This could be the smallest roundabout in Melbourne. The extruded circular centre-piece is only about 1m in diameter, yet there are two generous traffic lanes which pass around it. I think the unusual configuration is influenced by the requirement for buses to easily move around this area. This picture was taken in Deer Park. Related post: Round car-park. Related fact: roundabouts are also known as “traffic circles” in countries other than Australia.
