So, from what I have ascertained from the article and this thread, the pilot had 400 litres of mogas in a 6 seater Warrior. Should be a no brainer for the ATSB.
No you are entirely wrong in your summation! The great aviation oracle LeadSled has spoken after leaving crumbs for the lesser mortals to follow. The real reason this accident occurred was the absence of a north-south runway! Forget the issue of fuel starvation/exhaustion and the "big picture" of ineffective training in fuel management, this accident happened because of a runway that no longer existed. The ATSB will definitely be hammered for not following that line of investigation.
