accurate, a notable feat given the relatively limited knowledge of the local climate at the time it was surveyed. In December 2015, climate scientist Peter Hayman stated that the current "warming, drying trend" of South Australia's climate would definitely "put a downward shift on Goyder's Line" towards the south. Location 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. Agriculture is possible north of the line near the Murray River, only because of irrigation using water drawn from the river. When flying over the area, the distinct change in flora makes it possible to see the approximate path of Goyder's Line. Cultural significance Goyder's Line became a National Trust of Australia Heritage Icon in 2003. Other states have similar conditions where parts of a state are arable but other parts are suitable only for pastoral grazing; however, no other state has a surveyed line equivalent to Goyder's line.
