Came to mind after Scott won the Masters
He attended a tiny secondary school called Kooralbyn International School that has only been in existence since 1985.
Alumni include Adam Scott, Jason Day (3rd in Masters), Steven Bowditch (PGA tour member) and Cathy Freeman (Olympic Gold Medallist).
They also have a great academic record
Sports people that attended Matraville High include the Ella Family, Russell Fairfax, Eddie Jones and Willie Tonga
On the downside, Bob Carr also went there as did many (other) criminals
I remember playing rugby against Auckland Grammar, a school that holds the record for producing ABs (they smashed us!)
