ACG Parnell College (formerly ACG Junior College) was founded in 1998 and originally provided education for students in Years 7 to 10. In 2007 the college was redeveloped, renamed and expanded to offer places at Years 1 to 13.

In 2019 ACG Parnell College opened its new expansion of the college, named ACG Senior Campus. The campus is located on 9 Davis Crescent, Newmarket. The campus offers Cambridge International Examinations. The new Senior Campus serves Year 11, 12 and 13 only. In July 2020, an Early Learning School was opened.

Mr Larne Edmeades was the school's former Principal, appointed in 2005. Edmeades worked with staff to establish and develop the new ACG campus and left the college at the end of 2016, leaving Mr Ed Coup as the Acting Principal. In early June 2017, Mr Russell Brooke became the Principal and left the school on 1 March 2020, leaving Mr Damian Watson as the current Principal.
