What happened
The incident occurred while the aircraft was traversing Bass Strait. The four engine plane, identified by the name 'Miss Hobart', went missing approximately 16 kilometers off the coast of Wilsons Promontory National Park. Search and rescue teams conducted operations in the area and discovered scattered debris along with an oil slick on the water's surface roughly one day after the disappearance. Despite these findings, no remains of the eleven occupants were ever recovered.
The flight crew consisted of two pilots: Captain Victor C. Holyman, who was also a co-founder of the airline, and Captain Gilbert Jenkins. The specific circumstances leading to the crash remained unknown at the time of the report.
Findings
Official investigations concluded that the exact cause of the accident could not be determined. However, the investigative commission issued recommendations regarding operational procedures. Specifically, they advised against changing pilots in an aircraft while it was in flight. This recommendation stemmed from a theory suggesting that a loss of control might have resulted from such a handover action by the crew.
