To my Australian friends:
Thanks for contributing the Melbourne Sandbelt topics and comments, they add a lot to this site.
The green complex at 18 on the East course at Royal Melbourne makes it the best I've played in Australia, and I'm not sure what I would put ahead of it in the US, perhaps 18 at Riviera for its natural topography and ampitheatre setting or 18 at Winged Foot West with its wonderful sloping (and historic) green. My perennial favorite, 18 at Pebble Beach, has been significantly compromised by the loss of the Monterey Pines on the right side of the fairway off the tee and to the front right of the green. Even with it a short iron in hand, Royal Melbourne East's 18th is REAL dicey.
As an aside, obviously the RM West course has received attention worldwide (it's my personal #1 in the world), but anyone travelling to Melbourne should really also play and study the East Course. The East course is on flatter land, especially the holes across the road, but there are some great holes, especially 2, 3, 4, 10, 16 (as good as #15 at Kingston Heath), 17, and of course, 18.
I would encourage all those who really love golf architecture, after you make the obligatory Scotland and Ireland trip, to get on a plane and to Australia and see some of the best stuff you've ever seen. Great lovers of golf, too. IMO, 36 holes at Royal Melbourne playing with the members, as opposed to being in a guest group, is as good as it gets anywhere.
