Thankyou Ran, Tim, Andy, and Jeff for your comments.
Jeff:
Your impression that many of the Sandbelt clubs have changed from their origianal layouts is accurate. Even RMGC is not immune, having relocated from East Malvern to Sandringham, then to Black Rock. However, once the club was finally settled at Black Rock (1931), they have had little cause to change/tamper with the layouts. Naturally, minor changes have taken place, almost imperceptively.
By comparision, Kingston Heath has undertaken more structural change: significant mounding on the 2nd, 6th green reconstruction, new dip in front of 7th green, 11th hole - huge controversy over installation of bunker in middle of fairway/tea-trea removal/tee location, 12th hole new back tee and clearance of left-hand tea-tree, which ultimately led to the discovery of some original bunkers (buried over time) and now reinstituted, 13th hole bunkering and green work, 14th green, plus 18th hole fortification. In my opinion, the KH changes have been excellent and usually forward thinking, without sacrificing the character of the course.
In 1925 KH was a bogey 82, then 80, then 78, then 76, 75 ... and so on. It explains why some people are mystified about KH's uphill 17th hole - "what an odd par 4" ... some say. Well, it was a par 5 for most of its life! With the passage of time, ten par 5s have been reduced to par 4s.
The incidence of design and history buffs within the Sandbelt clubs has risen slightly over the past ten years, but only just! Like most golfers around the globe, Melburnians generally tap into golf for aesthetics, a bit of exercise, and to give the ball a jolly good belting.
However, at committees and board level, there is a strong movement to form foundations, history committes and so on. Nevertheless, this doesn't seem to be rubbing off on the general club membership.
