There are really only 2 questions that need to be answered:
Were they both IFR?
Were they in class G airspace?

If the answer to both is yes, then this is the Australian system Working As Designed.

We know aircraft in IMC cannot adequately self separate - that is why ATC was invented. We get away with it in Australia most of the time because IFR traffic is relatively low. We have rejected Class E (radar or procedural) designed to prevent this type of accident.
We knew the risk was there. We knew a collision between IFR aircraft in Class G would happen eventually. We know it will happen again eventually if the current system is maintained long enough.

We also know the solution: Class E airspace. Or perhaps these days a technology solution would be appropriate - make some form of TCAS mandatory for IFR aircraft.

A 3 year inquiry might find something the pilots did or didn't do that might have prevented the accident. But that would be a distraction. The real issue is we have IFR without ATC separation, and that means collisions will occur.
