Telstra is making money by on-selling location data from its customers' mobile phones in similar deals to a partnership with the Bureau of Statistics that caused a public backlash last week.

The Australian Bureau of Statistics came under fire for partnering with the telco for a study in 2016, which used mobile phone data showing how many people were in particular suburbs hour by hour.

Similar data is now available for a fee, after the Location Insights program was quietly launched by the telco in July 2016. The Australian Bureau of Statistics was the first licensee under the program, but has not used Telstra's Location Insights since then.

Data available to Telstra's clients can be broken down into 15 minute increments, and demographics broken down by age groups and gender. The smallest geographic areas available for analysis are the same as the Australian Bureau of Statistics' smallest statistical area, which have an average population of 400 people and could have as few as 200 people.
