Naval Communication Station Harold E. Holt is a joint Australian and United States naval communication station located on the north-west coast of Australia, 6 kilometres (4 mi) north of the town of Exmouth, Western Australia. The station is operated and maintained by the Australian Department of Defence on behalf of Australia and the United States and provides very low frequency (VLF) radio transmission to United States Navy, Royal Australian Navy and allied ships and submarines in the western Pacific Ocean and eastern Indian Ocean.[1] The frequency is 19.8 kHz. With a transmission power of 1 megawatt, it is claimed to be the most powerful transmission station in the Southern Hemisphere.[2]

The town of Exmouth was built at the same time as the communications station to provide support to the base and to house dependent families of US Navy personnel.
