Like the United States and the EU, the concept of Fair Dealing, similar to Fair Use in the States, is permitted in Australia. So it seems that using a newspaper image grabbed from a site for our research purposes on WikiTree is permissible as long as you cite the source of where the image is found.
The main exceptions to copyright infringement in Australia come under the general heading fair dealing. Fair dealing is comparable to the United States' fair use; it is a use of a work specifically recognised as not being a copyright violation. In order to be a fair dealing under Australian law a use must fall within a range of specific purposes. These purposes vary by type of work, but the possibilities are:
- review or criticism
- research or study
- judicial proceedings or professional legal advice
- parody or satire (added by the Copyright Amendment Act 2006)
In order for a certain use to be a fair dealing, it must fall within one of these purposes and must also be 'fair'. What is fair will depend on all the circumstances, including the nature of the work, the nature of the use and the effect of the use on any commercial market for the work.
