The 'fair dealing' provisions of the Copyright Act do not apply to the use of someone else's work in your printed or online thesis. Unless your use is covered by an exception (such as criticism or review and insubstantial portions), or the duration of copyright has expired, you will need the copyright owner's permission to use their material in your thesis. Permission must also be sought for unpublished material such as manuscripts and letters, confidential information and material subject to a contractual arrangement.
As seeking copyright permission can be a lengthy process allow time for this and if necessary follow up your initial request with a reminder.
Although there are a number of exceptions to copyright, 'criticism or review', and 'insubstantial portions' are probably the most likely exceptions that cover the inclusion of other people's material in higher degree research theses. The Australian Copyright Council Information Sheet, Exceptions to copyright, is an up to date guide for further information.
Having said that, it is recommended that you seek permission to include any third party material (where someone else owns copyright) in your thesis.
For literary, dramatic, musical and artistic works, duration of copyright is currently until 70 years after the death of the creator. For other types of works including unpublished works, the duration may vary because of the type of work or due to historical changes in the Copyright Act. The Australian Copyright Council Information Sheet, Duration of Copyright details how to decide whether copyright has expired and tables the current rules.
If permission has been granted it is important that you adhere to the UWA Research Integrity policy* (which operationalises the principles and practices of the Australian Code for the Responsible Conduct of Research at UWA). Ensure that you:
