The Aussies are flying the F-111C and F-111G (former EF-111A) now, and they know how to use them!
Looks like the F-111 may have inspired the B-1B design. I worked for Rockwell International on the B-1B production program and the F-111 was the chase plane used on the Maiden flight of ship 1 of the B-1B program.
You are correct the A-6E Intruder is no match for the EF-111, then again the Intruder is/was a Medium Attack Bomber not a specialized platform for EW... I believe you meant the EA-6B Prowler which is an Electronic Warfare bird.
Gs are former F-111As not former Ravens. The EF-111A was still in service when the Aussies obtained their 15 Gs from AMARC. Those Gs were upgraded to Cs before delivery down under.
