The PMG / Telecom / Telstra tower was built in 1961-1963 as a relay station to support television and radio links between city and regional broadcasting stations. The tower itself was 45 m in height with a 2 storey building for equipment and staff surrounded by garden. From the beginning it was opposed by local residents. The location is said to be the second highest site in Melbourne, sometimes described as Delaney's Hill.Two A3 photocopied sheets of a map showing part of Surrey Hills, roughly between Windsor Crescent and Belmont Street (north / south) and Standard Avenue and Balmoral Crescent (east / west).
