Money, money, money!
To be more helpful to our Australian friend, the average pay in the Gulf for ATPL(H) 412/212-rated IR Captains starts at about US$335 and for Cojos US 185. Of course this depends entirely on which company you are looking at, whether you have the ratings or will need training, how much experience you have offshore - are you willing to work in Ira,. Sudan, Yemen, etc etc all of which usually sweeten the pot somewhat. Also the lower pay compnaies usually ofer good to fair accomodation. Very few offer 6:1 contracts. Mostly they want 6:6 or 8: 4 people. We all hope to see the pay improving with the New year as demand increases elsewhere for experienced hands, and whilst numbers thin very noticeably in some of the Arabian Gulf companies as pastures new get greener (as in dollars!). Good luck!
Hope this helps!
