The George Hunter High playing fields are made up of a standard high school sized football field with a track around the outside, and a smaller baseball field. There are two sets of three bleachers along either side of the football field with the middle bleacher being much larger than the two on either side. This gives the stadium a rough capacity of around 2,500 when it is fully set up for a game. Students are freely allowed to go on the bleachers before, during breaks, and after school.

Inside the athletics building and down the main corridor past the gym are the indoor courts which consist of a basketball court and two badminton courts. There is a divider that can be pulled across the badminton courts when both are in use. The basketball court has two sets of bleachers that make it able to seat roughly 500 people for a game.

The gym, despite its name, is actually two halls of differing size, divided by a wall with a window. One half is a flat matted area, set aside to give the school's wrestling, cheerleading, and gymnastics teams a practice space of their own, while the other half is a more traditional gym featuring exercise machines such as treadmills, rowing machines, exercise bikes, and other equipment. The students are allowed to use the gym's exercise facilities outside of school hours, but they are required to sign in and out. Anyone found to be misusing the equipment provided will be banned for a two-week period, although these bans can escalate to semester length or become indefinite should the behavior continue.

George Hunter High's Olympic sized swimming pool is one of its unique selling points and as such features heavily in the brochures for their athletics program. Unlike the rest of the athletics facilities students are not allowed access to the pool area unless they are accompanied by a member of staff, and as such the door leading to it and the changing rooms are beyond an electronic lock, so as to prevent any students getting in when they shouldn't. This hasn't stopped some of the braver or more enterprising students wedging the first escape door open to get inside, however.
