Wallabies goal kicker Christian Leali'ifano is confident he will be able to ignore laser lights if they are directed his way when Australia play Argentina in Rosario this weekend.

Leali'ifano has no experience of the controversial practice, now associated almost exclusively with Argentina home crowds, that prompted the referee to give All Blacks five-eight Aaron Cruden a second crack at converting Julian Savea's opening try in La Plata last week.

But the Brumbies' sharp shooter says he has enough faith in his kicking process to block out any beams shone from the stands at Stadio Gigante de Arroyito.

"I saw a bit of the [Wallabies] game last year and [the All Blacks game] last week, I saw Aaron Cruden trying to kick there, but I don't really worry about it too much," Leali'ifano said.

"I guess you have to try and block it out visually. I have a certain target on the ball that I look at and concentrate on the most, because that's my target area and striking zone.

"If the laser is around that area it might distract me but if I stay focused on that hopefully nothing else goes wrong."

The 23-year-old made his Test debut this year but is emerging as one of the coolest heads in the game, kicking 27 from 32 for the Wallabies with a success rate of 84.37 per cent.

Where Welsh kicking prodigy Leigh Halfpenny brings coach Neil Jenkins on to the pitch behind him while he kicks, Leali'ifano prefers coaches take a hands-off approach.

He communicates with kicking coach Damien Hill most often via text message due to Hill's frequent travel and can manage just two dedicated sessions a week owing to a small fracture in his right ankle, which could require surgery at the end of the year.

Leali'ifano said he liked it that way, preferring not to over-think - or over-talk - his process or the possible effects of laser beams on the ball.

In-game he also keeps it simple, ruling out the Halfpenny-Jenkins approach in favour of something more lighthearted.

"[Strength and conditioning coach Scott Murphy] Murph usually brings out the tee and we talk about other things, whether he's seen a good looking girl in the crowd or 'where's the water' or what the coaches are saying," he said. "He doesn't like saying too much when he brings it out, we just like to have a little giggle."

Despite the fortress-like grounds and passionate crowds in South Africa, Argentina has emerged as one of the most hostile countries to play in, at least on the pitch.

Kurtley Beale and Mike Harris were subjected to the laser treatment during the Wallabies' 25-19 Test win here last year.

And a Test in Buenos Aires in 2002 was labelled the "dirtiest ever" by the Wallabies' then-vice captain and No.8 Toutai Kefu. Replacement hooker Adam Freier and flanker Matt Cockbain were eye gouged, while players reported being spat on by the crowd as they entered and left the field.

Leali'ifano is proving adept at shutting out almost anything, including any understanding of what might hinge on a kick. He counts his match-winning goal in the second British and Irish Lions Test in June as his most significant, but only in retrospect. He had little idea at the time about what hinged on him nailing it.

"The more we talk about it or the more I think about it, the more its gets to me a little bit," he said of the pressure.

"I am sure kicking again here is going to be tough but I am hopefully kicking more conversions than penalties."

Only wind seems to upset Leali'ifano's radar, but even there he is working through it. He and Hill talked after the Wallabies difficult win against the Pumas in Perth last month and decided Leali'ifano would aim straight no matter what the wind was doing.

"I've seen a YouTube clip of Dan Carter kicking one and it bends back in with the wind but that's Dan Carter I guess, that's pretty freakish," he said.

"I did that once in Perth, I was aiming outside that right upright and it stayed there and I thought the wind would help it bring it back in.

"I'm just going to stay normal now."

The Wallabies trained in Rosario on Monday, with five-eighth Matt Toomua sitting out the session with a rolled ankle. He is expected to train on Thursday before a decision is made about his availability.

The Pumas are staying in Buenos Aires until Friday, leaving Australia with the run of the riverside city.
