For information on preparing for hearings and conferences, you can refer to the Fair Work Commission's Unfair dismissal – guide 7: Preparing for a conference or hearing, which is available on the About hearings & conferences page of the Commission's website.
The Commission's website also has downloadable documents to help parties prepare for an unfair dismissal conference or hearing, and gather information that will be relevant to the member deciding whether or not the dismissal was unfair.
