Hadn't heard about the Cougar S-61, but here's a link to an article from Flightglobal.com about the Carson Helicopters Sikorsky S-61N Shortsky / 'Fire King' which is already here in Perth for firefighting trials. It has already seen some action, including fighting a bushfire not far from where I live.
