The Privacy Amendment (Enhancing Privacy Protection) Act 2012 is an amending Act. It does not set up a separate, standalone privacy code for businesses. Instead, it changes the Privacy Act 1988 and also makes related amendments to a large number of other Commonwealth laws.
That matters in practice because if your business is checking its privacy obligations, you should not read this Act in isolation. The operative rules for most businesses sit in the Privacy Act 1988 as amended, including the Australian Privacy Principles, the credit reporting provisions and the privacy code framework.
The Act is structured through schedules. Schedule 1 deals with the Australian Privacy Principles. Schedule 2 deals with credit reporting. Schedule 3 deals with privacy codes. Schedule 4 makes other amendments to the Privacy Act 1988. Schedule 5 amends other Acts. Schedule 6 contains application, transitional and savings provisions.
