Goyder's Line

After traversing an estimated 3200 km on horseback (not including the Eyre Peninsula) in November 1865, he submitted his report and map to the colonial government on 6 December.

[2] Ample rains fell in most years between 1867 and 1875, prompting farmers to ignore Goyder's report and settle in the north, starting farms and planting crops.

The line has proven highly accurate, a notable feat given the relatively limited knowledge of the local climate at the time it was surveyed.

[5] Goyder's Line starts on the west coast near Ceduna and runs south-east across the Eyre Peninsula to strike Spencer Gulf near Arno Bay.

It continues from near Moonta north to Crystal Brook and Orroroo, then south-east past Peterborough and Burra to the Victorian border near Pinnaroo, crossing the Murray River south of Blanchetown.
