I was able to sign it using my Australian home address. Just pick the non USA resident option. With the zipcode/postcode part I changed my 4 digit postcode to 5 by adding a zero to the front of it (it wouldn't accept 4 digits) . Then it provided me with a link to share on my Facebook newsfeed to encourage others to sign. Hope that helps.
