The amount of time varies, from sending off phase one to being in newzealand didnt take me much longer than 7 weeks but others were in selection for almost a year, id like to think its because im amazing but sadly i dont think thats the case. Chasing them up pays off. Hassle them, i know they managed to loose a few peoples applications. One guy got a call six months later after he'd moved to america!
