Pad See Ew noodles are hard to find in Australian supermarkets like Coles or Woolworths. The largest noodles you'll be able to find there are the Pad Thai variety (which is actually what I used for my recipe).   If you're after a thicker noodle to make authentic Pad See Ew, I would recommend checking out Asian supermarkets or specific Thai supermarkets. They have specific noodles for this dish.
