Hi Andrew,
I’m a Sydneysider who is a member at Newcastle GC. I’m happy to drive the 2 hours on a regular basis because, at a GCA level, it is so much better than anything in Sydney, apart from NSW, which has a 10+ year waiting list for membership.
The north side courses are overrated & similar in overall style. Avondale, for the reasons you stated, is probably the best these days, but they are all much of a muchness.
The new work at Royal Sydney is quite reasonable & causes me to place it higher than The Lakes & The Australian. Ross Watson, who did the recent work at Royal Sydney, is also in the process of working at Bonnie Doon. The new stuff so far, looks good & when completed, will probably see Bonnie Doon given greater consideration by the various ranking panels.
Twin Creeks is a new course open about a years ago, designed by Greame Marsh. It’s a housing estate course with some single fairway corridors & is frightfully over bunkered. It’s worth a hit for Sydneysiders, but not really a tourist destination.
Macquarie Links is about 3-4 years old & is a housing estate as well. Again, worth a game for those who live close by.
Camden Lakeside must be about 10 years old now. It’s a Peter Thomson design with pot bunkers & links style greens, all 45 mins drive from the ocean in heavy, hard packed clay soil amongst gum trees. At least it doesn’t have any dry stone walls.
Sydney suffers through not having a large enough area of sandy soil like Melbourne’s ‘Sandbelt’. There is a strip from NSW GC, through Bonnie Doon & up to Royal Sydney, but that is about it. Everything west, south & north of that is clay.
Sydney is also infested with Kikuyu, with all but 5 or 6 courses where it is the dominant grass. Most of these courses don’t manage the Kikuyu very well & probably 75% of Sydney courses are over treed.
