Executive Team


Mark Gillett

I have had extensive experience, both as a teacher and school leader, in seven senior high schools and colleges in both metropolitan and regional locations, mostly in low SEI contexts. I maintain a current interest in Science and Mathematics teaching and learning and have a Master’s Degree in Educational Management as well as being a member of ACEL.


I strongly believe that regional schools have a unique set of factors that need to be addressed to make sure students and communities are not disadvantaged.


I believe that our state system has a responsibility to provide all students from all backgrounds with the education they deserve, free from privilege. And that the public school system “should be one that is proud to provide the keys to unlock a million futures”.


A place where students feel safe and can achieve to their own potential.

Associate Principals

Associate Principals coordinate, manage and monitor the educational program and pastoral care needs of students across all year levels. They have a shared responsibility to ensure all students are able to fulfil their learning potential in a safe, inclusive, supportive and culturally responsive environment. They work closely with Year Coordinators, Heads of Learning Area and teaching staff to support all students in their respective year groups. The Associate Principals oversee all significant educational programs, personalised pastoral care approaches and individualised teaching and learning adjustments as well as understanding the specific needs of the whole cohort.

Associate Principal (Year 7 & 8)

Tenielle Billing

I grew up in Bunbury and my first teaching position was back at the high school I had attended only 5 years earlier, Bunbury Senior High School. I moved back down south after teaching at Perth Modern School and Ballajura Community College. I have been at CNC for 12 years and in this time have undertaken a number of roles. I am committed to maximising the academic, creative, social and personal potential of every student. I feel fortunate to be a part of the Cape Naturaliste College Community and look forward to taking on the role of Associate Principal.

Associate Principal (Year 9 & 10)

Jacqueline Bovell

I am a Busselton girl born and bred. I grew up here and went to West Busselton Primary and graduated from Busselton Senior High School.

After 18 months at John Forrest SHS and a 12 year stint at Kent Street SHS as a Year Coordinator, Beacon Foundation Coordinator, Health Education Specialist, HOLA of Health and Physical Education and Senior School Coordinator, my husband and I decided it was time to return to our roots and head home.

After watching the College grow and succeed so quickly from afar, it was an absolute pleasure to have the opportunity to join the team at Cape Naturaliste College as the substantive HOLA of Health and Physical Education. Throughout my career I have have adopted many Leadership opportunities and have settled into my role as Associate Principal with pride and compassion.


It has been a pleasure to join the leadership team at Cape Nat as we as a whole school strive to support our students and staff to achieve their potential.

Busselton has most definitely changed over the years and the opportunities are plentiful. That’s why it is so important that we as a community work together to develop our young people, help them to dream big and aspire to be the best they can be.

This place is my home. I am committed and passionate about our community and look forward to supporting our students to develop into successful and inspirational young adults.

Melanie Ryan

I started my journey as a high school educator in 1994 with my first teaching position in the Wheatbelt. Since then, I have taught at District, Middle and Senior High Schools in the areas of English, Society and Environment and Physical and Health Education. In 2008 I joined Cape Naturaliste College and had the privilege of helping to establish the college and work with such an energetic, dynamic and enthusiastic team of teachers and administrators.


Working at Cape Naturaliste College has been an exciting and rewarding experience and in recent years, I have also had the opportunity to work closely with our local primary schools in supporting the transition of students to the college. I look forward to watching these students play an integral role in the development of the local community and shaping the identity that is Cape Naturaliste College.
