Western Sydney locals can go for a dip in Lake Parramatta for the first time in more than 70 years.
The swimming hole had its heyday from the 1920s to the 1940s. It closed in 1942 because of water quality concerns, and will reopen to the public this weekend.
"Every Aussie has the right for a cool dip in a beautiful, clean environment without having to drive more than an hour in a hot car to the nearest ocean beach," Parramatta mayor Scott Lloyd said.
The reopening is the first milestone of the district's 10-year plan to revive sections of Parramatta River and the surrounding creeks for public use.
Apart from Lake Parramatta, which is a man-made reservoir, the waters west of Cabarita are unsuitable for swimming.
Lifeguards will be on duty from 9am to 5pm at every weekend until mid-March.
A Family Fun Day on Saturday will kick off launch celebrations with a free sausage sizzle, face painting and entertainers.
