The Penitentiary at Port Arthur in Tasmania is but one of many historic buildings at this very popular tourist destination, but don't let that put you off as the site is quite large and you won't have to elbow your way through crowds to "see the sights." It's an easy stroll to take your own tour or you can join a guided tour. There is also the Ghost Tour which I would thoroughly recommend before seeing the site in the daytime. You can visit the Port Arthur website for more info if you find yourself in that neck of the woods.
