Prince Harry has landed in Sydney after his two-day visit to Singapore.
The prince is in the Australian city to launch the countdown to Invictus 2018 with the help of Prime Minister Malcolm Turnbull.
While at Admiralty House, Prince Harry gave insight as to what inspired his creation of the games.
“In February 2008, I was forced to leave Afghanistan. I had been serving as an army officer in the British army until my presence on the front line leaked out into the press,” Prince Harry started.
“I could no longer stay with my soldiers as it would have put them at greater risk. It was a decision over which I had no control but the guilt at having to leave my guys behind was hard to swallow as anyone who has served would understand.
“While we sat waiting to board, the coffin of a Danish soldier was loaded onto the plane, and three soldiers in induced comas, all three wrapped in plastic, some with missing limbs and tubes coming out everywhere.
“The sacrifices we ask our men and women to make came home to me in those moments.”
As Prince Harry tried to adjust to life at home he came to the conclusion that he needed to help servicemen and women do the same.
“Sport is what would make the difference. Sport would make these guys and girls rebuild their lives.
“As Australians know better than anyone, sport has an unparalleled ability to bring people together.”
Prince Harry went on to say: “I have no doubt that the Sydney public will make these games their own. They will witness the very best of human courage, defiance and spirit.”
He also made note of the London Terror Attack that took place over the weekend, paying tribute to one Australian who lost their life.
“Australians form an important and vibrant part of the fabric of life in London and we are reminded of that in good times and bad. And our hearts go out to the victims, their friends and families,” he said.
The 2018 Invictus Games will be the fourth instalment of the games. The first was held in London, then Orlando and in September of this year, Prince Harry is bringing the games to Toronto, Canada.
