Australian Governor-General welcomes Royal Birth

Statement from Her Majesty's Australian Prime Minister, The Hon. Kevin Rudd
The Prime Minister today congratulated the Duke and Duchess of Cambridge on the birth of their first child, a son.
On behalf of all Australians, Therese and I extend our warmest regards to the new parents, Prince William, Duke of Cambridge and Catherine, Duchess of Cambridge.
Prince William holds a special place in the hearts of many Australians. Some of us remember his first visit to this country as a 9 month old baby more than 30 years ago with his mother Diana and father Charles.
In more recent times, Prince William demonstrated deep compassion when he met with families in Victoria who had lost everything during the Black Saturday bushfires of February 2009.
We share in the joy of the Royal Family, particularly Prince Charles on the birth of his grandson and Queen Elizabeth II on the birth of her great grandchild.
This is a happy day for our close friends in Britain and the Commonwealth.
Statement from the Leader of Her Majesty's Loyal Australian Opposition, The Hon. Tony Abbott Margie and I join all Australians in extending to the Duke and Duchess of Cambridge congratulations and best wishes on the birth of their son.
This would be the happiest day in their lives and all Australians share their joy.
While there will come a time to contemplate the constitutional duties that await the young Prince, today we simply welcome a baby boy into the world and share the joy of this young family.
I am sure that over the course of his life, the Prince will, like the rest of his family, develop a deep affection for our country, as we already have for him.
