Physical Education at Mill Park is a co-curricular activity.  It is offered to all students in Years 7-12 and includes major carnivals, team sports and individual sports.  Competition is structured into House and inter-school activities.

Major intra-school carnivals in the form of House competitions are held during Terms 1 and 2.  Athletics and Swimming are held during Term 1, and the cross country which is run as a fun run is held in Term 2.
