The other pad that the accident aircraft took off from is right beside the ticket booth so lot of machines come and go from that pad. Its an ease of convenience for those inside the park who have bought tickets, buy ticket - walk 20ft to the helicopter and take off rather than having to go outside the park and then over to the new facility.
That is a significant statement and a line of investigation that the ATSB will be following. Words like "ease of convenience" and "buy ticket - walk 20ft to the helicopter" all imply a commercial imperative ahead of the safe operation of the helicopter. What were the risk mitigators for operating from two sites? Did the Ops manual cover this? Were the pilots briefed on this? Were any non-operational staff involved in the decision to operate from that helipad? When was the decision made to operate from that helipad? What was the CP's role and was he under commercial pressure?
This investigation will be taking a good look at the organisational aspects of the accident and as a consequence it will not be finalised anything shorter than 18 months. The investigator in charge of this will not be working fulltime on this until completion. While they are obtaining the evidence for this they will probably have another five investigations they are responsible for.
