After a big Friday night as guests of honour at the Australian Geographic Society awards in Sydney, Harry and Meghan were happy to sit among the crowd to watch the Invictus Games’ basketball final.

Sneaking in just after 2pm on Saturday, the Duke and Duchess of Sussex made their way to seats in the back row among a group of men in army greens, avoiding politicians and celebrities.

They didn’t join Prime Minister Scott Morrison, Defence Minister Christopher Pyne or ambassadors David Beckham and Ian Thorpe at Olympic Park’s Quay Centre’s reserved area to watch the USA take on the Netherlands in the wheelchair basketball final.

Beckham, who also attended the athletics on Friday night, was accompanied by son, Romeo, 16.

Meghan wore a maroon wrap top by Australian designer Scanlan Theodore and black jeans, with her hair slicked back, while Harry selected a black branded Invictus polo shirt.

The royal couple handed out medals at the end of the match after US won 29 -17, jumping to their feet as the final whistle blew. They will then  attend the closing ceremony of the games later on Saturday night.

Harry and Meghan flew back into Sydney on Friday afternoon after visiting Fiji and Tonga and spent barely an hour at the awards, where they were given another soft toy – a wombat – to add to their collection of presents for the baby they are expecting next year.

Meghan wowed in her black and white Oscar de la Renta gown with tulle skirt and laser-cut bird motif as the royal couple were whisked in after guests had enjoyed their main course.

Harry had a brief chance to catch up with Eric Philips, an Australian polar explorer who helped the duke and an international group of wounded soldiers ski to the South Pole in 2013, before accepting an award on behalf of the Queen.

It is the couple’s final day in Australia before they head to New Zealand on Sunday.
