The opening ceremony included student performances and speeches. After the event, the time capsule was unearthed after 50 years and pictures of its contents can be found below. The original documents are in the safe hands of the Ipswich Historical Society. After unearthing the time capsule, attendees enjoyed food and market stalls, as well as entertainment rides, located on the senior oval.
On December 2, 2024 the school closed the time capsule for 25 years. On this day, approximately 700 students touched the time capsule cylinder in the hope they will remember this in 2049.
