Historical Research

Historical research is fundamental to understanding the significance of a place. Our accredited public historians are highly skilled practitioners that have uncovered the history of thousands of heritage places throughout Australia. Using historical plans, maps, oral histories, and documents or photographs held in archives, libraries, museums and private collections they bring places and the past to life though history.

We can collect specific documents, research and document the history of your property, record oral history and present the material to you in a range of formats depending on your project.
