If you search the Australian aircraft register, of the small number of helicopters with "NSW Helicopters Pty Ltd" as the Registered Operator, VH-ZMF is the only Bell 206L-1 and AustAirData shows it in scheme as seen in image of door posted by KRviator. A Polish aviation magazine website is indicating the crashed helicopter is VH-ZMF but not sure if they managed to get the information first hand from somewhere, or also by the above process. I replayed aircraft movements in the area via FlightRadar24 and the NSW Police Bell 412 made repeated passes and orbits over the scene, perhaps to gather information to support ATSB accident investigation??
