In addition to providing support to QES, OSA is also passionate in joining events of QES as to keep a solid relationship with the alma mater. Every year, OSA is invited to join QES sports events to share the spirit of sportsmanship with QES students, staff and parents.

QES Sports Day 2018 Finals were held on 14 November 2018 (Wednesday).

Two alumni joined the 5 km race but were not among the first three finishers.

Two alumni teams competed in the 4 X 100 m Invitation Relay. The mixed team with alumni from 14FA and 18FA as well as an S4 student won the Championship and broke the QES 4 x 100 m record.
