[2] It also contains several preserved historic sites from the early Swan River Colony era of Western Australia, including the homestead of pioneer settler Henry Bull and the final resting place of Noongar warrior Yagan.[6][7] As a result of the French reports of Western Australia, British naval officer Captain James Stirling led a party from the HMS Success on an expedition up the Swan River, to survey the area for colonisation potential.As Leake elected to reside in Fremantle, he hired Henry Bull to live on the property, establish pastoral agriculture and work the lands into a profitable state.[15] Their bodies were buried on the north shore of the Swan River nearby, but Yagan's head was cut off and taken away from the area in order to claim a bounty that had been placed on him.Leake gifted the northern half of Swan Location 1 to Bull for his efforts,[10] then surrendered the unprofitable western two-thirds (the site of modern-day Ellenbrook) back to the Crown.After Bull left the area, Leake leased the Ellen's Brook Estate to Cruse and farmers Saul Spice and John Connolly,[10][17] who all continued to work the lands while raising their families there.Unlike past colonial land uses, Barrett-Lennard aggressively pursued viticulture across the estate, initially using Cruse's mill for irrigation[20] until replacing it with a new dam and earthworks.[24] Subsequent generations of the Barrett-Lennard family carried the Belhus viticulture business into the 20th century, expanding into grape exports to Europe[25] and South East Asia.[29] The remaining eastern half of Belhus was subdivided into 36 residential lots by the Barrett-Lennards the following year, necessitating the construction of Millhouse Road and its accompanying bridge across the Ellen Brook.[32][16] In 2014, an extensive wetland monitoring station was constructed near the millhouse by the state government's Department of Biodiversity, Conservation and Attractions, to manage nutrient levels within the Ellen Brook catchment.
