From the resort website:
Rich River offers two distinct Championship golf courses on the Murray River, immaculately groomed and playable all year round.
The West Course stretches to 6,227 metres off the men’s tees, playing to a par of 72. Ladies benefit from an extra shot on the 5th, playing this tough par-4 for the men as a par-5. Opened in 1979, the West Course has been host to many professional events. It has a tight layout with tree-lined fairways and elevated greens making scoring perhaps tougher than on the East Course.
The East Course, though, is no pushover. Measuring 6,247 metres off the men’s tees, it plays to a par of 72. Redesigned by Peter Thomson in 1998, the East Course links style with water coming into play on several holes.
