Noted here on 10th Nov (a local bank holiday so no based a/c out) were 5 Airbus 330MRTTs:
A39-001/747/EC-330 for RAAF
A39-002/951/EC-333 for RAAF
A39-003/969/EC-334 for RAAF
ZZ331/1046/EC-337 for RAF
the last a/c was marked EC-332 which would make it the long term wfu example (although I did note it marked "Royal Air Force")
Also here was Brazilian Air Force P3-AM FAB7203 (formerly 152140)
