Lake Mungo, in New South Wales, is the home of the first known people in this country. Here, the oldest known evidence of Aboriginal people in Australia has been found. Because of its importance, it is a site which everyone should know about. To give us a feeling for Lake Mungo, Billy Reid, the illustrator of The Aboriginal Health Worker and The Aboriginal Child at School, came with me on a trip. We travelled west to the Darling River (whose Aboriginal name is Calewatta), and then south-east to Lake Mungo itself. Billy made wonderful drawings to represent the deeds and everyday life of those people. This can be reconstructed from the fossil evidence found at Lake Mungo. He has also drawn some scenes of life along the banks of the Calewatta - the river which is Billy’s own home. He hails from Bourke.
