I have never been to the USA but I have played nearly all of the Australian courses listed on golf Digest's 100 best courses outside of the USA.
2. Royal Melbourne G.C. (Composite) Black Rock, Australia
(never played the composite course but have played the East & West courses that make up the composite course plenty of times.
8. New South Wales G.C. Sydney, Australia
(have played here more than 50 times, it's probably my favourite course)
13. Kingston Heath G.C. Melbourne, Australia
32. Royal Adelaide G.C. Adelaide, Australia
35. The National G.C. (Moonah) Cape Schanck, Australia
(anyone complaining about Augusta being long this year should play Moonah and find out just what long is!)
66. Metropolitan G.C. Melbourne, Australia
68. The Lakes G.C. Sydney, Australia
(I play here a few times a year)
49. Barnbougle Dunes G. Links Bridport, Tasmania, Australia
(I haven't played here yet but I am booked in for a week in October)
