From what I understand about 10-15 years ago the school had about 500 boys and now they have 1,200. This has come after a new headmaster arrived. They also have a top class rugby coach in John Papahatzis coaching there. I believe that over 50% of Manly and Warringah junior rep players now enrol at the school in Year 7 and sometimes Year 5. No idea what the fees are, but people tell me they are quite reasonable.
This area has also changed significantly since I went to a CHS school over 30 years ago. Back then there was a strong rugby programme in all the state high schools, Manly Boys' and Balgowlah Boys' in particular featured in Waratah Shield finals and semis and I think Manly may even have won it a couple of times. Manly is now academically selective and co-ed, so little rugby there Balgowlah now has less than half the students that it used to, the North Shore Zone CHS Wednesday competition folded 10-15 years ago, so basically there's not much rugby going on the state system. Now about 60% of students in this area go to private schools, in my day almost all went to their local state school.
So it doesn't surprise me that a private school in the area, which has a good rugby programme is attracting plenty of enrolments. They seem to be doing the right thing in that they are strong all through the age groups, not just opens. That indicates to me that they have talent and a coaching programme in place. I'm told that they draw almost if not all of their students from the northern beaches, so again that tells me that they are taking advantage of being in an area in which rugby is strong.
