I don't want to get into the great debate of this whole thread. But just for a fact. In the pipelines before any land is cleared fauna handlers must be present to remove all wildlife in the area been cleared and move them to safer areas. It's was common to come back to the part of the line we were working on the next morning to find the trench dug the previous day has a kangaroo or snake in there. The handlers would be there within the hour to remove the animal before any further work was commenced.
