A quick look...I don't see anything about long lines, but 'drift lines' are not allowed. A long line is a type of drift line. So, probably illegal in Australia.
I agree Mark.
It is not a fun way to fish. Also by catch is an issue which includes turtles, birds, mammals and sharks.
It is not for me, but if it is legal and you want to try it, go for it.
