Hi Kelly and welcome to the forum,
I'm not sure we have any actual verified dropship suppliers for those products bases in Australia, however it's well worth checking through the directory to see if you do find someone you would like to contact and discuss doing business with. In regards to the supplier link in your post, it's a directory, same sort of thing as we have here for our members, however I have no idea if they actively verify suppliers to ensure they are safe to deal with before adding them to their directory or if they just add them with no knowledge of them at all.
I would suggest contacting them and find out what sort of verification process they put them through.
