Areas of Curtin were designed in accordance with the Radburn model of suburban design and public housing. In Australia, the Radburn model was used in the planning of some Canberra suburbs developed in the 1960s, in particular Charnwood, Curtin and Garran, and a small part of Hughes. These pockets of Radburn design have not seen the same anti-social and crime-related problems that have plagued similar areas in Western and South-Western Sydney, such as Mt Druitt.

The Canberra bushfires of 2003 destroyed four Curtin homes and caused damage to others. The Emergency Services Bureau, based in Curtin, which was the centre of command for the firefighting operation, came under threat itself when its roof caught fire.

The suburb celebrated the fifthieth anniversary of the arrival of its first residents in 2014. As part of that celebration, the Canberra & District Historical Society, which is headquartered at the shops, helped local residents to record oral histories of their memories. They can be accessed on a Web site called Curtin Living Memories. Residents subsequently compile and published a book on life in the suburb called, Curtin Turns 50.
