At one end of the tunnel, closest the Gallery of First Australians, is a small metallic room. From the front it looks like the armour of an infamous Australian criminal Ned Kelly. The room is actually a camera obscura, a late Renaissance optical tool that purported to offer `objective vision' - everything this landscape is not. Once inside the camera, visitors can appreciate an upside-down image of the outside world and in this sense they are not only occupying the space of the criminal, but also the space of their own heads, as Rene Descartes would have it.

X

The map is an official document, a kind of social contract and so it bears various written signatures. Edmund Barton, Australia's first Prime Minister's signature is written on the end of a large red `X'. It is uncommon knowledge that many Aboriginal people signed (and still do sign) documents with an X. The X is a sign made under duress by a party who could often neither read nor write. Another signature is the word `Australia'. It is written very large, half in and half out of the water at the northern end of the garden. The word is written in reverse, as if held in a reflection. The word has been copied from a five dollar note and, as it scribbles its way across the whole width of the garden, one is reminded of Marcus Clarke's quip that in Australia nature seemed to learning to write. Nearby in the water is a fallen dead tree and a flood gauge.
