MBC Leos has been running in the College since 2007. It provides an opprtunity for boys to give service to the College and the wider community. There are also opportunities for boys to develop their organisational and leadership skills.
Boys take part in a number of fundraising activities during the year. Past activities have included leaflet drops, raffles, and a sausage sizzle at the Mistletoe Market. The money raised is donated to different causes. The Leos have donated to the College Library, to Leos members representing the College and to the Famine team. In 2008 the Leos presented two cups to the College to be presented to a Year 12 and to a Year 13 student for gaining Excellence credits in the previous year.
Leos have provided service to the community by planting trees, cleaning up river banks and putting on a dinner at John's Kitchen.
There are also social occasions such as the Ramfurly Shield competition which pits members against other Leos and Lions clubs. Paintball is a popular activity.
