Redhill is in the Port Pirie Regional Council local government area, the South Australian House of Assembly electoral district of Frome and the Australian House of Representatives Division of Grey.

Redhill was established in the late nineteenth century under the name of Broughton, with a hotel, blacksmith, general store and other businesses built within the township.

Several churches were also built in the township; a cemetery is on the town's south eastern outskirts.

The town now has a small museum opposite the Eureka Hotel, located in the former offices of the District Council of Redhill.

The Princes Highway bypasses the town with a petrol station situated between the road and the township.
