Sight in waiting crowd stops Queen Mary and King Frederik X of Denmark in their tracks during packed schedule

It was a busy day for Australia's own Queen Mary of Denmark and her husband, King Frederik X, who had back-to-back royal engagements scheduled in Copenhagen.

That didn't deter the duo, however, from stopping and smelling the roses – especially when the bouquets were given to them by children.

Mary, 52, and Frederik, 55, were photographed multiple times pausing and sharing sweet moments with young royal fans waiting in crowds as the royal couple dashed from the University of Copenhagen to Copenhagen Harbour and royal couple dashed from the University of Copenhagen to Copenhagen Harbour.

Tasmanian-born Mary spent the morning presenting scholarships to two Australian exchange students at the University of Copenhagen, as she does annually as part of the Crown Princess Mary Scholarship program.

A young fan – Petra Bruun Funch – was waiting outside the event for Mary, who stopped and kneeled down to speak with her as Bruun Funch handed her a bunch of flowers.

Next for Mary was an outfit change and a trip to Copenhagen Harbour, where she and Frederik boarded the Royal Yacht Dannebrog for a brief sail – and another outfit change – ahead of their first summer sailing trip as monarchs in August.

In a video shared by the Danish Royal House on social media, Mary could be seen embracing Frederik, who was wearing his formal navy uniform.

"Denmark showed itself from its beautiful side, when the Royal Ship Dannebrog circled Kronborg Castle in Helsingør earlier today," the Danish Royal House wrote on Instagram alongside the footage.

"For 92 years, the Royal Ship Dannebrog has served as the official and private residence for Christian X, Frederick IX and Her Majesty Queen Margrethe II."

The message concluded: "Today, Their Majesties The King and Queen continued this tradition as they began their first sailing season as a royal couple at noon."

After the royal couple's brief sea sojourn, they disembarked and travelled to Fredensborg Palace, which is located on the eastern shore of Lake Esrum in Fredensborg on the island of Zealand in Denmark.

There, crowds of royal fans had gathered to greet the King and Queen, including several children, whom Mary and Frederik were all to happy to greet.

In fact, the King was pictured multiple times crouching down to speak with his young fans, a majority of which had Danish flags to wave.

Mary and Frederik's series of public appearances – held on Thursday in Denmark but overnight in Australia – came days before the couple are set to travel to Sweden and Norway, for their first state visits as monarchs.

It comes months after they ascended the throne in January, following Margrethe's historic abdication.
