Carney failed to get the Blues' backline going, while two missed kicks at goal and a penalty he failed to put into touch when his side was reduced to 12 men - with Michael Jennings in the sin bin - proved very costly.
"He did a pretty good job tonight - but for us, I thought we did an even better job on him defensively," Queensland captain Cameron Smith said.
"We tried to minimise his impact on the game and I thought we did that.
"He's had a taste now and I think he'll be a lot better next time."
There's little doubt others too will improve, but the performance of prop James Tamou would have convinced Stuart he finally has someone to provide valuable help up the middle to ironman skipper Paul Gallen.
There are still some queries over Jamie Buhrer's worth to the team after he made little impact off the bench, while the likes of Anthony Watmough and Tom Learoyd-Lahrs will come into consideration for a recall on the bench.
"I thought James Tamou, for his first game of Origin football, was outstanding," Stuart said.
"I thought Jarryd [Hayne] was back to his exciting self. He looked dangerous every time he touched the footy.
"A number of the boys in the change room got a lot of credit from me tonight.
"It's game one, we've got to dust ourselves off - which we will - and go again."
And the Maroons will be ready for another torrid battle at ANZ Stadium on June 15, not that they underestimated their opponents in Melbourne.
In fact, Smith went to great lengths to give credit to the Blues.
"They're a great team and they play good football."
