A great many papers have been written about the distribution of backed artefacts in Australia. Much of the debate has centered on whether there is a northern limit to backed artefact distribution or whether their apparent absence from the northern areas was a product of a lack of knowledge about assemblages in the north. A gradual northward creep in the the known location of backed artefacts, and hence in the infered northern boundary, has continued over the last decade and suggests that our information on backed artefact distributions was limited.
