Giles Corner (formerly Giles' Corner) (Postcode 5411) is the name of the intersection of Main North Road (now called Horrocks Highway) and the Barrier Highway, halfway between the towns of Tarlee and Rhynie. The Barrier Highway branches off from Horrocks Highway at this location, heading north towards Riverton, Burra and eventually Broken Hill. Horrocks Highway continues in a northerly direction, on to the towns of Rhynie, Auburn and Clare. There is also an unsealed back road starting just north of the junction which heads west and ends at the road between Balaklava and Owen, approximately 20 kilometres away.
