First we get this:-
Summary Miller report.
2007 Miller Report.
Then there's this:- Senate Inquiry into Pilot Training and Airline Safety Including the Transport Safety Investigation Amendment (Incident Reporting) Bill 2010.
18. With respect to CASA’s function in developing standards, effective rule-making needs to be based on principles of safety risk management. Safety risk management for the Regulator involves identifying hazards, assessing the safety risks of the consequences of those hazards and developing regulations that provide acceptable mitigation/control of the consequences of hazards.
19. In accordance with the provisions of the Transport Safety Investigation Act, the disclosure of information from ATSB investigations for purposes other than addressing identified safety issues within safety systems is limited – even to CASA – in the interests of preserving the free flow of information to the ATSB. If CASA is concerned to get additional information it can source the information separately in the majority of circumstances through its own processes. However, this is not as practicable with respect to accident and incident reports which the ATSB receives over 15 000 notifications in relation to each year.
20. For this reason the ATSB and CASA are presently considering ways in which CASA can obtain more open access to the ATSB accident and incident notification information, in order for CASA to enhance its ability to fulfil its functions under the Civil Aviation Act, without compromising confidentiality where it is required. Understandably, providing more open access necessitates the development of appropriate protective mechanisms governing CASA use of the information it obtains for certain regulatory purposes. In this respect, the ATSB and CASA are cooperating closely in the development of evolving ICAO standards affecting the disclosure of sensitive safety information
