Here is a flywheel from a 375 Sprint that I took off. It looks to be more substantial than the old one and doesn't have that big pair of holes near the edge that appear to have been the beginning of yours initial failure. $5 for my time and dropping it off in Bundaberg for you seems fair. PM me if you want it with address details. Will be in Bundie most of Monday morning on the 4th of April.
