Hi, i come from Macau. In terms of the aviation industry, if you can speak English language and get hold of a couple of relevant licenses then you will have a pretty good chance of getting a job and earn roughly MOP 20000. For pilots, i think F/O roughly 45000+ and captain 75000+ (Air Macau, A320 family and A300) (MOP is the Macau currency, also called Patacas.)
In terms of the living, renting a normal sized flat will cost you MOP 4000 a month. Food is cheap, plenty of restaurants, also supermarkets. Most western people find the Taipa area (where the airport is) is easier to live in rather than the main Macau peninsula. I mean food will cost you no more than MOP3000 if you eat at normal rest. or cook yourself. The taipa area is relatively quiet but it may be still a bit noisy compare to western countries (Since Macau is one of the most dense area in terms of population.) Living is okey, a lot of entertainment, casino, night clubs, good pubs and places to drink and chat with friends in the new breed of huge hotels. Local people are nice, although many of them can't speak English but generally nice. Transport, not so good....bus service....4 out of 10 i would say. Getting a car is almost a must if you wanna get around quickly. However, taxi service is cheap, MOP 11 to start and roughly MOP1 for each extra kilometer. Bus from 2.5 to 5. Hope it helps mate, good luck to you! come back if you have more questions!
