There are schools and businesses where the study of philosophy is not something to roll one's eyes at, here in the united states. I'd imagine the same to be true of australia or Japan/many asian countries. Having attended one such school here, though not for philosophy, I found a decent amount of students and professors willing to engage on all manner of subjects, and a core curriculum that required all students to take some philosophy, art and similar courses. Of course this is a bit unusual, a weird school, for sure.
My first 'real' boss when I went into programming was smart and funny; his first degree was in philosophy.

Folks here have also suggested not one course of study for the profoundly gifted, but two or more courses of study being the best way to really challenge oneself. Best of luck to you!
