butcherboy, conditions that make it dangerous to create any source of ignition were around long before angle grinders became readily available in the last couple of decades or so.
The act of using an angle grinder on a day of total fine ban is as deliberate act as that of someone flicking a cigarette butt out of their car window, an act that has also caused many devastating fires in the past.
One can only imagine how many more devastating fires would have occurred in the 1800's if angle grinders were available then, that century being a period of more frequent drought conditions than the generally wetter conditions that have prevailed across Australia since the 1940's.
