this applies to Australia
An experienced agricultural pilot can expect to earn in the range of $A50-100,000 a year. Hard work, tough to get into but the rewards are there. It is also a fairly risky occupation. Obviously flying low level has it's own risks but the chemicals can take a terrible toll on the body. Cancer is a real risk.
Low timers can find it hard to get into.
Bush experience is useful, tail wheel time also.
