Prince Charles and the queen pick up the tab for Will and Kate.
Prince William and Kate's household staff — which includes their tour entourage — is funded completely by the income of Prince Charles through the Duchy of Cornwall, as is Kate's official wardrobe. The Duchy, an estate inherited by the eldest son of the reigning monarch, is worth an estimated $1.2 billion (that's right) and makes a profit of $32 million per year. Will and Kate do not receive money from British taxpayers directly but instead rely on Prince Charles and the queen's grant-in-aid funding to pay for official travel on her behalf.
But it will also cost the New Zealand and Australian taxpayers a pretty penny.
New Zealand media estimates the trip will cost the country's taxpayers almost $1 million. The cost comes in flights provided by the Royal New Zealand Air Force, preparation work, accommodation and meals provided, and media communication costs. In Australia, the trip is estimated to cost about $2 million. Flights alone are meant to cost almost $300,000. Compared to a state visit by a sitting foreign president and his/her entourage, however, the royals are considered inexpensive state visitors.
