Benambran orogeny, a mountain-building event in eastern Australia during Late Ordovician time (the Ordovician Period began about 488 million years ago and ended about 444 million years ago). The uplift and deformation produced a tectonic ridge that separated the Tasman Geosyncline into an eastern and western belt, extending from Tasmania to northern New South Wales.
