Australian activist Colin Russell could be home in time for New Year if Russian authorities grant the Greenpeace campaigner an exit visa on Friday.

Mr Russell, 59, is one of 30 activists arrested and detained in September for protesting against a Russian oil rig operated by Moscow-based energy company Gazprom in the Pechora Sea.

Known as the Arctic 30, the group, made up of 28 Greenpeace activists and two freelance journalists, was initially charged with piracy, which was downgraded to hooliganism.

However, the charges were dropped last week after the Russian parliament passed an amnesty law and freed the defendants.

Mr Russell, from Woodbridge in Tasmania, will visit the Russian immigration service on Friday with his wife, Christine, and daughter, Madeleine, and hopes to get his passport stamped so that he can leave.

If all goes well, he could be flying out at the weekend and be in Hobart before New Year's Eve.

''It's wonderful news that Colin will most likely see in the new year at his house in Woodbridge,'' Greenpeace communications manager James Lorenz said.

''He has been incredibly strong throughout, never losing his sense of humour, but this final step is undoubtedly a huge relief.''

Mr Lorenz said Mr Russell was ''desperate'' to get home since his arrest three months ago.

Meanwhile, two other Australian residents, Alex Harris from Sydney and Jon Beauchamp from Adelaide, are also waiting for their exist visas and could be back in Australia by the middle of next month.

Mr Lorenz said Ms Harris was expected to travel first to Britain to see her family in Devon, while Mr Beauchamp would go to New Zealand before returning to Australia.

The first Arctic 30 Greenpeace activist, Dima Litvinov, left Russia by train on Boxing Day.

During the protest, the Greenpeace ship Arctic Sunrise was boarded by soldiers on September 19 after campaigners tried to attached a banner to the Gazprom platform.

Mr Russell had received Australian consular assistance.

Officials from the Australian embassy in Moscow visited him at the St Petersburg detention facility on November 21.
