Brett Button, the bus driver involved in one of Australia's deadliest crashes that claimed 10 lives and injured 25, emotionally testified in court, expressing deep remorse for his actions. During a Newcastle District Court hearing, the 59-year-old admitted to taking more than his prescribed dose of the opioid Tramadol before the accident, stating he could not forgive himself for causing such devastation. He described the incident as committing the 'ultimate sin' and expressed a desire to disappear, highlighting the profound regret he feels for the families affected. The court heard harrowing victim impact statements, with families detailing the irreversible damage caused by the crash. Judge Roy Ellis emphasized Button's obligation to ensure the safety of his passengers and noted his significant moral failure. Button faces 19 charges, including dangerous driving causing death, and has pleaded guilty to these offenses.
