King Charles III travels to Australia for first royal visit since cancer diagnosis

King Charles III and Queen Camilla arrived in Sydney on Friday for the first Australian visit by a reigning monarch in more than a decade, a trip that has rekindled debate about the nation's constitutional links to Britain.

The Sydney Opera House's iconic sails were illuminated with images of previous royal visits to welcome the couple, whose six-day trip will be brief by royal standards. Charles, 75, is being treated for cancer, which led to the scaled-down itinerary.

Charles and Camilla were welcomed in light rain at Sydney Airport by Prime Minister Anthony Albanese, New South Wales state Premier Chris Minns and the king's representative in Australia, Governor-General Sam Mostyln.
