The shire, administered from the town of Ingham, covers an area of 2,807 square kilometres (1,083.8 sq mi), and has existed since its creation on 11 November 1879 as one of 74 divisions around Queensland under the Divisional Boards Act 1879.
The council consists of a mayor plus six councillors, each of whom represents the entire Shire.
Hinchinbrook was one of the few shires outside of remote areas in Queensland not to be affected by amalgamations in 2007–2008.
It was considered for amalgamation into the Cassowary Coast Region with Cardwell and Johnstone, but the Local Government Commissioners accepted arguments by the council that there was no significant community of interest between the three, that amalgamation would not improve financial sustainability and that the resulting council would have a large north-south distance which would impact upon economies of scale.
