You'll be fine, I left one in the drone and the other in a lipo bag. The only interest I ever had were enquiries as to where to get one. I had a printed copy of the the dji spec sheet in case I was ever asked, that has never happened.
Nope, the controller is the least of the threats, turn it off and pack it in the bag.
For a drone similar to a Phantom, they are classified as a hobby and it's basically a free for all with the obvious exceptions. I flew mine in the middle of metro Manila and gave the controls to a cop for a try. You wouldn't be doing that in Perth... For drones that you are deriving an income from, the beaurocracy is unbelievable and an expensive process, by Philippines standards, and mostly avoided if you can. As for Cebu and even Mindinao, if you avoid the congested areas, go for it. The locals are extremely curious and love watching them fly.
