It's not the SCG, but ....... (You finish the sentence).
Its not the real SCG but don't tell the locals that. This is Shellharbour Cricket Ground and on any weekend you're likely to see this place as a hive of activity, winter or summer there is always some form of sport happening here.
If sports not your thing then go across the road and you'll find one of the best beaches on the south coast, if not NSW. Its clean clear water, well kept sands and surf patrols make it worth a visit.
When you're at GZ make sure the muggles in the nearby houses aren't watching you. The posted coords will only get you close, I cant make it too easy.
