Without disrespect to the deceased, ATSB lodged a notice on their website on Sunday the 31st December 2017 for VH-NOO. It is Sunday 21st 2018 and nothing has been raised for this case yet.
The reality is that the general public would be googling the Sydney crash and looking for answers along with the news covering it heavily so the ATSB needs to be seen to be doing something.
The ATSB Facebook page provides information about this accident. Updated Sunday 21st 2018.
