Weiler and Blount's research in the United States, along with Cavanagh's in Canada, and Oram, for example, in the United Kingdom, have outlined the shifting perceptions of spinster teachers from the mid-nineteenth to midtwentieth century. 5 Continuing in this vein, this article focuses on the spinster teacher in Australia.Beginning with the introduction of mass compulsory schooling legislation in the 1870s, and using age and marital status as key categories of social difference, this article provides an overview of issues surrounding the 'woman teacher' through to the postwar baby boom. It shows how women teachers were increasingly differentiated according to location (country and city) and level of schooling (kindergarten, primary and secondary), and it also casts them as somewhat threatening to the gender order.Firstly, the article describes the processes by which teaching in both city and country
