There have to be good reasons why even the Newfies are buying some CL415s.
Might have something to do with the fact that freshwater covers 7.7% of the surface area of Labrador/Newfoundland. Not to mention a great deal of protected sea area on the coast.. That protection is important, as scooping is limited to conditions of less than (IIRC) 1 metres swell. How does that compare with South-Eastern Australia on a bad fire day in the middle of a drought??
They're a very productive aircraft when the conditions suit them. Eastern Canada is probably as good as it gets for that syle of aircraft. SE Australia offers us big problems when it comes to locating, large open (Think about the number of dead trees in our inland reservoirs) bodies of water during droughts. It's a whole different pot of Bouillabaisse.
