This was my old list from nearly two years ago. Time for an updated list after seeing New Zealand.
1: National Old - Absolutely the craziest greens I've ever seen. Could never tire of playing here.
2: Kingston Heath - Very solid course with a great finish. Awesome bunkering.
3: New South Wales - Some amazing holes mixed in with some poor ones.
4: Royal Queensland - Options, fun, variety, elegance. Just a wonderful, wonderful course.
5: Royal Melbourne West - Love the green complexes and especially the 6th hole. One of my favorites anywhere.
6: Royal Sydney - Good solid course. Nothing special.
7: Elanora CC - I have a soft spot for the place. Love some holes and the condition is impeccable.
8: Magenta Shores - Just a nice place to play golf. It's one of the toughest courses I've played.
9: Royal Canberra - Like number 7. Not a 'great' course but a very enjoyable place to play nevertheless.
10: The Lakes - Unusual start with 6 par 4's in a row. I love some holes here but like NSW, I believe it has too many poor ones/over the top.
11: Alice Springs GC - Desert course in the center of Australia. Absolutely loved it.
12: Newcastle GC - Nice Apperly course with a very solid F9.
13: Pennant Hills GC - Nice members course.
14: Avondale GC - 10th hole is one of my favorites anywhere. However it must be the most humid place in Sydney.
15: Monash GC - Good finish but would just be an average course if it weren't for the greens.
