Chapman is bordered to the west and south by Cooleman Ridge, part of the Canberra Nature Park.
The suburb is named after Sir Austin Chapman (1864-1926), Member for Eden-Monaro (1901-1926). An enthusiastic advocate for Federation, Chapman was the Member for Braidwood in the NSW Legislative Assembly (1891-1901) and held portfolios in the Deakin and Bruce governments.
Other suburbs in the Weston Creek area include Duffy, Fisher, Holder, Rivett, Stirling, Waramanga and Weston.
Cooleman is an Aboriginal word for ‘shield’ and appears in a lot of Australian place names.
