Five people have been badly injured in a horror crash between a bus and car in southwest Sydney, including a 13-year-old girl and woman in her 50s rushed to hospital in a critical condition. The two vehicles collided in the wet weather on Memorial Ave in Liverpool on Saturday morning, with NSW Ambulance saying it was “mayhem” when paramedics arrived on the scene just after 11am. The teenager and woman in the car were taken to Liverpool Hospital, while the male driver, also in his 50s, was transported to the hospital in a stable condition.
