Western Australian reports can be sourced from different locations, depending on the date:
There is an ongoing copyright dispute over the Western Australian reports between 1959-1982, so they are not available online until this is resolved.
Sometimes you will need to search full text databases of court decisions to find cases on a topic. This is particularly important for WA decisions which might not get "noticed" by publishers who produce indexes such as the Digest and CaseBase. Most WA decisions are never published in a report series, and remain forever unreported.
There are many online collections of Australian superior court unreported judgments.
Before searching, you will need to turn your research topic into a search string. For more information, see:
