Quokka, I am now starting to doubt this incident,(ie the alleged near miss between a RFDS plane and a crop duster that ADSB would have prevented) happened at all.
Next week I will contact each RFDS branch and attempt to confirm the claim. It's interesting that you claim to be the controller involved (everyone check post 557) however you are not prepared to name the airport!
There may be people involved with the RFDS who do not understand risk management and therefore will allocate a large amount of finite resources to areas where the risk is small resulting in an under allocation of resources where the risks are higher!
In the meantime can anyone else shine some light on this particular incident?
