 Hi, my summary of the privacy implications is there on the screen that Australia has international obligations to provide an adequate protection against interference with privacy, which sounds grand but in fact our response is very piecemeal and very inconsistent. It comprises three different areas, privacy of information, privacy of communications which can be regarded as privacy from surveillance and personal privacy of the common law. So far as privacy of information is concerned that includes things like an image that can identify a person and again this Commonwealth Law is the state laws. At a Commonwealth level the law only applies to Commonwealth agencies so if you're a researcher with a Commonwealth agency those laws will apply or a private organization with an annual turnover of three million dollars or more. The laws that apply in the Commonwealth law are called the Australian Privacy Principles and they apply to things like the collection, the storage, the use and disclosure of personal information, those images. At a state level the states have enacted things called the information privacy principles, the IPPs that are similar to the APPs. As far as the, but as I say that only applies to personal information and that could be a person's image. As far as the common law is concerned well we're the only major Commonwealth, common law country that's pretty much the Commonwealth countries that don't have protection for personal privacy. The most we have is existing common law actions such as trespass, trespass to land, private uses which is an interference, an unreasonable interference with someone's property or in the case of disclosures something called a breach of confidence action. So in the case of a use of a drone you can have really two forms of interference with privacy. An unreasonable interference or invasion by intrusion and then the disclosure of the information that you collect which might be again those images but very limited remedies for people whose privacy is being intruded. For example trespass won't be committed if someone keeps the drone outside of someone's property line or if they fly above what's known as a reasonable user that might be above the rooftop and some height above that but above the level to the skies is not regarded as committing a trespass. When it comes to the surveillance laws we have eight jurisdictions of course in Australia three of those Queensland the ACT and Tasmania don't have visual surveillance laws so there's nothing there stopping drones from taking images of people. The other five jurisdictions do have visual surveillance laws but they're all inconsistent they're not uniform so for example the Victorian law doesn't apply to anything occurring outside of a building the South Australian law doesn't apply to anything in public so a very uneven landscape when it comes to privacy protection in Australia. Five law reform commission have inquiries have recommended that there be uniform laws but no government has yet enacted that those recommendations of having a statutory cause for action protecting privacy. I've left there on the screen an article there that if you're interested in further reading you can read that one there the dawn of the age of drones. So that's the situation when it comes to privacy in Australia a very uneven and not a very satisfactory situation at the moment.
