There were three Australian crashes that I know of. All crashes were due to mechanical failure  of the aircraft. I thought there was a 4th crash at YBBN in 1954, with brake failure during a landing  of a TAA training flight. I cannot find any info on it. 
 VH-TVC at Sydney Airport 1961, VH-RMI at Winton (qld) 1966, VH-RMQ at Pt. Headland 1968.
