sands. Busselton Jetty Busselton is home to the longest wooden jetty (pier) in the Southern Hemisphere, stretching out to sea. Construction of the jetty began in 1864 and it was continually extended until the 1960s, when it reached its current length. It was closed to shipping in 1972, and maintenance was discontinued for a time. Following major damage caused by Cyclone Alby in 1978 and a fire in 1999, it was restored and improved. Since 2003, the jetty has offered visitors a tourist train ride, an underwater observatory, and an interpretive centre. Wonnerup House The current Wonnerup House was built in 1859 by the Layman family (original settlers). The original building built between 1837 and 1841 was destroyed by fire in 1858. The complex also includes the dairy and kitchen, which antedate the main house (and survived the fire of 1858 because they were separate buildings). Over the road are the Teacher's House (1885) and School (1873). Since 1973, the National Trust of Australia has operated the property as a museum open to the public. Old Butter Factory/Busselton Museum The Old Butter Factory was built in 1918 by the government Department of Agriculture to replace a previous privately owned dairy, Western Australia's first butter factory and creamery, that was established in 1898. In 1926 the factory was sold to South-West Dairy Produce Co-operative, which was later renamed "Sunny West" and merged into Wesfarmers. The factory also operated as an ice works for local residents and fishermen before the widespread availability of mechanical refrigeration. It ceased butter-making operations in 1952 and became a cream depot and dried milk plant, then a truck depot. In 1974 it was sold to the Shire of Busselton, which leased most of the building to the Busselton Historical Society; they opened the Busselton Museum there in 1975. It was listed on the state's Register of Heritage Places in 2002. In March 2018, the building was heavily damaged by fire. the outside areas were re-opened in January 2019 and the rest of the building was opened in December 2020. St Mary's (Church of England) St Mary's (Church of England), built in 1844–1845, is allegedly the oldest stone church in Western Australia. John Molloy and John Garrett Bussell were the main forces behind the construction of the church. The church was not consecrated until 1848 and a clergyman was not attracted to the region for another decade. Alongside
