Prince Harry and
Meghan Markle have joined the Australian Prime Minister at a
London reception ahead of the
Invictus Games in
Sydney later this year.
Harry and his bride-to-be will meet servicemen and women from both Britain and Australia, some of whom have previously competed in the international sporting event.
The couple will also learn more about preparations for this year's games at the reception hosted by
Malcolm Turnbull and his wife Lucy at Australia House on Saturday.
More than 500 competitors - made up of sick and injured military and veterans - from 18 nations are expected to compete at the Invictus Games in Sydney between October 20 and 27.
It is expected Harry, who is patron of the Invictus Games Foundation which oversees the delivery of the tournament, will travel to Australia for the event with Ms Markle, who will by then be his wife.
When Toronto hosted the Paralympic-style event last year the former Suits star, who at the time was living and working in the city, attended the opening and closing ceremonies and visited competitors with Harry.
The trip to Sydney is also likely to see the couple embark on their Commonwealth duties, meeting young Australians to discuss issues close to their hearts after Prince Harry was appointed youth ambassador.
Servicemen and women at the Invictus launch praised Prince Harry for changing lives ahead of this year's Games in Sydney.
Gareth Paterson, from Newcastle, who is leaving the army after 24 years' service, said: "You can't really fault the guy, he puts in so much effort.
"He genuinely cares about everyone he meets and remembers who people are."
Mr Paterson, who suffers from an autoimmune disease which fuses the spine, competed at the Orlando and Toronto Invictus Games, winning three gold medals in archery.
Jo Hursey, 42, from Herefordshire, who knows Harry from her 23 years in the army, said: "I don't think he realises how many lives he's changed.
"He's changed mine for the better."
