I doubt anyone who was at Orimbah would want to steal your idea.
And don't take me wrong, I'm not paying you out, but it sounds like an idea that only the person who stumbled across it could pull off.
Note: Make sure you do it really really well, and justify everything in your reflection statement, as unless you do it runs the risk of being, quite honestly, laughed at by the markers (believe me, teachers wouldn't be very different from the guy on this forum who paid out your work. Hence, you have to do A LOT with that storyline so that it holds water, so to speak).
