Only one on a stick, I think, the one for ARDU. And yes, US regulations for the airframes and TF30 engines are very strict.
I believe the following is the disposal plan:
A8-125, first RAAF F-111C, for RAAF Museum Point Cook (which already has an F-111G).
A8-126, first RAAF F-111C to fly with Aussie crew, and RF-111C protoype, for RAAF Heritage Centre Amberley.
A8-132, AUP prototype and ARDU test vehicle, for ARDU at RAAF Edinburgh.
A8-138, Pave Tack prototype, gate guard at RAAF Amberley with Canberra A84-201.
A static aircraft at the farewell was A8-113, an ex-USAF F-111A, which as 67-0113 flew the last F-111 combat mission in southeast Asia. I heard that this had been offered to the USAF Museum, but they already had an F-111E.
