Douglas Park is a town of the Macarthur Region in New South Wales, Australia in Wollondilly Shire.

[2][3] The two largest land grants in the district were those of Dr Henry Grattan Douglass[4] and Jean Baptiste de Arrietta.

[6] Douglass had numbers of convicts working on his farm, as muster rolls in the State Records of NSW show.

[4] The railway reached Douglas Park in 1863 as a station on the extension of the Main South Line from Campbelltown to Picton.

We left Annie, then Lil and I hurried off and caught the 5 o'clock train to Picton to stay with the Daintreys.

The community includes an historic sandstone house that was once the home of famous New South Wales surveyor Sir Thomas Mitchell.

The Saint Mary's Towers Retreat Centre is also located here, utilising the historic novitiate and junior seminary buildings, and the local Catholic community of Douglas Park and Wilton is based here and uses the historic, timber Sacred Heart Church for their liturgical celebrations.

[11] Buses and trains now carry the town's secondary students to high schools in the Wollondilly Shire and beyond.

The causeway crossing the river on Douglas Park Drive is a popular swimming and canoeing site for residents, and others from surrounding districts.

[14] A vertical slot fishway was installed as part of Sydney Catchment Authority's Weirs Project.

[17] At this location also are the Douglas Park twin bridges, carrying northbound and southbound lanes of the F5 Freeway over the Nepean River.

[18] In 2007, Douglas Park residents expressed concern that coal-mining in the area would cause the collapse of either or both of these bridges, possibly resulting in many deaths.
