Not quite true, its more whether you are found to be operating in a manner that could create a collision hazard. So you can be "too close" to another aircraft, but not touching it, if found to be creating a collision risk. However it is true that there is no stipulated separation, however neither is there in IMC, ATC have separation standard but OCTA aircraft can pass each other at any distance greater than what would be considered a collision hazard.
Be more than embarrassing if what happened at Caboolture happens at a CTAFed Class D.
Do they think it can't happen?
It almost happened at Albury between a PA28 and an ATR. Avoidance was triggered by TCAS, and not the control service.
