Interesting points here. Thanks Philip for a great thread.
Andrew T and Chris are correct in that St. Andrews Beach should be in the Oz Top 10 for some time to come, and will almost certainly climb higher as more people see it.
Mark, I wish you'd leave the personal stuff out of it.
Barnbougle possesses all the subtlety of St. AB, and it's also laid over a dramatic and beautiful site. That's a primary reason why many view it as better than St. Andrews Beach.
Mind you, St. Andrews Beach is much of what future courses should aspire to be like. Very high playability, and very enjoyable. Wide, imaginative and different green complexes. Holes on the edge of par. It really is a course one could play daily for many years - and you'd never feel tired of it.
