Ireland winger Keith Earls says Saturday's starting out-half Joey Carbery is as vocal in the 10 role as Johnny Sexton.  

The 22-year old Carbery, who recently signed for Munster for next season, has been selected at 10 for Saturday's first test against Australia in the Suncorp stadium in Brisbane. 

Regular out-half Sexton is renowned for his commanding presence on the pitch and is famously quick to bark instructions to the rest of the backline. 

Based on this week's training, Earls says that Carbery, presumed to be quieter, is not so different from the man he's replacing.

Speaking to RTÉ Sport's Michael Corcoran, Earls insisted that Carbery doesn't need any looking after.  

"Joey is the exact same. He probably doesn't get to do it as much at Leinster when he's playing full-back," noted the Limerick man.  

"At training this week, he's bossing (players) around. I've never heard him speak so much. Some fellas might think he's quiet but Joey will let you know if you're doing something wrong as well, which is great.

"I suppose he's getting a massive chance here in a massive game in a really tough place in the Suncorp.

"I have no doubt he'll be flying it. He'll probably have nerves and it's up to us as a backline to help him out. 

"Joey doesn't need looking after. Some of our young lads don't need looking after. It's all about looking after each other. It's about being a team and not going out as individuals."

Captain Peter O'Mahony also praised Carbery's attitude this week.

"It's been great. He's an incredible footballer," he said.

"He's really grown into that leadership role. I suppose over the past two years he's been getting better and better and he's a big character in the squad, which you need from your 10.

"I think he's growing all the time and it's a huge opportunity for him tomorrow."

Earls says he was happy to see Australia name a team filled with heavy hitters. He said that the Wallabies differed from the rest of the southern hemisphere in their approach to the breakdown. 

"It's a team full of freakish athletes," he said. "Folau, Kerevi, and Kurtley Beale. And then you have the experience of Foley and Genia pulling strings. And there's no need to talk about the back-row. 

"It's going to be a massive challenge for us. But we want all the big names against us and hopefully do ourselves justice and get a win. It'll make a win sweeter with all them athletes in it. 

"It's the difference between southern and northern hemisphere rugby. They like to throw the ball around. They've a lot of good individuals with unbelievable speed and footwork and fellas who love to offload. 

"But I think Australia are different because they've Pocock and Hooper at the breakdown. So, it's not like your typical southern hemisphere club team where they don't really throw many into the breakdown. The Aussie international team are strong all over the field and if we give them a sniff, they'll tear us apart."
