Queensland hooker Cameron Smith has warned NSW coach Craig Bellamy will fire his players with a siege mentality following the most traumatic preparation to an Origin game in 30 years.

Winger Timana Tahu's explosive walkout on the Blues last Friday has rocked the NSW camp along with the resignation of assistant coach Andrew Johns whose racial comment triggered Tahu's action.

Melbourne captain Smith knows Bellamy, his club coach, extremely well and expects him to use the setbacks to further galvanise his embattled team for Wednesday's second Origin match in Brisbane, which they must win to avoid a fifth straight series defeat.

"He'd try and use all these disruptions to pull them together and psyche them into thinking it's us verses the rest of the world," said Smith at the Maroons' Coolum camp on Monday.

"We're expecting a better side than we played in Sydney.

"If they don't win, then it's five series in a row and I'm guessing any player involved in that side, and the coach will not want to be remembered as the side that lost five in a row."

Smith said his Melbourne coach had learned the "siege mentality" well from his mentor Wayne Bennett during their days together at the Broncos.

"Wayne was probably the best in the business at that," said Smith.

"Whenever we'd play the Broncos and they'd had a big name player injured or something else would happen, Craig would always warn us they'd come out fired up and they usually did."

Returning after injury kept him out of the game one win, Smith admitted feeling empathy for Bellamy who has also had to deal with fall out from the Melbourne salary cap scandal this season.

"Even though I want to beat him on Wednesday night, I do feel for Craig," he said.

"He's quite a passionate bloke about his club and his state side.

"He's been put through the wringer this year with Melbourne and now with Origin.

"After game one he copped a hiding in the media down there calling for him to be sacked and now he's gone through hell this week.

"The Melbourne stuff has hit him pretty hard but he's a strong bloke and he's done really well to get through everything."

Queensland have spent the weekend in camp at Coolum on the Sunshine Coast and Smith said they'd done everything needed to win Wednesday night's game at Suncorp Stadium and secure another Origin series win.

The team have Monday off and will head to Brisbane on Tuesday for their final hit out at Suncorp Stadium without any worries after halfback Johnathan Thurston, under treatment for a calf injury, trained strongly on Sunday.
