The question was "legally" does every operator have to have a procedure based on the findings of this investigation. My opinion was no. The reason: the ATSB is an independent investigative agency. Industry and government are responsible for policy change, not the ATSB. The ATSB makes findings. My take on the findings in this case were that crew distraction, weather, night, and the unusual arrangement of the runway having Ordinance Loading Areas and associated lighting at the threshold, were the major causal factors, and that not having a procedure was listed as a 'Minor safety issue'. The aircraft operator made a decision implement changes to procedures based on the incident, but that does not mean that all operators are legally required to do so.
