Facebook could face a hefty compensation bill in Australia after a leading litigation funder lodged a complaint with the country's privacy regulator over users' personal data shared with a British political consultancy. Under Australian law, all organisations must take "reasonable steps" to ensure personal information is held securely and IMF Bentham has teamed up with a major law firm to lodge a complaint with the Office of the Australian Information Commissioner (OAIO). IMF said in a statement late Tuesday it was seeking "compensation for Facebook users arising from Facebook's alleged breaches of the Australian Privacy Principles contained in the Privacy Act 1988". In its statement, IMF Bentham said it appeared Facebook learned of the breach in late 2015, but failed to tell users about it until this year. IMF investment manager Nathan Landis told The Australian newspaper most awards for privacy breaches ranged between Aus$1,000 and Aus$10,000 (US$750-US$7,500). Facebook did not directly comment on the IMF Bentham action but a spokesperson told AFP Wednesday: "We are fully cooperating with the investigation currently underway by the Australian Privacy Commissioner.
