Etherline was an Australian science fiction newsletter published in two series, the first covering issues 1-100 was released between 1953 and 1958; the second, Etherline II, began in 1968.
Most issues of the first series of Etherline were edited by Ian J. Crozier, and published by Mervyn Binns. Leo J. Harding, later known as Lee Harding, was also an editor.
Contributing artists included Mervyn Binns (Australian Science Fiction Newsletter), Ditmar "Dick" Jenssen, Margaret Duce (Helena Roberts Binns), Don Latimer, and Keith McLelland. Contributing writers included Nigel Jackson, Bob McCubbin, and Marshall McLennan.
Race Mathews writes, "Etherline - a newszine produced largely on a collective basis - established what may well have been a record for the fan publishing circles of the day, by appearing regularly at fortnightly intervals for 100 issues, from 1953 until 1958."
Lee Harding, Dick Jenssen, and Race Mathews were all founding members of the Melbourne Science Fiction Group, and Etherline was one of at least five publications the members created, others being Bacchanalia, Perhaps, Question Mark and Antipodes, all made possible by Amateur Fantasy Publications of Australia.
