Colonial Secretary's Office

The records of the Colonial Secretary's Office held at the State Records Office forms a major historical resource for research into Western Australia in the 1800s.

The Colonial Secretary's Office (CSO) originated with the appointment of Peter Broun as first Colonial Secretary on 30 December 1828. 

The CSO was established as the chief administrative office for the new Colony with the Colonial Secretary responsible for conducting the business of the Governor with the various government departments of the day as well as with the Colonists, collectively and individually.

The Colonial Secretary was a member of both the Executive and Legislative Councils from their formation in 1832. Following the granting of self-government in 1890, the position of Colonial Secretary was held by a Minister, with the Under Secretary becoming the administrative head of the department from that date.

The CSO was responsible for a variety of functions including customs, post offices, shipping, harbours, prisons and oversight of Aboriginal people. The Colonial Secretary dealt directly with England in matters concerning the Colony.

After Federation in  1901, the Office of the Colonial Secretary continued, although the scope of its functions were reduced as many of the CSO's responsibilities passed to the Commonwealth and State Governments. In 1924, the CSO was renamed the Chief Secretary's Department and the Minister in charge was titled the Chief Secretary. By 1980, its responsibilities had been limited to prisons, astronomical services, Registrar General of Births, Deaths and Marriages and the Correspondence Despatch Office and it ceased to exist as a separate department in 1983.
