The earth is the metal part. When wiring one up there is the screws for the earth. These plugs (male end) are made for bali and fit tight. The other ones are universal with smaller diameter pins and tend to fall out. Believe me I have made up a few cords for friends also. Get from Ace and lots of other places. I also attach a Bali Female end to the other end of an extension cord. Great for stuff you buy with two pins. No adapters needed for Aust.
I have a cord 30cm long from an old extension cord with Bali Male fitted. Then take a double adapter. The older style with the angle not flat then two large fitting plugs slot in. The flat ones don't go well with some larger chargers.
Never found the need to charge more than two items.
