Nizwa, over 60 it's unlikely you would crack the Aus or NZ scene. Though not impossible if you have the right type ratings. But PNG welcomes pilots over 60, particularly those with good rotary or Twin Otter time.
PM me with details of your experience and I may be able to suggest a couple of likely prospects in that part of the world.
As for JTV's wind-up, my cohort have 30 years on you and I reckon any of us could still teach the average 38 year old a few tricks - and not just flying tricks either....... In fact, ageist comments from mere beginners (yes, if you are only 38 I am talking to YOU) actually inspire us grumpy old men to hog the seat for another few years just to p!ss you off.
