Government of Western Australia in the context of "Fremantle Harbour"

Leonard George Casley (28 August 1925 – 13 February 2019), also known as Prince Leonard, was the founder of a self-proclaimed micronation, the Principality of Hutt River, his own farm, within the Australian state of Western Australia. He governed Hutt River from 21 April 1970 until his abdication in February 2017 at a coronation ceremony that placed his son Graeme Casley on the throne.

Having pursued a number of occupations, Casley eventually settled on farming, purchasing a large wheat farm near the towns of Northampton and Geraldton in the 1960s where he came to own 75 square kilometres (29 sq mi). In 1970, he declared independence and founded Hutt River Province in response to a dispute with the Government of Western Australia over what the Casley family considered draconian wheat production quotas. "His Royal Highness Prince Leonard I of Hutt" was the style used by Casley from the creation of the principality until his death.

Western Australia (WA) is divided into regions according to a number of systems.

The most common system is the division of the state by the Government of Western Australia in 1993 into regions for economic development purposes, which comprises nine defined regional regions that exclude the Perth metropolitan region. However, there are a number of other systems, including those made for purposes of land management (such as agriculture and conservation), information gathering (such as statistical and meteorological), and election for political office.
