Families of four Australian Defence Force personnel killed in a 2023 MRH90 Taipan helicopter crash have launched a class action in the Federal Court. Multiple outlets report the action follows the deaths of four army aviators during a training exercise in the Whitsundays. The West Australian and PerthNow say the lawsuit is filed against the Commonwealth, and 7News Australia reports it is also directed at Airbus, with relatives alleging that failures contributed to the crash. ABC and other outlets describe the move as a class action brought by families of the deceased, seeking legal redress connected to the circumstances of the incident. The reports agree on the key elements: the crash involved an MRH90 Taipan helicopter, it occurred in 2023 during a training activity in the Whitsundays region, and it resulted in the deaths of four ADF personnel. While outlets differ on which defendants are named, they collectively state that the families are pursuing court proceedings through a class action related to alleged shortcomings leading up to the crash.
