The QAS class action proceedings were initially brought in the Supreme Court of Queensland, on the basis that the Supreme Court has jurisdiction to hear the class action. The Defendants have contested this, arguing that the class action should be heard by the Queensland Industrial Relations Commission (QIRC).
On 25 July 2025, Justice Treston of the Supreme Court of Queensland determined that the QAS class action should be heard by the QIRC instead of the Supreme Court. On 21 November 2025, Sibley Lawyers appealed this decision to the Queensland Court of Appeal. On 21 November 2025, a hearing took place in the Qld Court of Appeal. The decision is reserved, and Sibley Lawyers is still awaiting the outcome.
