Middle Ridge Shire Council was established on 22 May 1880.
Under "The Local Authorities Act 1902", the primary function of Shire Councils was to provide such public services and amenities as parks and reserves, cemeteries, libraries and recreational facilities, water and sanitation services, roads, bridges, wharves, street lighting, public health services (such as immunisations), licences and registrations for businesses, markets and animals, town planning, and the control of noxious weeds and other pests.
The Council was also responsible for administering the Local Fund, and for valuing properties within the Shire for the purpose of determining and collecting rates.
The Council could pass by-laws regarding all matters within its jurisdiction. All such by-laws required the assent of the Governor-in-Council.
The Shire Council included a chairman, town clerk and a number of other members. From time to time, the Council could appoint committees for special or general purposes. Council also appointed its own officers, who were paid from the Local Fund.
Each year the Minister appointed an independent auditor to review the financial statements of the Council. The Council submitted an annual Statement of Revenue and Expenditure to the Minister, which was published in the Government Gazette.
Middle Ridge Shire was abolished on 23 February 1917 and part was included in the City of Toowoomba and part in the Shire of Drayton.
