How long does copyright last in Australia?

As with other aspects of copyright, duration of copyright varies between countries. If you want to use material published in other countries Wikipedia's List of countries' copyright lengths table provides a good starting point.

In Australia, copyright in published works generally lasts for the life of the author plus 70 years. The duration of copyright in subject matter other than works (films and sound recordings for example) is more variable, but generally is 70 years from the end of the year of first publication. There are variations from these general rules. Before 1 January 2005, the term of copyright in Australia was life of the author plus 50 years for published works, and 50 years after publication for audiovisual items. The extended term of 70 years applies only to material that was still in copyright on 1 January 2005. If the copyright had expired by that date, it stays expired. Crown Copyright refers to material made or first published by state, territory or commonwealth government. The term of copyright for these works is generally 50 years after date made.
