Port Arthur tour is also worth considering while visiting Australia
. Formerly a timber station, Port Arthur has become one of the most notorious penal colonies of Australia. It is famous for prison which housed inmates as young as nine and is regarded as Hell on Earth'. The prison was in operation from 1833 to 1877 and later it was renamed as Carnarvon in an attempt to shake off its murky history. However, later in 1927, the title Port Arthur was regained. Now days, the prison doors are passable in both directions with harbor cruises and guided tours.
