Mate, you've gotta be winding people up, but if you are legit, I think you should let all your fellow students and instructors know that you bat for the other team, so that you can be accorded all due consideration and respect.
I'm not sure how comfortable all the other more normal students will be in the communal showers or other aspects that require them to be in close quarters with you, but be prepared for the occasional and not very pc comment.
Failing that, come dunnunder, I hear the Australian military these days gives everyone a fair go, they'd no doubt welcome you with open arms so to speak, so you could always consider having a crack at that. No pun intended.
Oh yeah - good luck
