Prelim report not giving much away. Going off eyewitness reports.

I find this a bit strange. 28 Takeoff and going towards the training area, is a upwind departure with a left turn toward the training area a few miles after takeoff. Why conduct a low level right hand turn? I mean there is power lines on crosswind. I don't really see any real need for a field departure off the crosswind circuit with a abundance of hazards vs a straight out departure with little in the way off hazards (well no tall power towers anyway). It appears they did this again on the touch and go fatal circuit. A low level right hand turn will line you up with that road where they ended up, if under twin power.
How often is 28 used? Every time I pass overhead inbound to Cairns on a heavy, it is always 10. Which is why we listen in as the steps are fairly close.
Once airborne, the pilot broadcast that they were ‘making a low-level right-hand turn and then climbing up to not above 4,500 [feet] for the south-west training area.’
