NSW coach Laurie Daley has scoffed at suggestions Australia's recent Test loss to New Zealand signalled the demise of Queensland's ageing stars, saying the Maroons' 30-plus brigade are far from a spent force.

Queensland have remained loyal to the bulk of the side that delivered a record eight straight series wins with several stars, including champion quartet Cameron Smith, Jonathan Thurston, Cooper Cronk and Billy Slater, over the age of 30.

Veteran forwards Sam Thaiday, Nate Myles and Matt Scott will all turn 30 before the series is out while 32-year-old centre Justin Hodges has stated that the 2015 series will be his last for Queensland.

All but Slater and Hodges were part of the Australian Test team that was overwhelmed 26-12 by the a much younger New Zealand in Brisbane earlier this month.

Slater missed the Test with the shoulder injury that has hampered his 2015 season while Hodges was denied a farewell Test appearance by coach Tim Sheens who opted for the younger Will Chambers at right centre.

The Kiwis' third straight win over Australia - the first time in 62 years they have won three consecutive matches - prompted calls for new blood in the Kangaroos Test side.

But Daley said people have read too much into the Kangaroos' run of losses.

"I think everyone's been quick to write Queensland off given Australia got beaten in the Test match," Daley said.

"If you look at the Australian team the last three times they've played the Kiwis, I don't think it's been at full strength.

"There's been key players missing, so I'd still back Australia if we were at full strength.

"I think Queensland have shown, and in particular the guys that are on the other side of 30, that they're champions.

"You kick a champion when they're down - they'll always come back and bite you.

"I don't think the media have done us any favours in talking about the age of the Queensland side.

"I can guarantee the coach of the NSW team and players in the NSW team respect them a great deal and we know that they're going to be ready on Wednesday night."

He'll forever hold a place in State of Origin folklore as the man who broke the Blues drought but Daley insists his side's 2014 series victory has taken no shine off Queensland's aura.

"Queensland are just a fantastic team, probably the greatest in their history," Daley said.

"I think we all fear Queensland every time a State of Origin game is played regardless of who's in [the team] because they've pulled off some of the most remarkable victories in Origin history when no one's given them a chance.

"They've been a great team for the last decade, so it's going to be a big ask for us.

"I can't fault our prep, the guys have really bought into what we want to do and trained really well.

"I think we've all been around long enough to know that the other team trains really well as well and it just comes down to what happens on the night."
