Course and features
The Spero River rises below Thirkell Hill on an unnamed range within the Southwest Conservation Area. The river flows generally north by west, joined by the Pery River and one minor tributary before reaching its mouth and emptying into Spero Bay, south east of Point Hibbs, eventually flowing into the Southern Ocean. The river descends 287 metres (942 ft) over its 29-kilometre (18 mi) course.
The river mouth is located on a walking track entitled the Hibbs Lagoon to Low Rocky Point, approximately 58 kilometres (36 mi), 12-days plus, along the south western coast of Tasmania that is considered the most difficult section of the coast.
Much of the course of the river is isolated with very limited direct contact with the outside world, however a Huon Pine timber venture in the 1930s and 1940s saw some level of activity in the area  and in the same era the closest council considered track making from Birchs Inlet on Macquarie Harbour
