Exhibitions from overseas are valuable not just because they acquaint you at first hand with the scene elsewhere. They're also useful for appreciating how much you judge art on the basis of local knowledge. If you spend much time viewing Australian shows, you quickly develop a knowledge of the expressive scope and signature styles of each artist. To that extent, the work already makes sense.
Some themes travel better than others.
The strength lies entirely with themes that have nothing specifically to do with London. The best work transcends the town in its evocation of Western icons. Denise Webber's Clay imaginatively translates the chronophotography of Edwaeard Muybridge from the 19th century. His technical studies of locomotion sequentially parsed the movement of people and animals in rapidly repeated still exposures. Webber has strung the stills together to form a moving image, an unsettling combination of the scientific, the exotic and the voyeuristic.
