I fly for fun
I fly just for fun. I have clocked up 500hours over 8 eight years. Its been a hoot. There is a lot of satisfaction as you build your flying skills and once you have a licence flying is a great way to see Australia.
It's not cheap and therefore you need a good job or, better yet, a rich wife. RA is cheaper than GA but with GA it's possible to take friends and family with you. If it is just you and one other maybe RA is all that you need.
If you have the spare cash why not fly?
