In 1954 Dame Enid Lyons, the first woman elected to the Australian House of Representatives, argued that radio had 'created a bigger revolution in the life of a woman than anything that has happened any time' as it brought the public sphere into the home and women into the public sphere. Taking this claim as its starting point, Sound Citizens examines how a cohort of professional women broadcasters, activists and politicians used radio to contribute to the public sphere and improve women's status in Australia from the introduction of radio in 1923 until the introduction of television in 1956. This book reveals a much broader and more complex history of women's contributions to Australian broadcasting than has been previously acknowledged.
