The ATSB would not know anything about investigating a helicopter accident, they probably did not even attend the site, they usually don't, even in a fatal they may not.
Most helicopter accident reports from the ATSB say NFI, not formally investigated or, NOI, no onsite investigation, and they don't understand helicopters at all.
What a strange thing to say, deeper. ATSB were there all day, and the investigation is continuing. You might notice the chap with "ATSB" on his hat in this photo?
As for the "boatshed": with a 20+kt southerly as on the day, departing to the north of the shed, there is often noticeable turbulence coming off the building. This picture is taken from just NE of the helipad (looking downriver to the SW), the departure would have been to the bottom right, with a left turn out to the right of the moorings on the centre right of the picture.
