I think someone asked for this info a few days ago. Since 1992, 18 GPS rowers have represented Australia at the Olympics. Some have represented Australia more than once, meaning GPS rowers have filled 33 Olympic spots since 1992. Below is a list of names, their school, their Olympic years, and whether or not they won the AAGPS HOR.
Peter Murphy – Shore – 1992 and 1996 – Won HOR 1985
Richard Wearne – Newington – 1996 – Won HOR 1989
James Stewart – Newington – 1996, 2000, 2004 – Won HOR 1991
Geoff Stewart – Newington – 1996, 2000, 2004 – Won HOR 1991
Steve Stewart – Newington – 2004, 2008 – Won HOR 1994
Matt Long – Newington – 2000 – Won HOR 1991, 1992
James Chapman – Newington – 2004 (reserve), 2008, 2012 – Won HOR 1997
Rob Jahrling – Newington – 1996, 2000, 2004, Won HOR 1992
Al Gordon – Kings – 2000 – Won HOR 1993
Sam Loch – Kings – 2008, 2012, Won HOR 2001
Matt Ryan – Kings – 2008, 2012, Won HOR 2001
Marty Rabjohns (Cox) – Kings – 2008
Toby Lister (cox) – Shore – 2012 – Won HOR 2004
Nicholas Purnell – Shore – 2012 – Won HOR 2008
Dan Noonan – Riverview – 2008, 2012 – Represented Australia at Junior worlds in Year 12.
Dan Burke – St Josephs – 2000 – Won School four at Nationals
Stuart Welch – Grammar – 2004, 2008 – Won Schoolboy Eight at Nationals 1994 and rowed at Junior Worlds.
Francis Hegerty – St Josephs – 2008, 2012
Total of 18 Olympians, for 33 Olympic spots. 13/18 won the GPS HOR. 25/33 Olympic spots won the HOR. Of those that didn't win the HOR, 2 won at the Nationals in Year 12 and 2 went to the Junior Worlds.
Out of the 18 Olympians – Newington 7, Kings 4, Shore 3, Joeys 2, Riverview 1, Grammar 1, Scots 0, High 0. All 7 of the Newington boys were coached by Michael Morgan at school.
Out of the 33 Olympic Spots – Newington 16, Kings 6, Shore 4, Joeys 3, Riverview 2, Grammar 2
So that is 18 Olympians from the NSW GPS spread over a 20 year period. It roughly equates to one Olympian from each year of GPS rowing - out of 8 schools x 9 rowers including cox = 72. (around 1.4%)
What does this mean? Possibly it means that having an Olympic potential rower in your crew increases your chances of winning the HOR. Also, it may mean that winning the HOR increases the likelihood of you continuing on to be an Olympic rower. Alternately, it could just be pure coincidence, or none of the above.
