SF (formerly Sci Fi Channel) was an Australian subscription channel that aired science fiction, fantasy and related programs. It was available on Foxtel, Austar and Optus Television subscription platforms. In 2012 the channel rebranded from Sci Fi to SF. The channel used a world-exclusive version of the "Syfy" branding, SF being a joint venture between NBCUniversal (the owners of the Syfy brand), Sony Pictures Television and CBS Studios International. On 31 December 2013, SF ceased broadcasting and closed, being replaced by an Australian version of Syfy in 2014.
