A good one you hear often is "All traffic XXX, YYY an IFR important jobby is doing a sector three entry for a 27 NDB"
Not sure where you would hear this "often", airline schedules don't allow for pilots to tool around for the hell of it. Do it often and expect a call into the office. More likely from an IFR important jobby 310 doing an IR.
Has it been ascertained whether an earlier, perhaps 30nm call was made on CTAF that perhaps wasn't heard (it is a large and busy CTAF)?
Was the request for position clarification from an aircraft that clearly was not a conflict (eg in the circuit at Lismore)?
