Reffing was pretty average.. I preferred it when they let a bit extra go in origin. Jennings shouldn'y have been binned. Bird shouldn't have been pinged for that dump tackle either. I realise both incidents would have been red cards and about 4 year bans in rugby but origin usually lets the rules go a bit further.
I'm a QLD follower and I reckon NSW had it tough, that last try was pretty ridiculous.
