You'll have to be specific, all five of the roads that enter this roundabout are different, none actually continue through it. I think the maximum speed limit in the area is 60km/h though.
Edit: Also, the weird looking building in the first picture? That's the Royal Melbourne Hospital. There is A Lot going on at this roundabout. Though I guess as far as it not being "bad" it is probably the best intersection they could have built for this location. The cycle length if it were a signalised intersection would be insane.
