Mr Halliday joined Mentone Girls’ Grammar as the Head of Junior School at the beginning of 2023.

He was appointed to this role after concluding his tenure as a Primary School Principal at an International Baccalaureate (IB) World School in Ho Chi Minh City, Vietnam, where he gained invaluable experience in IB programmes.

Prior to this, Mr Halliday was the Head and Deputy Head of the Junior School at Caulfield Grammar School (Wheelers Hill Campus), and brought to the role more than a decade of experience teaching at various year levels (PK-12).

Mr Halliday believes that magical moments happen between the teachers and students each day and it's ultimately these moments that have the greatest impact on student learning.
