men and women enlisted for World War One.
Another display of 100 soil samples, taken from battlefields where thousands of NSW troops have fought around the world since the 1856 Colonial Wars through to Iraq and Afghanistan, ringed the floor.
The displays feature as a highlight of the recently renovated memorial, which was never fully completed in line with its original architectural plans when opened in 1934 because of the financial hardships of the Great Depression
For Harry, being able to visit and officially open the newly-renovated sections represented a royal step back in time as his great, great uncle and namesake Prince Henry, Duke of Gloucester - who later went on to become Australia's 11th Governor General - opened the building in 1934.
The memorial contains the original wreath of red flowers laid by the Duke, fixed in its faded glory in a glass case outside the memorial's hall of memory.
NSW Governor David Hurley and his wife Linda escorted former British army officer Harry and Meghan around the building, where they paused by the statue of sacrifice and visited the hall of memory, with its towering ceiling dotted with gold stars paying tribute to the thousands of NSW men and women killers in WWI.
Meghan chose a sombre black dress with gold buttons by British designer Emilia Wickstead and hat by Philip Treacy to wear to the memorial.
Harry donned his Blues and Royals tropical dress uniform featuring military medals from his decade long service with the British Army.
Watched by NSW Premier Gladys Berejiklian and Prime Minister Scott Morrison, Harry and Meghan laid a colourful wreath of Australian native flowers at the memorial's front step.
Harry saluted as the Last Post rang out across Hyde Park before the crowd of about 200 dignitaries and invited guests paused for a minute's silence.
He then joined Ms Berejiklian on the steps to unveil a plaque for the memorial's extension before three RAAF jets flew over.
The premier said it was poignant the $40 million extension had been completed just weeks before the centenary of the end of WWI next month.
She said the "magestic memorial" commemorated "all those who fought for our nation and made the ultimate sacrifice" and was a unique "place of reflection far from the horrors of war".
With the official proceedings over, Harry and Meghan prepared to make their exit but stopped for a quick chat with two young indigenous schoolgirls in the front row.
Twins Sienna and Krystal Dawson, 9, presented the royal couple with a colourful floral painting and silver medallion from their school, Beverly Hills Public School.
The girls had been part of the indigenous welcome ceremony by members of Koomurri that greeted the royals on their arrival
"They came over and said 'hi, what's your name," Sienna said.
"I said Sienna and she said Krystal and I gave them the things I had and Kyrstal did too."
Mum Connie Dawson said the girls had been nervous.
"And I was overwhelmed for them as a parent," she laughed.
The royal couple were scheduled to end day five of their Australia tour at the opening ceremony of the Invictus Games at the Opera House.
