AGREED FACTS
10 The facts at [11] - [20] below are agreed.
The radio receiving station and the water tower
11 In about June 1995, a plan was prepared by Godden Mackay Pty Limited entitled "Bringelly Radio Receiving Station complex, Telstra Corporation, Mobile Satellite and Radio Services, Badgery's Creek Road, Bringelly, NSW, Conservation Plan" (the Godden Mackay Conservation Plan) in relation to the buildings on the Land.
12 According to the Godden Mackay Conservation Plan the following events occurred:
(a) in about 1946, the Overseas Telecommunications Commission (OTC) was brought into existence by the Commonwealth of Australia under the (since repealed) Overseas Telecommunications Act 1946 (Cth);
(b) in about 1950-51, the OTC constructed the radio receiving station, a brick utility building, mainly single storey, with a small second storey level and a 3-storey tower adjacent to its entry. This was the only radio receiving facility of its kind built in New South Wales;
(c) in around 1955, other associated infrastructure was also built on the Land, including on-site staff housing comprising 15 staff cottages and one single men's quarters and associated leisure facilities including a pool, cricket ground and tennis court and also including an elevated, bolted cast-iron water tank, which formerly supplied water to the site and OTC staff;
(d) the telecommunications technology originally installed at the radio receiving station in the early 1950's was replaced around 1969 when the facility was converted to an unmanned operation;
(e) by 1995:
(i) one house had been demolished, leaving 15 buildings. Approximately half the houses were leased to Telecom employees and the remainder were empty;
(ii) the second generation technology installed around 1969 had itself been rendered redundant by new satellite technology. The function carried out by the radio receiving station would in future be carried out by a new facility in Brisbane;
(iii) the buildings were recognised as heritage items in the local area. As a result, Council required a conservation plan prior to considering any change of use of the site "to fully consider the heritage significance of the item and the impact of the proposed development on the items".
13 According to the Godden Mackay Conservation Plan:
"(i) back in 1995, discussions with the Liverpool Council Heritage Planner had established that prior to any redevelopment of the site a heritage assessment or conservation plan would be required, and that a conservation plan would be preferred;
(ii) also in 1995, Godden Mackay understood that Telecom had concerns with regard to the structural soundness of many of the buildings and for safety on the site and wanted to demolish the existing complex."
14 The Godden Mackay Conservation Plan included the following recommendations (among others):
"(i) it is desirable but not essential that the Radio Receiving Station is retained, conserved and re-used;
(ii) the water tower should be retained in operating condition subject to structural adequacy and adequate safety provisions."
