Australian privacy commissioner Timothy Pilgrim is expected to today consult to Vodafone about the issue.
His office has the power to conduct an own-motion investigation, and even order that Vodafone pay compensation to affected customers. But the commission has to date yet to use that power.
Vodafone Australia, already sweating in the spotlight over complaints of ongoing network outages and congestion, now also faces having breach of privacy claims added to the class-action lawsuit planned in response to the outages.
Law firm PiperAlderman has revealed it will send letters out to the thousands of Vodafone customers which have registered an interest in joining the action, and will add claims to the suit if the respondents can provide details of privacy breaches.
Vodafone Australia in 2009 merged with Hutchison Australia's 3 to form Vodafone Hutchison Australia (VHA). But the Vodafone and 3 brands continue to operate independently.
