In addressing the concern, the letter asks that Google reveal information on what other types of information it is collecting, the purpose behind it, and how the company intends to "use, store and make available this information".

A spokesperson for Google Australia refused to comment on the issue, and Google globally is yet to comment on privacy concerns raised both here and abroad.

While a new concern for the organisations behind the letter, it isn't the first time that Google's Street View program has been criticised. The program's inception lead individuals, advocacy groups, councils and even governments to complain that the mere act of taking such extensive photography of public streets was a breach of privacy.

Google's other geolocation offerings, Maps and Earth, have also been cause for concern among governments and companies who wish certain buildings and geographies to remain secret. Street View is available as a feature in both solutions.
