here is an part of the article from the MotoGP website where it states Casey was given the choice of any part of the circuit:
Stoner was given free rein by the Fox family and the Phillip Island management to choose what part of the circuit would have his imprint – and without hesitation he nominated Turn Three, a fast downhill left-hander which MotoGP riders hit at over 250km/h. And the turn’s a constant reminder of Stoner’s sublime talent as he ‘hangs’ the rear tyre out lap after lap.
"Turn three is probably my favourite one in the world. I am almost flat out in fifth gear through there and that is pretty damn fast and it really gets your blood flowing that’s for sure," said Stoner.
"It always gives me a great rush going through there so to have a corner named after me at Phillip Island is something quite special. It is a great privilege."
"The Island was designed 60 years ago before computers. It follows the flow of the countryside. It is a classic track and beyond anything else we race on. The high speed corners get your heart racing and there are a lot of corners you can slide through."
Stoner’s completed thousands of laps around the 4.4km Phillip Island circuit in testing and race weekends over the last decade, but one particular journey through turn three stands out for him: a no holds barred qualifying lap in 2011.
"With new tyres and load of grip I went into turn three and shut off for the least amount time I ever have and then got straight back on the throttle," said Stoner."
"The data on my Repsol Honda RC213V showed I was at 262km/h and the slowest point of the corner was 258km/h. It was bloody quick. I was completely sideways and I had my front wheel halfway across the kerb."
"I got it as good as I ever have, and that was my most memorable moment through there."
