The Privacy Act 1988 is an Australian law dealing with privacy. Section 14 of the Act stipulates a number of privacy rights known as the Information Privacy Principles (IPPs). These principles apply to Australian Government and Australian Capital Territory agencies or private sector organisations contracted to these governments, as well as to organisations and small businesses who provide a health service. The principles govern when and how personal information can be collected by these government agencies. Information can only be collected if it is relevant to the agencies' functions. Upon this collection, that law mandates that Australians have the right to know why information about them is being acquired and who will see the information. Those in charge of storing the information have obligations to ensure such information is neither lost nor exploited. An Australian will also have the right to access the information unless this is specifically prohibited by law.
The Privacy Act was amended in 2000 to cover the private sector. Schedule 3 of the Privacy Act sets out a significantly different set of privacy principles (the National Privacy Principles) which apply to private sector organisations (including not for profit organisations) with a turnover exceeding three million dollars, other than health service providers or traders in personal information. These principles extend to the transfer of personal information out of Australia.
Privacy principles that are substantially the same as the NPPs are also included in the legislation applying to the public sectors of some Australian States and Territories, namely the Information Privacy Act 2000 (Victoria), Information Act 2002 (Northern Territory), and Personal Information Protection Act 2004 (Tasmania).
Australia's privacy principles, both IPPs and NPPs, depend upon the meaning of "personal information" (as defined in Privacy Act 1988 s6). This term has not yet been interpreted in a restrictive way as has been "personal data" in the UK Durant case.
The Privacy Act creates an Office of the Privacy Commissioner and a Privacy Commissioner in Australia. Section 36 of the Act states that Australians may appeal to this Commissioner if they feel their privacy rights have been compromised, unless the privacy was violated by an organisation that has its own dispute resolution mechanisms under an approved Privacy Code. The Commissioner, who may decide to investigate complaints and in some cases must investigate, can under section 44 obtain relevant evidence from other people. There is no appeal to a Court or Tribunal against decisions of the Commissioner except in very limited circumstances. Section 45 of the Privacy Act allows the Commissioner to interview the people themselves, and the people might have to swear an oath to tell the truth. Anyone who fails to answer the Commissioner may be subject to a fine of up to $2,000 and/or year-long imprisonment (under section 65). Under section 64 of the Privacy Act, the Commissioner is also given immunity against any lawsuits that he or she might be subjected to for the carrying out of their duties.
