Chullora is located 15 kilometres west of the CBD. The suburb was originally part of the area known as Liberty Plains. In the 1950s, many immigrants from Europe were housed in the area and only once they were established, they moved to other parts of Sydney. Chullora was the name of one of the estates in this area which eventually got adopted as the name for the suburb.
During World War II, Chullora was the site for a big war time manufacturing plant. This site occupied several hundred acres of land. The site is described as the largest secret manufacturing plant in Australia. Over two-thousand men and women worked at the factory.
