Colin Russell, the Greenpeace activist detained in Russia since September, has arrived home in Hobart.
Russell was one of the Arctic 30 who were arrested during a protest against oil drilling by the Russian energy company Gazprom.
The protesters were charged with hooliganism and faced lengthy jail terms but the Russian parliament passed an amnesty law in December which led to their release.
Russell, 59, spoke to the media in Hobart.
