Previous Aboriginal Cultural Heritage Investigations

As with most parts of Australia, the study area would have been well known, if not utilised, by Aboriginal people for at least the past 30,000 years. The Port Phillip Bay region has evidence for this period of occupation at Keilor (Bowler 1976:63-65), and burial sites in the Maribyrnong and Werribee River Valley dating back 7,000 years (Mulvaney 1970; Coutts 1977, 1980). While slightly more favourable climatic conditions during the early Holocene period may have seen increased use of the region during this time, greatest use is most likely to have occurred during the past 5,000 years.

Like many parts of Victoria, the study area may have experienced population increases and reorganisations of social groupings due to a series of complex internal changes in society (Lourandos 1993).
