The Three sisters to this A/C (TBE,TBG,DVN) are all C310R and all perform differently, ranging from rotate speed to leave the runway to climb speed on two engines and CHT's at/below redline. One will fly 10kts faster than another in the cruise. On a medium sector (eg;YMgd-Ypdn) one will arrive 5-8mins quicker. cruise climb one will climb at 500fpm the other will just manage 300-350fpm. So even though they are the same aircraft and proabaly built within a few months/year of each other they aren't the same.
Not sure if you are aware, there is another aircraft in the area of the crash from a few years ago. (Maybe 2007?) A Beech Bonanza going to the TIWI Is footy grand Final and crashed on approach just to the north of the runway.
