Australia launched a special stamp to commemorate Britain's pending royal nuptials on Monday, with a local and international issue featuring Prince William and his bride Kate Middleton.
Australia Post said it was "delighted" to celebrate the April 29 wedding with a special edition stamp showing a portrait of the couple after their engagement was announced.
"We trust this special stamp issue provides collectors and the public with a memento to mark this happy and historic event," said Australia Post chief Ahmed Fahour.
Formerly a British colony where Queen Elizabeth II is still head of state, Australia has already issued a special 50 cent coin to commemorate the royal wedding, designed by the Queen's own goldsmith and jeweller.
Collectors can also buy an official Royal Wedding coin with the couple's engagement photo in colour against a detailed sketch of Westminster Abbey, where they will wed.
The royal wedding will be keenly watched in Australia, where Prince William charmed thousands with a recent tour to flood-affected zones but which also harbours a keen republican sentiment.
