Blues skipper Paul Gallen has fired a warning shot to his teammates; be complacent at your peril.

After leading the Blues to their first series win in nine years, Gallen said he is about to embark on the proudest moment of his rugby league career when he lifts the shield after the third game on Wednesday night.

But first, the NSW side have one last blow to deliver to the Maroons, as they eye their first series clean sweep since 2000.

''We know how hard it is to get hold of these jumpers,'' Gallen said. ''When you've got hold of it you don't want to let it go. If you don't perform to a certain standard you may not be here again. That's everyone's motivation.

''It's important for us to play well as a team. The Blues jumper deserves a great performance by every individual. If we do that, hopefully we can win.

''Our goal was to win the series. We've done that. Now everyone's goal is to grow bigger. We want to win this series three-nil. It's very important for us. We spoke about complacency at our first training session. We haven't spoken about it since. We have no excuses going into the game.

''We are well prepared and we want to win.''

Gallen will end years of torment when he finally gets his hands on the shield after the game on Wednesday night. Of the present Blues squad, it is a feeling only experienced by interchange back-rower Luke Lewis.

''I can't wait to hold it up,'' Gallen said. ''I couldn't care less if there are 55,000 or five people here. It's going to be a great moment not only for myself but for NSW. Not only for this team but for every player and coach that has been involved in the past eight years.

''We've played against this side who are blessed with so many great players. On top of that, they've been a great side. To finally beat them it's a real great moment for us in history. To hold that trophy up it'll be a great moment.''

Gallen has called on referees Gerard Sutton and Ben Cummins to open the game up by maintaining the 10 metres. Sutton will control his first Origin after Shayne Hayne was dropped following game two.

Hayne and Cummins had refereed the first two Origins.

''The 10 metres is the big one,'' Gallen said. ''I don't want to see them come in and stamp their authority and blow silly penalties for the sake of it.

''I thought the way the referees handled the first game was OK. The second game they let both teams get away with a lot.

''No one wants to see penalties blown; they just want to see people rip into each other like we have in both games.''

The Blues completed another flawless Origin campaign with a captain's run at Suncorp Stadium on Tuesday morning.
