When Governor George Arthur, lieutenant-governor of Van Diemen's Land (now Tasmania), was looking for a site to dump his worst convict offenders in 1830, the Tasman Peninsula was a natural choice. Joined to the rest of Tasmania only by the narrow Eaglehawk Neck, the spit was easy to isolate and guard. Between 1830 and 1877, more than 12,000 convicts served sentences at Port Arthur in Britain's equivalent of Devil's Island. Dogs patrolled the narrow causeway, and guards spread rumors that sharks infested the waters. Reminders of those dark days remain in some of the area names—Dauntless Point, Stinking Point, Isle of the Dead.
