Susan Bruce wrote: “One of the best teachers, loved his science lessons.”

Robert McGregor: “Many fantastic memories of a great teacher and a true gentleman. I remember one afternoon at school a few of us not wanting to go to sport - so he just took us for a bushwalk instead!”

Tracey Hatton: “I remember our laughs and great conversations at school and later on when you taught my children, you were a warm and caring man and you will be sadly missed.”

Monique Anderson: “Rest in peace Mr Holland. You actually made me enjoy science and going to school. I still remember the day my dad got excited cause you were my science teacher just like you were his. You have touched generations of students and will never be forgotten.’’ 

Karen Boden: “Your passion and enthusiasm for teaching and for life was infectious. Your science classes were always filled with fun interactive learning and you always had time for anyone. I will always remember the fun science experiments and bunsen burners and periodic tables.”

Rebecca Keating:  “RIP Mr Holland. Thanks for believing in me.’’

John’s daughter, Melissa Clarke responded to the comments saying: “He still loved seeing ex students. He remembered them all and was glad when they visited. He had difficulty communicating but he sparked up.

“Even in the last couple of weeks that dad spent in hospital, mum said he experienced a real lift in responsiveness when hospital staff he had taught or families of patients who were ex students stopped by.

“Thank you again for this overwhelming flow of beautiful comments.”

Professor Ian Plimer recalled his friend’s life when he delivered the eulogy at Mr Holland’s funeral.
