Mercedes Old Scholars Association (MOSA) A valued part of our community, old collegians play a pivotal role in the continuing development of Mercedes College by generously contributing and supporting volunteer programs, plus participating at special events and functions.

The Mercedes College Old Scholars Association (MOSA) is a glorious network of old collegians who regularly get together, have fun and contribute to the College for the benefit of all students. 

You can follow the Association on Facebook and Instagram where we regularly post updates about our old scholar achievements, coming events, and snippets from the past.

Share your career insights

At Mercedes College we welcome old collegians sharing their insights and providing an inside view of their careers with our Senior School Students - Year 10 to Year 12.

Each year we bring old scholars together with students, so they can gain a firsthand account of tertiary and vocational pathways, career options and the lived experience, and hear how predecessors have achieved their goals and ambitions.

To be involved, simply contact us at or call +61 8  8372 3200 during business hours.
