A number of Warialda citizens met in June 1850 in Geddes store to consider the health requirements of the town.   A public meeting was organised and held on 4 July to choose a resident medical officer and to launch an appeal for a new hospital.  An application was made to the Colonial Secretary for a grant of land to build a hospital and doctor’s residence.    Warialda raised the necessary funds and the grant was made.  The first hospital was opened in 1862 in Hope Street, section 54, allotments 5 and 6.

In 1884 a new hospital site was dedicated.  Tenders for construction of the hospital were called on 17 November 1894.  Designed by Sydney architect John Kirkpatrick, the building was completed by B.B. Kinnew.  The hospital opened in July 1895 and by 1897 had five wards- male, female, private as well as a male and female fever wards.  This building still stands beside the brick hospital erected in the 1970s.

It was in November 1897 that tenders were called for pulling down and re-erecting the building known as the Doctor’s Old Residence at Warialda.

The secretary called tenders for additions to the Warialda Hospital in December 1901.  In July 1904 J. Keenan refused to sign the tender for construction of two rooms at the hospital and fresh tenders were called to close on 1 August.  Again in June 1905, W.L. Davis the Hon. Secretary, called tenders for construction of two rooms at the hospital.

The partnership between Drs. Holmes and Blue at the hospital was dissolved in October 1905.

In June 1921 plans were announced for new nurses quarters at the hospital.  A special meeting of the Hospital Committee was held on Thursday 11 May 1922 to receive the plans of the proposed nurse’s quarters prepared by O’Connor and Ogilvie of Inverell.  To be erected on the western side of the main building, the plans included new quarters, additions to the isolation block and alterations to the rooms to be converted into private wards.  It was not until September that O’Connor and Ogilvie called tenders for work at the hospital.  

By the end of 1932, the Warialda Branch of the Country Women’s Association had accumulated funds for erecting a hostel in Warialda.  The Branch changed its mind and offered its funds to the Hospital Board for the construction of a Maternity Unit at the Hospital.  In November 1933 a Public Works Officer set out pegs for the maternity unit and tenders for construction of the unit were called in January 1934.  By December the unit had been in use for some months but ‘the official opening has not yet taken place owing to difference between the contractor and the Department in connection with some minor alterations’.  Mrs B.M. Capel, the former president of the C.W.A. assisted by president Mrs J.A. McGregor on 19 January 1935, finally opened the Jessie Carlyon Maternity Unit.  Mrs Carlyon had donated ₤250 to the funds of the C.W.A. and the branch accumulated an additional ₤550.  Consequently the Minister for Public Health agreed to find the additional ₤280 and the cost of furnishing and equipping the unit, ₤300.  

Architect Wallace from the Public Works Department and with the assistance of the Hospital Board Directors, inspected the hospital buildings in July 1934 with a view of preparing plans and estimates for additions to the nurses’ quarters and extensions of the eastern ward.  The Warialda Standard, 28 August 1952 announced additions to the nurses home and hospital.

In 1939 local businessman Colin Pyrke, organised a programme of beautification in front of the new hospital.  In June 1939 the Warialda Standard reported on extensive beautification works completed in the hospital grounds by volunteers and Shire employees and contractors.  Lorries and horse scoops were used to move gravel and earth to construct the roadway.  Initial steps were taken to form a garden and construct a galvanised piping and cyclone wire fence.  These working bees continued on for several weeks.  On the Long Street side of the driveway, Roy Balston built the rock walls to enclose the lawns and gardens.

The centenary of the Warialda Hospital was celebrated in October 1995.  A history of the hospital was written by M. Williamson and published by the Warialda Health Service, Local Advisory Board, that year.
