PA Wire/PA Images Australia's Governor General Peter Cosgrove gives the Duke and Duchess of Sussex a toy kangaroo - with a baby - at Admiralty House in Sydney on the first day of the royal couple's visit to Australia.
The former Suits star told the 14-year-olds she used to "take out the trash" and it humbled her and made her who she is today.
The father-to-be also gushed about the couple's exciting baby news, which was announced hours after he and wife Meghan Markle landed in Australia earlier in the week.
The first event of the Invictus Games - the Jaguar Land Rover Driving Challenge - got underway in the afternoon, with the Duke and Duchess on hand to watch.
Kensington Palace said her schedule was being "cut back" after a busy schedule.

Harry and Morrison smiled as the black, grey and yellow flag of the Invictus Games was hoisted on the Sydney landmark on the eve of the worldwide paralympic event, founded by Harry for military personnel wounded in action, which runs until October 27.
Prince Harry kicked off the fourth annual Invictus Games on Saturday by telling veterans to "allow the example of service and determination you will see, to change something big or small in your own lives". "You are the optimistic generation". According to Entertainment Tonight, while aboard the tram, a 12-year-old student by the name of Charlie Wolf asked the newly pregnant couple if they had thought of any names for their unborn child.
Harry saluted as the Last Post rang out across Hyde Park, while Meghan, in a long black dress by New Zealand designer Emilia Wickstead, stood beside him.
Harry and wife Meghan also enjoyed the entertainment of the night, as they sat front and centre to the stage.
