There is actually no low level endorsement syllabus. Jobs done on so called "low level" endorsements include powerline inspection and survey work. Both of these jobs would be a lot safer if the pilot did an AG rating which doesn't just cover actual AGwork but flying in all sorts of situations with heavily loaded aircraft down low.
It's crazy a bare commercial can do 4 or 5 hours of so called "Low level endorsement" then load up a 182 with full fuel and 2 observers and go out in hot weather 10 feet above power lines. In these days of strict liability it will come back to bite CASA on the bum.
