Wallabies' Fijian flavour at its most sumptuous yet

Inspired by the hot-stepping, tackle-shredding highlight reel that was Rupeni Caucaunibuca at the 2003 Rugby World Cup, Marika Koroibete looms as a key strike weapon when the Wallabies open their 2019 campaign against Fiji in 12 days' time.

Koroibete has seemingly gone to another level this season with his confidence and skill-set at an all-time high following his switch from rugby league at the end of 2016.

The Wallabies winger was in devastating form against Samoa on Saturday night, finishing with man-of-the-match honours following a brilliant attacking display that yielded 136 metres, three clean breaks, seven tackle busts and a blistering try that turned four Samoan defenders inside out.

He also threw the final pass for Lukhan Salakai-Loto's try, a moment that reflected just how hard he has worked after seeking the counsel of Will Genia and Quade Cooper at the Rebels during the Super Rugby season.

"I just had a look at my game and figured out what I needed to work on and what I've been doing well, just keep doing it," Koroibete said of his form. "Switching to rugby, sometimes I was going around for the sake of it and now [I'm trying] to be more effective.

"It's started at the Rebels this year, I spoke to Quade Cooper and Willy Genia, they helped me a lot of that and they gave me some tips which I tried to bring on later with Super Rugby. I know it works and then coming to the Wallabies; the style of game we've played this year it's blending so well and I just go in there and look for an opportunity and try and get as [many] touches as I can."

Koroibete's sensational form suggests the Wallabies' Fijian influence is arguably more potent than it has ever been at Test level, with Samu Kerevi enjoying his best Test season yet and Isi Naisarani making a solid start to his international career after serving a residency period earlier this year.

After taking some time to find his feet at the start of the year, Koroibete has certainly repaid the faith of Cheika, the man who helped bring him across from Melbourne Storm.

"There's no need to put a lid on it, is there? He keeps learning more about the game as he goes on," Cheika said of Koroibete's potential. "He's got so much energy and he's a real favourite inside of the team; he's got a calm demeanour but he's a bit of a joker as well and there's always something going on around him.

"The first half of the year, I'm not sure what was going on. But the back half of the year he's really come on. So we'll be looking to try and improve him and I think he'll really enjoy this World Cup; he likes the big occasions and there's no bigger occasion than Round 1 in the World Cup."

Australian rugby fans will remember as well as anyone the brilliant Caucaunibuca destroying opposition defences during the 2003 World Cup Down Under. The Fijian winger made his mark on World Cup history with a series of blistering performances, particularly against Scotland, and inspired a generation of young Fijians, including Koroibete, in the process.

"Definitely Caucaunibuca, he's a village boy, grew up in Fiji and I always looked up to him," Koroibete replied when asked if there were any wingers who'd inspired him during a World Cup.

"He's one of the great finishers; his speed and agility, and ability to step at full speed was just unreal. And he was so quick as well ... the Scotland [try] was one of my favourites, in the corner."

Koroibete's sensational form has set up a mouth-watering battle with John McKee's Fiji in Sapporo on Saturday week, the Islanders boasting a bevy of powerful ball-runners themselves, including Koroibete's fellow NRL convert Semi Radradra.

"Semi's an exceptional player," Fiji coach John McKee told ESPN. "He made the transition from league back to union pretty seamlessly; he's been in great form in Europe.

"Although he's been a little bit quiet for us across the PNC [Pacific Nations Cup], we're expecting good things in Rugby World Cup."

McKee said Radradra's stint in the NRL had made him more of a professional.

"His background was in rugby union; he played sevens for Fiji before he joined the NRL, so he understands the game of XVs really well. I think, out of rugby league, maybe it helped his training ethic; he's certainly a very dedicated trainer and really knows how to look after himself and get the best out of his athleticism."

Radradra will likely come head-to-head with Kerevi in the midfield while Koroibete will surely also get the chance to test his newfound roaming licence on Saturday week, not that his pick-and-drives have necessarily pleased everyone.

"I've been stealing some of their [Wallabies forwards] tries and they tell me to go back to the wing."

It won't matter whether Koroibete's tries come from one metre or 100 starting next Saturday, they'll all be of equal value to a Wallabies side still to find its attacking best.

And they're likely to be cheered just as loudly back in his Fijian village of Naraiyawa as they will be across Australia, more-so those that follow the Fiji opener against Wales, Uruguay, Georgia and beyond.
