 The Longneck Lagoon area is located in the north west corner of the park and surrounds Long Neck Lagoon.Aside from its important natural values as a wetlands and vegetation reserve containing endangered and vulnerable species, the area contains earliest evidence of one colonial use associated with the park when it was still the Pitt Town Common.The large sandstone quarry located between the end of Phipps Road, Cattai Road and the Longneck Lagoon Field Studies Centre commenced operation in the mid 19th Century and continued well into the 20th Century after the Common was decommissioned.
