Commentaries:
In verse 1, God indicates His audience: the "coastlands" and the "peoples from afar." Then, in verse 12, He tells more about the areas from where He will gather His people: "Surely these shall come from afar; Look! Those from the north and the west, and these from the land of Sinim [Vulgate: Australi]." Israel, God says, will come to dwell at "the ends of the earth," even in Australia.
