At the front of the main side of its two-part campus the Old School House building, now a museum, is situated and contains photos and items pertaining to education in Australia's early colonial era and beyond.

The main part of the school is on the north side of Macquarie Street, and hosts the 65 m tall tower building,[2] where the classrooms, gym, and offices are located.

Before the tower was finished, the architectural front and main entrance of the school faced Smith Street, however it was rarely used and was an artefact of a different structure which was changed due to the building's numerous appendages.

[6] On 23 November 2020, the school went to lockdown after a stabbing attack on a 14 year old male student, NSW Police was alerted at 8:30 am and searched around the area.

The boy suffered serious injuries after multiple stab wounds on his body and was taken to hospital soon after, however, classes were resumed after the incident unfolded.
