Authorship
When you are researching with other people, including your supervisor, and writing multi-authored works, intellectual contribution must be considered.
In general terms, only persons who have made a significant intellectual contribution to the work should be included as authors, and the first author should be the person who wrote the work and contributed most of the intellectual content. It is not appropriate for persons to claim authorship solely because they obtained the funding for the project or provided data.
The Australian Code for the Responsible Conduct of Research recommends in Section 5.4 that all co-researchers (which includes you as a research degree student) should consider who will be included as authors, and in what order, at a very early stage of preparing the written work.
