Governance Rockhampton is governed by the Rockhampton Regional Council. The Council consists of a mayor and seven councillors. The Mayor is elected by the public, and the Councillors are elected from seven single-member divisions using an optional preferential voting system. Elections are held every four years. Tony Williams is the current mayor after the 2021 mayoral by-election following the resignation of long time mayor Margaret Strelow. Margaret Strelow won the mayoral elections in 2013, 2016 and March 2020. Strelow had also served as Mayor of the former City of Rockhampton from 2000 to 2008. The present Rockhampton Regional Council area was formed as a result of the 2008 amalgamation of four local government areas. These were the original City of Rockhampton which comprised most of the Rockhampton metropolitan area, the Shire of Fitzroy comprising Gracemere and surrounding districts, and the Shire of Mount Morgan around the town of Mount Morgan itself. The fourth local government area was the Shire of Livingstone which comprised the adjacent coastal towns and hinterland to the east and north of Rockhampton as well as some outlying Rockhampton suburbs. However, Livingstone Shire de-amalgamated from Rockhampton Region in 2014 following a referendum. Before the 2008 amalgamation, the City of Rockhampton had a population of approximately 74,530, Fitzroy Shire approximately 11,357, and Mount Morgan Shire approximately 2,925 people. Proposed boundary changes between Rockhampton Regional Council and Livingstone Shire Council are under review by the Local Government Change Commission. The changes relate to three suburbs contiguous with Rockhampton City which are presently part of Livingstone Shire. The proposed changes will affect 1170 properties in the suburbs of Glenlee, Rockyview, and Glendale.
