The Mt Druitt Waterworks, was a waterslide fun park, had 6 giant waterslides, pool,spa with beach area, bumper boats, beautiful grounds for bbq and picnics, games room and eventually added other rides, such a shame it closed down, something the area really needed.
The rumors of razor blades were just that rumors, the Park was well maintained and checked thoroughly, I know because I was lucky enough to work there for most of the time it operated, and it was the best job I have ever had.
