The TN A300B4's were fitted with 269 seats at delivery. The original 5 AN B767-200's were fitted with 211 seats. The B767-200 was a piece of cake between SYD-PER whereas the A300B4 struggled with fuel calls at ADL.
Ansett found it easier to get target load factor with the smaller B767-200 and the aircraft was a frequent visitor to places such as ASP, CNS, DRW, HBA, HTI, LST and OOL.
Ps. I do not believe AN ever got a MTOW from MEL to PER.
