“Having close connections with our parents, staff and community, is integral to a rich learning environment. When we work together, we can achieve amazing things”
Karen Yager,
Hills Grammar
“I believe that students learn in a supportive environment with passionate and inspiring teachers and staff. We surround our students with positive creative and inspiring people, enthusiastic about their own learning and keen to immerse students in the spirit of life-long learning across the whole community”
Karen Yager,
Hills Grammar
St Aidan’s Anglican Girls’ School consistently delivers outstanding academic outcomes shown by a median ATAR of 94.95 in 2025 and strong NAPLAN results across year levels. Behind these achievements is a school that understands sustained excellence begins with how it treats the people responsible for delivering it. The school’s commitment to people is not just a policy position. It is woven into the fabric of daily life at the Corinda campus, from how staff are onboarded and developed to how they are recognised, heard and supported throughout their career.
Investing in people
One of the most distinctive expressions of St Aidan’s commitment to its staff is the Karen Spiller Fellowship. Named after the school’s long-serving former principal, the Fellowship provides staff with bursaries and dedicated time to pursue research and professional inquiry aligned with the school’s strategic priorities and ethos. This initiative signals that professional curiosity is not just tolerated at St Aidan’s – it is actively funded and celebrated.
Beyond the Fellowship, the school also supports staff through a broad range of professional development opportunities, including further study, mentoring and coaching, peer collaboration, and access to local, national and international conferences and professional networks. Development is personalised rather than prescribed, recognising that great educators have varying ambitions and needs at different stages of their careers.
Wellbeing by design
St Aidan’s commitment to staff wellbeing is reflected in both its policies and its physical environment. The school’s campus offers a fully equipped gymnasium, cafeteria and convenient access to public transport, creating a working environment that supports health and convenience every day.
Smaller class sizes reduce workload pressure and allow teachers to build meaningful relationships with students, contributing to both professional fulfilment and student outcomes.
A well-supported Employee Assistance Program complements a broader commitment to recognising staff as whole individuals, while the school’s annual Staff Awards celebrate educators whose work demonstrates dedication, leadership and care.
Leadership with direction and trust
The school’s leadership structure is built on clarity, collaboration and trust. Principal Toni Riordan, Deputy Principal Geraldine Ebbrell, and Director of Business and Operations Toni Williams provide strategic direction while placing genuine trust in educational and senior leaders to lead confidently within their own portfolios. The staff are also active contributors to that direction, participating in committees and long-lead initiatives that shape the school’s most significant decisions.
This spirit of inclusion extends to the school’s Partners in Learning framework, which brings staff, parents and students into open, reciprocal conversation on diversity, equity and inclusion.
For educators seeking a school where their contribution genuinely matters, where professional growth is actively supported and where a values-based community provides the foundation for outstanding work, St Aidan’s Anglican Girls’ School represents a compelling opportunity.
Learning designed for educators
The centrepiece of Hills Grammar’s approach to staff development is its Professional Learning Model, led by director of professional learning Dr. Chris Furner. Grounded in adult learning pedagogies, aligned with the school’s strategic intent and staff profile and standards, the model deliberately moves away from compliance-driven professional development towards something more meaningful. This is delivered as learning that is authentic, research-based and tailored to where each educator is in their career journey.
Supporting this is the Learning Centre Staff Program, which creates structured opportunities for staff to share practice, reflect on their work and learn from one another. Mentoring, leadership development and action research opportunities are embedded throughout, making professional growth a continuous and collegial practice rather than a periodic obligation. It is a model that reflects Hills Grammar’s commitment to investing in the people responsible for delivering its educational vision.
Future-forward leadership
The school’s commitment to its team extends to how Hills Grammar approaches leadership. Working in partnership with the governing council, school leaders maintain a shared focus on developing what the school describes as a ‘future fit’ graduate and the workforce equipped to teach them. Innovation is encouraged, and the culture is one where academic ambition and professional development are seen as inseparable.
Wellbeing in a remarkable setting
Staff also benefit from complimentary wellbeing programs, a genuine commitment to work-life balance and access to an Employee Assistance Program. Additionally, for educators who value a workplace where the physical environment itself is part of the daily experience, Hills Grammar’s picturesque campus offers a setting that is as restorative as it is inspiring.
There is also a proactive approach to diversity, equity, and inclusion (DEI), such that employees are informed and educated through integrated professional learning frameworks. Hills Grammar is proud to be actively shaping bold thinkers, and in turn empowering the people who teach them.
