Actually, I was amazed to learn from Twitter today that an Australian cockatoo was given to an Arab Prince or someone like that in the 13th century, meaning that trade with Australian Aborigines, or contact at least, has been happening for a very long time. So much for Terra Nullius.

At the site is an information sign, informing readers that is was one of the earliest areas of European occupation. John Batman bought the the land that went on to become Melbourne. Batman built a seven room timber home on the site. By 1838 it had become Miss Cook's Seminary for Ladies, a boarding school, attended by Batman's own three daughters. In the 1850s more substantial brick and timber buildings were constructed and were occupied by various businesses over many years. As far as I know, there was nothing about the buildings demolished that was historic or even nice.
