Khaberni - The District of Columbia, which includes the US capital Washington, mistakenly placed several Australian flags instead of British ones near the White House, just before King Charles' visit to the United States, but this error was quickly rectified.
King Charles is also the ruler of Australia, but this role is largely ceremonial.
An official in the Department of Transportation said that for a short time, 15 Australian flags were raised among more than 230 flags to welcome the King of Britain upon his arrival in Washington on Monday, but they were later replaced with British flags.
Charles' official visit, which commemorates the 250th anniversary of the United States' declaration of independence from British rule, is widely regarded as the most significant visit since his ascension to the throne.
The visit aims to strengthen the "special relationship" between the allies, which has reached its lowest point in 70 years amid tensions surrounding the war with Iran.
The British government hopes that King Charles III's visit to the United States will mend the deep rift between the allies caused by the Iran war.
The King and his wife, Queen Camilla, will travel to Washington on April 27, in what appears to be a four-day trip to celebrate the 250th anniversary of the United States' independence from Britain, but it now carries much greater significance amidst growing disputes between Trump and British Prime Minister Keir Starmer.
A Buckingham Palace spokesperson said on Tuesday: "This visit... acknowledges the challenges faced by Britain and the United States and our allies around the world. It also represents an opportunity to reaffirm the importance of our bilateral relationships and strengthen them as we collaborate to address these challenges, serving Britain's national interest."
The spokesperson revealed details of the trip, saying that US President Donald Trump and First Lady Melania Trump will welcome the King and Queen in Washington at a special tea party, followed by an official reception at the White House, a formal dinner, and a meeting between the King and the President.
