Until recent development of the site, a deep pit covered approximately 50 - 60% of the total brick pit site and measured about 230 metres long by about 80 metres wide and was about 16 metres deep. The entire site was enclosed by a cyclone fence, preventing public access. Over many years, the pit had become half-filled with water, making a natural lagoon. The remainder of the site was covered with overgrown trees and plants and had become home to many diverse species of animals most notably bird life, which could be seen nesting and swimming on and around the water. The threatened Grey-headed Flying Fox has been observed drinking from the lake.
