The Law Society of New South Wales conducts an Inter-school Mock Trial Competition. Mock Trials are simulated court cases in which the participating student teams contest a fictional legal matter in a mock Local or District Court sitting. Trials are presided over by a senior member of the legal profession acting as a magistrate.

Year 10 and Year 11 students who have an interest in the Law or who are studying Legal Studies represent the College. Some roles are speaking roles such as the barristers and witnesses while others are crucial 'thinking' and supportive roles such as solicitor.
