Flying certainly is a fun way to pass your time, and definitely worth the time, effort and expense. And you can get your Recreational Pilot Certificate (RPC) at 16. You will need to get your pocket money ready though, flight training to certificate issue completion normally costs about $8000 to $10000, but you only have to pay out at 1 lesson at a time, usually from $200 to $250 per 1 hour lesson. Alternatively you may qualify for a scholarship through RAAus, it may be worth checking it out, you are at the right age for it. Scholarships - RAAus
I know another young man around your age who got his RPC at your age through the RAAus scholarship. He trained at the same flying school that I went through. Last time I spoke to him, he was looking to join the RAAF as a pilot. They were indicating to him that they acknowledge the high quality training that RAAus deliver, so it will be a good foundation for further training.
I regret not becoming a pilot at your age. I left it until I turned 50, but better late than never.....
