If I change the sentence to "Each Australia and Canada ~" from "Australia and Canada each ~", does the meaning change?

It would not be grammatically correct to place "each" in front of the subjects here, because "each" is singular, so it cannot go in front of these two countries which are plural together. However, if you instead said "both Australia and Canada..." this would be correct because "both" is plural. If you put "both" in front of Australia and Canada, this would not change the meaning of the sentence.
