Tamar Valley Geology Determining the First Peoples Occupation of Northern Van Diemen’s Land

Ian Pattie, November 2020


The forces of nature – volcanic, glacial, fault and the like – lay down a rough-hewn sculpture upon which other weathering forces produce a landscape for the evolution of flora and fauna. In Tasmania, the evolution of millions of years became more complex about 40 000 years ago with the advent of the First People of this land.

Accepting huge portions of the geological backdrop, the First People set about managing the environment to meet their needs. The rivers and valleys, the high country and the treed plains were accepted and adapted and features within the environment were brought into ceremony as required.

Britain was the world’s naval power, the coming industrial power, the greatest empire builders and affectionately described amongst themselves as the chosen people and the Protestant Protectors.

Tamar Valley Geology and British Settlement

British settlements, based on the traditions of British farming and shipping, needed arable land and protected anchorages for long-term survival. Well-watered farmland was not to be found easily near the mouth of the Tamar, near York Town or George Town, where the best port facilities were available. In contrast, good port facilities were not to be found at the head of the Tamar where well-watered farmland was available.

It is tempting to apply modern terms like ‘sustainability’ to Indigenous practice however the key to understanding First People’s attachment to country is adequacy.
First Peoples did not expend energy on wasted accumulation but on a vast Estate that provided the needs of a robust population using minimal exertion. “It depended on preferring to reduce rather than increase material wants.”
