Definitions vary. In southern Australia autumn arrives with seven consecutive days under 18-degrees Celsius, and cold nights. Last year (2016) this occurred in May. This year it again does not look as though it is going to happen in April. Garden guides keep their standard planting timetables, out of synch with the changing patterns of warm and cold. The Wurundjeri identified March as the Eel Season and April to August as the Wombat Season. They caught eels in “weirs of stone and woven funnels”, mussels and fish, along the Birrarung. Birrarung itself means River of Mists. Mellow fruitfulness was anticipated.
