Danielle Finnimore
Council Chair

As a dedicated parent of two children, now old scholars of Mercedes College, I have been actively involved in our school community for seven years, working alongside fellow parents, staff, and leaders to ensure that every student has the opportunity to reach their highest potential. My commitment to supporting the delivery of the College’s strategic goals remains a key focus of my role as Chair of the School Board.

With a diverse career spanning education, professional services, media, and sport, I bring a wealth of experience in senior Human Resources and Executive Leadership Roles. Currently, I serve as the Executive General Manager, People & Culture at Adelaide Football Club, where I apply my expertise in people management, organisational development, employee engagement, and fostering a strong organisational culture to drive a high-performance environment.

My professional journey, combined with a deep passion for education and creating an exceptional learning environment, allows me to offer a unique perspective on the Mercedes College Council. I am a results-oriented leader, committed to fostering an inclusive and supportive community of learning, where both students and staff can thrive.

I hold a Master’s in Commerce and have recently completed the Foundations of Directorship Course at the Australian Institute of Company Directors (AICD). I pride myself on being a focused, purpose-driven professional with a proven ability to build strong, collaborative relationships. With a strong sense of justice, empathy, and diplomacy, I am dedicated to delivering practical solutions that align with the College’s objectives and enhance the experience of every member of our community.

I look forward to continuing to work alongside my colleagues on the College Council to ensure Mercedes College continues to deliver a world class education for our students.

Jock Duncan

With more than 20 years’ experience in senior HR/executive level roles across a variety of industries, I am currently the Director of Corporate Services at Hood Sweeney, an integrated professional services business in Adelaide.

I have wide-ranging responsibilities, from leading our people and culture strategy, to general management responsibilities, and the delivery of consulting services to our clients. Ultimately, my passions are building a high performance culture capable of achieving our strategic goals and delivering outstanding service to our clients.

A key part of sustaining this culture is connecting back and contributing to the communities we operate within. To this end, I have a key role in leading our focus on helping our chosen charities such as Kickstartforkids, which supports under-priviledged children in primary schools through breakfast and mentoring programs.

This service mindset also led me to become involved with the governance of the College, with a role on the Risk and Audit Committee and now the College Council. Together with Karni, I have two children, Lily and Finn, and a deep commitment to help maintain the school's great legacy, as well as positioning Mercedes College as a leading educator in South Australia.

Troy Trafela

With 15 years of technology experience and 10 years in people management, I've been described as a ‘business enabler’ with a niche for connecting the dots and enhancing businesses through operational reviews, technology implementations, and creating a culture of ‘the art of possible’.

Within my career, I have managed teams of up to 100 and had ownership of portfolios of 15M across multiple businesses. I continue to drive my results through my skills in people, problem-solving, operational and business strategy, process improvements, digital innovation, customer experience, finance and sustainability.

Supporting the community and institutions that develop, nurture, and guide the next generation is something extraordinary that not many have the privilege of being involved with. I am a proud Mercedes College parent, with my eldest son Marco enrolled since 2021 and Keanu since 2024.

Michael Callisto

As a Mercedes College student from 1986 to 1998, and now as a parent, I would like to give back to the community that has been a big part of my life.

I joined the Committee at an exciting period in its history, with the opening of the Yitpi Centre and Gleeson Theatre and the 70 year anniversary in 2024, and I believe my background in Business Management and Finance and ownership of our own family business gives me the necessary skills to contribute to the College Council in a meaningful way.

Toby Hughes

My wife and I have been fortunate to have five children attend Mercedes; each has had a different journey.  They have benefitted from the overall leadership and governance provided by School Council, and I’d like to repay this support.

I have a significant track record in tertiary education and research leadership, which would be valuable additions to the skillset of the Council. I have a professional interest in educational and pastoral transition from secondary to tertiary education, and I look forward to providing valuable input into processes and systems designed to help senior students make good choices to support their career aspirations.
