King Frederik and Queen Mary began their final day in Melbourne as part of a whistlestop state visit, attending an event focused on supporting commercial and institutional cooperation between the nations for a green transition.
The king delivered a speech to an audience of business leaders, which also included Australia's Climate Change and Energy Minister Chris Bowen.
The monarchs then turned their attention to health collaborations, visiting a stem cell innovation research event at the Murdoch Children's Research Institute and Royal Children's Hospital, where they toured the site and discussed the latest advances in medical technology.
A crowd of excited staff, parents and children had gathered inside the building, hoping to catch a glimpse of the Australia-born royal.
Prime Minister Anthony Albanese, who hosted the couple in Canberra and will meet them again in Hobart, said they were delightful, humble, engaging and very interested in Australia, particularly Tasmania where the queen is from.
"It is extraordinary - the whole story, and I think it's one that appeals," he told reporters in Burnie, Tasmania.
"At a time where there is a lot of negativity in the world, isn't it wonderful that we have this relationship and story which we should celebrate?"
The royals are in Australia for a six-day visit, the first since Frederik became king in 2024.
On Tuesday, the royals attended an official reception at Government House, toured sustainable and renewable energy developments and had a kick of a footy at the MCG.
The pair had met with Mr Albanese and other dignitaries in Canberra and also visited Uluru.
The royals are aiming for their visit will deepen trade ties between Queen Mary's adopted and home nations, with a focus on clean energy.
On their final stop is Mary's home state of Tasmania, where they will spend time with the Queen's relatives, including her elderly father John Donaldson.
