Awfully far is a bit of an overstatement based on SA2's map alone.

The games can sometimes be inconsistent with the location of South Island; In Chronicles, Central City was located on South Island.

Either way South Island isn't isolated from civilisation, that's something that'a pretty much consistent throughout it's appearances.
