Looking here: http://www.openstreetmap.org/?lat=-16.917127&lon=145.771595&zoom=18&layers=B000FTF You will find an intersection with no restriction relations yet it routes and renders correctly. You can not go straight across on Minnie Street but you can turn left from either Minnie St to Lake St or viceversa and turn right from Lake St into either side of Minnie St. The section of Minnie St between the two sides of Lake St is not marked as oneway so becomes a two way section, which it is on the ground, as is the rest of the intersection. Generally if you map it as it is on the ground, by using oneway=yes where required, it will work out like this. Go to edit to see how the ways are tagged. If there was no u-turn permitted then you would have to use a relation to indicate that.
