The school is set in spacious grounds, which include:
- football & cricket oval
- tennis courts
- netball courts
- basketball courts
- a hockey field
- handball courts
- passive recreation areas in garden settings
Oberon is currently implementing the master plan for the grounds to maximise student use. To date a new entrance area has been developed and the decking near the canteen is proving very popular with students. The outdoor performance area is near completion and an extensive series of outdoor exercise equipment has been installed and well used by students.
An outdoor study and recreation space for year 12, a refurbished student shelter area and shade over the decking at the oval will be completed in 2009.
Student involvement in grounds planning through the SRC is actively encouraged.
