"In Australia, the Human Rights and Equal Opportunity Commission specifically lists the display of pin-ups as an example of sexually harassing behaviour. While sexual harassment legislation in both Australia and the United States covers sites including workplaces and educational institutions, such legislation has not been designed to include sexual harassment occurring in public space. This article will explore the reality that outdoor advertisements on public display are visually very similar to sexually harassing pin-ups, as will be demonstrated through references to examples collected as part of a year long study of outdoor advertising in Melbourne, Australia. Because of the visual similarities between outdoor advertising and, for example, pin-ups which are prohibited in sites such as workplaces, this article suggests that both media should be critiqued in the exact same manner. This article argues that the specific elements that make sexual harassment inappropriate in the workplace – i.e., the captive environment that is created whereby exposure to sexual images is unavoidable – is a situation replicated in public space with a person utilising space being held captive in a similar manner. Similarly, this article will explore the manner in which pin-ups masculinise a workplace in the same way that sexist outdoor advertisements masculinise public space. The usefulness, limitations and feasibility of the application of sexual harassment discussions to sexist outdoor advertisements will also be considered."
