Mary Donaldson's first job as Denmark's newest princess will be to produce a half-Australian heir to one of the oldest monarchies in the world, royal watchers say.
Ms. Donaldson, the first Australian to become a European queen, has already won a place in Danish hearts by barely saying a word.
To stay there she must be a diligent member of a scandal-free royal family universally loved by the Danes.
According to Trine Larsen, a royal reporter for Denmark's biggest selling tabloid newspaper Ekstra Bladet, Ms. Donaldson must speak Danish fluently without an Australian accent, she must show she loves Frederik and is not a gold digger, and she must be "nice, discreet and not a big spender".
She has to live up to Frederik's sister-in-law, Princess Alexandra, who "hasn't put a foot wrong" since the Hong Kong-born half Chinese came to Denmark to marry Prince Joachim eight years ago.
But, "first off, her most important job is to have children", Larsen said.
"We have one of the oldest monarchies in the world and we want it to keep going."
Ms. Donaldson, 31, has already had fertility tests to ensure she can have children and has signed an agreement that in the event of a divorce, Frederik retains custody of all children, who will remain in Denmark.
She will also have to give up her Australian citizenship.
In return, the Danes have welcomed her warmly.
But can a woman who grew up in suburban Taroona in Hobart, worked in Sydney, met a prince in a pub, and then moved to Copenhagen, live up to Denmark's high expectations of its monarchy?
"That is the key question because none of us know her," Larsen said.
"Up to now, we have never seen her in person; she has said hardly a word in the two years she has lived here.
"But the prince is so beloved he could come up with anyone and people would accept her. The people of Denmark say if he is in love with her, that's all right."
Well, she was differently fertile but discreet and not a big spender and a golddigger yeah that has already been discovered a long time from us here at the royal dish. I guess the danish people are still drinking the cool-aid wait till marge dies then shit will hit the fan and they will then realize that Fred is not capable to be ahead of the state and neither is his wife then watch a revolution take place when the danish people dethrone them that if they have the balls.
