I'm not sure about that one the routing will already let you turn there like this https://www.openstreetmap.org/directions?engine=graphhopper_car&route=-27.558516%2C152.278678%3B-27.558694%2C152.278799

usually we wouldn't model the intersection like that unless there is a large traffic island in the middle of the intersection.
