Hallett is a very small town on the main road to Adelaide if traveling south or to NSW and Broken Hill if traveling north. Hallett is quite close to a number of wind farms. There are some quite nice a d cute things about Hallett, not the least the very old shop, and the tribute to the merino sheep that was a year 2000 endeavour.
Hallett has significant history. Being situated on the Barrier Highway 32 kilometres (20 mi) north of Burra and 38 kilometres (24 mi) south-east of Jamestown, Hallett lies close to Goyder's Line, plotted in the nineteenth century by George Goyder, separating the land suitable for cropping from the land suitable for grazing.
Once a railhead for the local farming community, the town today features a store, gallery and the friendly Wildongoleechee Pub.
Hallett is the closest town to Mount Bryan East, birthplace of Sir Hubert Wilkins (1883 - 1958), perhaps the last modern explorer. Sir Hubert Wilkins birthplace and childhood home, Netfield, now restored as a historic site, is easily accessible from the renowned Mount Dare Driving Circuit between Hallett and Terowie.
