NOTHING but Blue skies.

After years of Queensland rule at representative level, the most promising generation of New South Wales juniors in years has the potential to dominate Australian Test sides of the future.

Kangaroos coach Tim Sheens is well aware of the Dad’s Army tag that has accompanied his side in recent years.

With the likes of skipper Cam Smith, Paul Gallen, Johnathan Thurston and Cooper Cronk headlining a list of up to 10 Aussie regulars on the wrong side of 30, the veteran mentor has admitted a changing of the guard is due sooner rather than later.

BROOM SET TO SWEEP THROUGH TEST SIDE

“The Australian side is of an age where there will be some change coming,” Sheens told foxsports.com.au on Monday.

“We’re not going to push them out before they are ready. It is coming and we’ve got to address the fact that the younger ones are the ones we need to be starting to look at.”

So with an eye to the future and an age limit of 25, we take a look at some of the names set to feature in the Test side, and pick a composite team to take to the 2018 World Cup.

Fair warning to those north of the border, this is one rep side with a touch of the Blues.

Backs

With an unprecedented number of Kangaroos stars ruled out of last year’s Four Nations, Sheens took the opportunity to blood the likes of Souths duo Dylan Walker and Alex Johnston (though Johnston didn’t see any game time) and the Kangaroos’ youngest ever debutant in Knights whiz kid Sione Mata’utia.

Penrith’s Matt Moylan was also named in last year’s squad without getting a run, though he currently occupies the box seat for a crack at the NSW No.1 jumper vacated by Jarryd Hayne. Teammate Josh Mansour also featured for the Roos last year, rounding out a Blues back five with potential and speed to burn.

Throw Tigers fullback James Tedesco, Roosters flyer Daniel Tupou and Parramatta’s Will Hopoate (who despite playing Origin in 2011 is still just 22) into the mix and there’s reasonable scope for a Bluewash of the green and gold backline.

For the Maroons, Dane Gagai (24), Tautau Moga (21) and gun rookies John Folau, Cameron Munster (both 20) and Valentine Holmes (19) are all set to feature at some point in the Queensland backline in coming years, though with the exception of Gagai, none have yet built the same NRL or top level experience as their New South Wales counterparts.

Halves

For years it’s been nothing but banana benders in the Australian six and seven jumpers as Darren Lockyer, Johnathan Thurston, Cooper Cronk and Daly Cherry-Evans have dominated.

While Cherry-Evans, Ben Hunt and Blues counterparts Mitch Pearce and Adam Reynolds will be around for a while yet, the generation behind them is where New South Wales holds a distinct edge.

Tigers duo Luke Brooks and Mitch Moses have ‘made for rep footy’ stamped all over them, while Sharks sensation Jack Bird is certainly on Sheens’ radar judging from these comments.

“Young (Jack) Bird has come through this year. I haven’t seen a lot of him (but) I gave him his first (Cronulla) jumper,” Sheens said.

“I was asked to give Chris Heighington his 250th and gave Jack Bird his first. I’d love to give him his first Test jumper.”

Also waiting in the New South Wales wings are Canberra’s Mitch Cornish (22) and Roosters tyro Jackson Hastings (19).

Anthony Milford is Queensland’s trump card, regardless of whether he forges his career at the back or in the halves, while the demand for Titans rookie Kane Elgey only grows as he looks more assured with each NRL outing. Canterbury’s Moses Mbye (21) has also impressed despite being shuffled around the Bulldogs backline as the blue and white’s Mr Fix It.

Forwards

Throughout the Maroons eight-year Origin dominance their front-row stocks have seemed at times limitless — Matt Scott and Nate Myles simply rolling off the production line to replace Steve Price and Petero Civoniceva.

In Aaron Woods — still only 24 years old but playing well beyond his years — the Blues have a ready-made metre-eater ready to go when Paul Gallen hangs up the boots, while the potential for a decade long running battle between Blues firebrand David Klemmer and the Maroons Dylan Napa is mouth-watering.

Tigers big boppa Matt Lodge (19) is another with more than enough fire and brimstone for the game’s fiercest arena for the cockroaches, while Canterbury’s Lloyd Perrett and Brisbane’s Joe Ofahengaue both have huge raps on them north of the border.

As always the Blues back-row stocks run deep, 22-year-old Boyd Cordner has already been earmarked as a future skipper while Josh Jackson, Ryan James and Dale Finucane all have rep experience under their belt already.

Among the dummy halves James Segeyaro (24) gets the nod, but he and Jake Friend (25) are likely to be locked in a lengthy battle for Cam Smith’s No. 9 jumper, while New South Wales have Michael Lichaa (21) to call upon.
