Mercedes Old Scholars Association (MOSA) A valued part of our Mercedes College Community, our old scholars play a pivotal role in the continuing development of Mercedes College by generously contributing and supporting volunteer programmes, as well as participating at special events and functions.

MOSA plays a pivotal role in the continuing development of Mercedes College by supporting volunteer programmes, participating at special events and functions and generously contributing to college life for our students.

While continuing to expand their services, our old scholars engage current members and encourage new ones to join the fun.

Youi can follow MOSA on Facebook, where we regularly post updates about our old scholars, coming events, fun college history snippets plus each week we post our popular 'Flashback Friday'.

MOSA Career Mentoring

Each year Mercedes old scholars provide career advice to our Year 11 and 12 students as part of the MOSA Career Mentoring Programme. A wide variety of careers are offered and students have the opportunity to hear from old scholars currently undertaking  tertiary study as well as those people now working in their chosen field.
