China Southern flight 344 from Melbourne to Guangzhou developed a flap system fault shortly after takeoff from RWY16, following discussion with ATC the aircraft was directed to position TEMPL (SW of Melbourne) to hold at 6000ft. After around 45-60 minutes in the hold and with no remedy in sight the crew advised ATC that they wished to return to Melbourne but would first like to burn some more fuel to reduce weight. An overweight uneventful landing was later made on RWY16 with the aircraft rolling through to the last taxiway (Kilo).
