You can't really get proper blanks, but you can get EPS foam from Foamex. They have
offices in both Melbourne and Sydney. Not sure about the other states.
+1 - there's one other place in Sydney that sells foam blocks I've got it at home. Depending on size and location you could try the guys a Shapers in Qld, I think they get their standard EPS in larger blocks or some one that makes prone paddle boards as there EPS (Bennett, deep) they might be able to help you.
