Jannali is a suburb in Sydney, located 28 kilometers south of the Sydney CBD. Jannali is an Aboriginal word, meaning the Place of the Moon, originating from the people of the Northern Territory. The area began to develop with the arrival of the railway line in 1884. However, the railway station at Jannali was not built until 1931. This attracted residents to the suburb and many more homes were built after World War II when blocks of land were offered to returned servicemen.
Jannali is a mainly residential area with a shopping centre beside Jannali railway station. The residential streets feature many houses, units and local reserves which contain a diversity of flora and fauna. Jannali Reserve is a large recreational area on the western border.
Jannali boasted a 10-court Squash Centre between 1978 and 2001. During the existence of the Squash Centre, Jannali Squash Club, who leased courts at the centre, produced many players of first grade standard and in the mid-1980s was considered Sydney’s leading Squash Club and one of the strongest in Australia. According to the 2006 Australian Bureau of Statistics Census of Population, there were 5,495 people usually resident in Jannali.
