Such legislation also generally restricts publishing or ‘showing’ unauthorised recordings that were obtained by using such a listening device. In all states and territories, there is a specific prohibition on the use of a listening device (such as a mobile phone or hidden film camera) to record a private conversation without the consent of the participants to that conversation. There is legislation in each state and territory concerning surveillance and listening devices (which would including mobile recording devices such as mobile phones), intended to protect peoples’ private activities and conversations. Those issues arise because people can easily be recorded on such devices without their knowledge. However there are some important legal matters that are particularly relevant to the making of films on a smartphone or surveillance device. Generally, the same legal issues need to be considered whether your film is made on a phone, or any more traditional equipment. Making short films or videos using mobile phone technology is increasingly common.
