Established in 1972, it was named after John Dunmore Lang,[1] the first Presbyterian clergyman in Sydney.

[2] An influential figure in the early history of the college was Dorothy Isabel Knox, Principal of the Presbyterian Ladies' College, Pymble, who guided community appeals for suitable accommodation for ladies.

[citation needed] Dunmore Lang College is governed by a board of directors.

They organise a variety of events throughout the year, including O-week and Dis-o-week activities and the annual pre-Conception Day party.

The college employs fourteen Resident Advisers to provide 24-hour student pastoral care.
