Tennis is played year round by Oakhill students in both the local Hills District competition and the winter ISA tennis competition with all home games played on the College tennis courts.

The Hills tennis competition is a graded competition, played throughout the Hills District on a Saturday morning. Players are put in teams based on their ability rather than their age. Teams comprise of three players. The competition commences in October and concludes with finals in March.

The ISA competition is a school based weekend competition played in terms 2 and 3. As members of the Independent Sporting Association, all students have the opportunity to compete in the ISA competition representing Oakhill. Teams are also graded on their ability. However, it is not unusual for younger boys to make the 1sts - some as young as 12 have played in the Oakhill 1sts in the past - with great success.

The ISA competition involved teams of four players, with each boy playing two sets on a Saturday morning. The competition concludes with finals in the second week of August.

Oakhill wins the 2009 1st V title (for a 4th consecutive year - Undefeated) and the Schools Championship Shield for a second consecutive year. In addition the 1st V were runners up a the Nationals in 2009.

In 2010 Oakhill were once again ISA undefeated premiers for the 5th year in a row.
