Margaret Court

Former World #1 Tennis Player, Winner of 64 Grand Slam Titles

"I was fortunate to have Peter travel with me on the professional tennis tour as my coach in 1989, and it remains my most successful year, breaking into the top 50 in the world for the first time. These results were due to Peter’s excellence as a coach, particularly in match strategy, and as a mentor.He instilled confidence in me through his positivity, his passion, his dedication, and most importantly his unwavering belief in me before I knew how to believe in myself. Travelling on the WTA Tour could be arduous, but Peter gave me the mental and emotional skills that enabled me to not only endure, but to maximise my potential. I was lucky to have him in my corner."

Jenny Byrne

Former World Top 50 Ranked Tennis Player‍‍

"Peter coached me when I was a tennis professional. He travelled with me for some time. He was the best coach I ever had and through him I reached a world ranking of 23. He was a true professional and his attention to detail was instrumental in allowing me to reach my potential. He is an exceptional coach, and I was very lucky to have him on my team."

I cannot recommend Peter highly enough.He has guided me through powerful techniques and exercises that helped me gain clarity, escape from self-limiting beliefs, and develop a strong and empowering mindset for any of life’s challenges.

Former World Top 50 Ranked Tennis Player

"Peter Collier has the rare status of being not only a brilliant teacher, but a mentor who has shaped the characters of men. His enthusiasm for his subject is infectious, inspiring his students to extend their knowledge beyond the course, to become informed about the world and to relish learning and academic excellence.I would not be alone in saying that Peter Collier had one of the most fundamental influences on my life. Teachers of the calibre of Peter are rare entities indeed. I count myself enormously lucky to have been taught by such a man."

Professor James McNamara

Former Student, Scotch College

"You tend to find inspiration from the funniest of places. At Scotch, there was always one subject that really interested me and much of that was because of the way it was taught – by Peter Collier. I always enjoyed arguing and being encouraged to argue my opinions in Politics and History. These classes intrigued me and inspired me as I was always keen to give an opinion.Not only did we have to give an opinion but the moment we walked through the door we had to back that opinion up with facts, just like we were adults. I thought that this was great. It was this environment of being treated like an adult if you spoke like one, which really inspired me to become a teacher today. I learnt so much from Peter and I have plenty to thank him for."
