The principality was a regional tourist attraction until it announced it was closed to tourists after 31 January 2020. It issued its own currency, stamps and passports (which are not recognised by the Australian government or any other government). The micronation was founded on 21 April 1970 when Leonard Casley declared his farm to be an independent country, the Hutt River Province. He attempted to secede from Australia over a dispute concerning wheat production quotas. A few years later, Casley began styling himself as "Prince Leonard" and granting family members royal titles, although he did not include the word "principality" in the official name until 2006.
