From a handful of practitioners in the '70s, there are now more than 250 commercially based archaeologists in Australia. Again in Victoria, one of the first to establish was du Cros and associates (later absorbed by Biosis Research, renamed Biosis Pty Ltd in 2012). The Australian Association of Consulting Archaeologist Inc. (AACAI) is the professional body established in 1979 with presently about 50 full members. In New South Wales, companies such as Casey and Lowe and GML have specialised in large scale historical archaeological salvage.
