Queen Elizabeth II
$668 million AUD
As the head of the family (and of the Commonwealth and the Church of England, casually), Queen Elizabeth is worth the most. Between inheritances from her parents, property investments (she holds the rights to many castles across the British Isles), jewels and—surprisingly—horse winnings, Her Majesty's total comes up to around $668 million AUD.
Charles, Prince of Wales
$556 million AUD
When you're the direct heir to the throne of England, you get more than a fancy title and an appealing promotion. As Prince of Wales, Charles holds the duchies of Cornwall and Rothesay, which have substantial assets. From property, to agriculture, to a hefty investment portfolio, Charles' yearly revenue is lucrative and comes in at around $556 million AUD. (Which makes sense, considering it's Charles that deals out money for clothes and trips to his sons and their wives.)
Prince William, Duke of Cambridge
$56 million AUD
As third in line to the throne, Prince William is in a pretty solid place financially. During his service in the military, then as an ambulance pilot, William earnt a steady paycheck. On top of that, he also received substantial inheritances from both his mother, Diana, Princess of Wales, and his great-grandmother, Elizabeth, the Queen Mother.
Prince Harry, Duke of Sussex
$56 million AUD
Despite us placing him below his brother in this list (older sibling wins out, sorry Harry), the Duke of Sussex is actually neck-and-neck with his brother. The culmination of his military salaries, and his inheritance from his mother and great-grandmother put his net worth at $56 million AUD.
Catherine, Duchess of Cambridge
$14 million AUD
Although you might not have guessed, the former Ms Middleton is actually worth millions. Her parents own a lucrative party supply business called Party Pieces, which Kate briefly worked at—and rumour has it that they have put aside quite a bit of profit for herself and her two siblings, Pippa and James.
Meghan, Duchess of Sussex
$7 million AUD
On top of working steadily as an actress—she reportedly brought in $70,000 AUD per episode of Suits—Meghan Markle also earned money from endorsements, collaborations and her occasional movie appearances.
