I wonder if the accident pilot had applied for a CASA licence? No written exams or flight test to do, just fill in the form. Nautilus advertised for ground crew back in March on a salary of $50K (and again on SEEK only 4 days ago) - the timing seems to fit that they hired this pilot in response to that vacancy. I suspect the back-story here might have something to do with what happened and that alcohol was the catalyst.
