But the secret to unlocking Wallabies young gun Noah Lolesio's seemingly limitless potential? Simply being the best version of himself he can be.

That's the advice given to the ACT Brumbies flyhalf as he eyes a Test debut in the Bledisloe Cup opener against the New Zealand All Blacks on October 11.

New Wallabies coach Dave Rennie and his right-hand man Scott Wisemantel are adamant if you're good enough, you're old enough - and to date the 20-year-old has shown he is just that.

Lolesio enjoyed a breakout Super Rugby campaign in Canberra and claimed man of the match honours in the Australian grand final as the Brumbies snapped a championship-drought.

MORE RUGBY UNION

Now the rising star has set his sights on helping the Wallabies to their first Bledisloe Cup triumph since 2002, when Auckland-born Lolesio was two years old.

"Wisey and Dave have been awesome to me, they've just said 'just be yourself, be the best version you can be'," Lolesio said.

"That's what has got me here so I'm going to try to keep doing that, not try to overplay my hand too much. I'm really looking forward to it, I get to test myself against the best players in the world. It should be good.

"If they choose me to start then I'll happily take that role. What the team wants and what I need can be something different so I'm just ready to do my best part for the team."

Lolesio at his best boasts vision some other players can only dream of. He sees space well ahead of others, can accelerate off the mark and he is far from afraid of heavy contact.

He is one of the brightest young talents in Australia, and perhaps world rugby. When he looks back at the Wallabies who have gone before him, it's Cooper that stands out.

"The razzle dazzle he had, he'd pull something out of his pocket and create something out of nothing, it was really exciting to watch," Lolesio said.

Now Lolesio, the cousin of former All Blacks speedster Francis Saili, finds himself as one of two emerging stars in the Wallabies' flyhalf stocks alongside NSW Waratahs sharpshooter Will Harrison.

The uncapped duo are jostling with O'Connor and Matt To'omua, veterans of 52 Tests apiece, for places in Rennie's match day squad during a busy international schedule.

The race to the No. 9 jersey is much the same, with Queensland young gun Tate McDermott hunting a start with Brumbies veteran Nic White in the box seat.

The pair locked horns during the Super Rugby AU decider just days before they went into camp, much like Lolesio did with his Reds counterpart O'Connor - the man he would room with when the Wallabies squad linked up.

"It was a bit awkward for me, especially at the start of camp, because we had obviously just beaten the Reds in Super AU and went straight into the same room as Rabs," Lolesio said.

"He's been awesome to me, honestly. He could have easily just turned the cold shoulder and brushed me, but he has given me some really wise advice.

"We hardly ever talked about footy in our rooms, we just talked about life in general, and his life lessons. Rabs has been unreal.

"[To'omua] has definitely helped me out, I think all of us 10s are having really good conversations off the field, just to get some clarity and knowledge around all the content we have to learn.

"Pup and Rabs have definitely taken the lead there, and they always ask for me and Harro's opinion. They're doing an unreal job and it's just humbling to be a part of this environment.

"We definitely ask for what they reckon first, because they've been there, done that, both of them have 50-plus caps.

"It's pretty cool how me and Harro are in here right now. We started from school, and then 20s last year, and now we're in camp. They've definitely got wise advice, Pup and Rabs, and we just try to pick their brains here and there."

Every trick of the trade they pass on makes Lolesio a more complete footballer in his own right. While he boasts glimpses of O'Connor, To'omua and even Cooper, that's all Wallabies coaches want him to be - just Noah.
