Martin,
I am disappointed to be missing the telecast, but I cannot recommend Lake Karrinyup enough. There are really only 5-6 courses in Australia that are better. It has that fantastic ability to be challenging whist still being enjoyable. It is a beautifully balanced course.
The course probably lacks a "great" hole but at the same time there isn't a weak hole out there.
Even though it is in Perth, the course design borrows significantly from the sandbelt. A lot of courses have copied the bunker style from the sandbelt but nothing else, which misses the point of what makes the sandbelt courses so good. The redesign at Lake Karrinyup does not have sandbelt style bunkers but it coppies many other principles that make sandbelt golf great - space to play, strategic greens with open fronts, elegant contouring, and well managed vegetation.
A lot of sandbelt courses could learn a lot from a visit to Lake Karrinyup, if they visited with open eyes and minds.
