The Convict Lumberyard provides a unique openspace setting for important historic buildings and is an especially important part of Newcastle’s convict past. It is of National significance and was Gazetted as 7(d) Environmental Protection Heritage Site Zone by the Minister for Planning in 1992. Under the modern planning scheme the Convict Lumberyard and Enterprise Park should be zoned 6(a)Openspace the same as Fort Scratchley.
Enterprise Park was the first part of the Newcastle Harbour Foreshore Park completed in 1986 to mark the Centenary of service to the Newcastle Region by the Chamber of Commerce and Industry 1886 - 1986. It was zoned for open space in 1960 and the Open Space 6 (a) Zone should be restored as the appropriate zone for the Park.
