Princess Isabella of Denmark is heading into the military.
The 18-year-old daughter of King Frederik and Queen Mary, our very own Australian-born queen, will begin her military service in August.

Isabella is second in line to the Danish throne behind her older brother, Crown Prince Christian, 20.
She will serve at the Guard Hussar Regiment in Slagelse, the very same regiment where Christian completed his own military service.
“Her Royal Highness Princess Isabella will serve her military service at the Guard Hussar Regiment in Slagelse after completing her high school diploma. The Princess will be among the first to serve 11 months of military service,” the Danish royals confirmed on March 31.
The timing is significant as Denmark made history in July 2025 by extending military conscription to women for the first time.

Isabella, who turns 19 on April 21, will be among the very first young women to complete the expanded 11-month program.
Previously, conscription only applied to physically fit men over 18. The new system includes women and has extended the service period from four months to 11 months.
The palace shared a carousel of photos to Instagram alongside the announcement, closing with a sweet snap of Isabella visiting Christian at the Guard Hussar Barracks in Slagelse in spring 2025.

The news comes after Queen Mary delivered an unexpected speech to conclude her and King Frederik’s Australian royal tour last month.
The Danish royal returned to her native Hobart, where she was born, for the final stop on the couple’s tour Down Under.
Frederik was reportedly due to give the final speech on their tour, but Mary stepped up to the lectern to issue her own deeply personal message.
After arriving at Government House, Mary emotionally thanked Australia for their support over the years as she concluded her first tour of the country since becoming the Danish queen.

“I’m a bit lost for words, I’m a bit overwhelmed,” she said as her voice broke with emotion, according to 9Honey.
“But thank you, everyone, for being here. Last night [Wednesday], I ended a speech in Melbourne, saying how privileged I am that my roots are grounded both in Australia and Denmark.
“But they do go a little bit deeper in Tasmania.
“There really isn’t a more special place to end what has been a unique, rewarding, moving, exciting, curious tour – state visit – to Australia from Denmark.”
