As well as the low level training, you will require a Mustering Rating. usually a 10 hour course in how to stay alive while carrying out a pretty mundane sort of job. the novelty of low flying will wear off after about 20 hours, then its all about getting the job done and keeping the customer happy. the biggest part of staying alive in this game is the same as most other parts of the flying game. be careful, learn the limits of your aircraft, learn your own limits, don't take unnecessary risks (like buzzing station hands, jillaroos, ect.......they only think its funny once, then they think your a dangerous dickwit).
I personally don't think its a time building job, I think its a job to take very seriousely as a full time type of job, like ag flying.
but hey, its only my opinion. lots of others have done it to build time and gotten away with it.
Hey RV, say G'day to Arnold for me.
