Ospreydriver, ChildFlight Sydney were fundraising to get into a 609 at one stage. I remember seeing the ads. Maybe their plans were put on hold as the certification process dragged on, because I can't find anything about it now.
SEIFR, I imagine Canada and Australia have a lot in common regarding EMS needs; long distances, sparse population outside metro areas and a lack of airfields suitable for EMS aircraft in remote areas. It's a niche market though.
