From the Australian Privacy Foundation:
Means for computing the location of a computing device have matured rapidly recently, and include GPS, Wifi, and triangulation within mobile phone cells. These techniques have enabled Location-Based Services (LBS) to be created. Many LBS are proving attractive to users of mobile devices such as smartphones and tablets.
Researchers and privacy advocates have long warned about the dangers of person location and tracking. During April 2011, the public became aware that location data was being gathered with much greater intensity, was being retained longer, was being stored in accessible places, and was being used for more purposes, than consumers had previously realised. Location data is creating risks that consumers had not previously appreciated.
This document summarises the APF’s policy in relation to the use of positional data relating to mobile devices as a means of locating and tracking the individuals carrying them. The scope of this Statement does not extend to other privacy issues such as use of positional data to collect information about third parties.
