Bossley Park is located 36 kilometres west of the Sydney central business district in the local government area of the City of Fairfield.

After World War II, Bossley Park received many migrants from Italy, who have since played a large role in the local community.

Bossley Park and its surrounding suburbs were rural areas until the 1970s, when they were developed into a residential settlement.

[3][4][5] Bossley Park residents are predominantly Catholic (Latin and Eastern), Assyrian Orthodox and Anglican.

Like most of Sydney, Bossley Park has a humid subtropical climate (Cfa) with warm to hot summers and cool winters.
