Due to the mutual interest in approaching each other, the relationship between William and Princess Alexandrine heated up rapidly in a short period of time.
Seeing that it was about time, Queen Mary formally represented the Australasian Royal Family in proposing a matrimonial alliance to the Danish royal family, who gladly accepted.
On April 27, 1929, the Australasian Royal Family and the Danish royal family officially announced the engagement of William and Alexandrine and publicly set their engagement date for later this year, around October.
Almost simultaneously, the governments of both countries offered their congratulations on the royal union, with the Australasian Government also publicly inviting the Danish government for a diplomatic visit to discuss further cooperation.
The Danish government naturally accepted with pleasure. An invitation from a superpower is not something any country would refuse unless it was a declaration of war.
