IT'S not hard to see how passionate Apisai Koroisau is about rugby league.
For him, uprooting cassava during the Vodafone Fiji Bati team bonding session at the Serua Island is tougher than jumping onto a field of bone-crushing tackles and knocks.
Riding on his passion for the sport, the 20-year-old hopes to sail through the storm that he is set to face during the Rugby League World Cup which starts at the end of this month.
Nippy dummy half Koroisau is unfazed and like a true warrior, he is ready to take the challenge head on.
"Probably how to catch a boat to get to the main island and uprooting cassava, that was hard," he said of the experience on Serua Island.
The day-long session with fellow national players has made Koroisau more determined about Fiji's chances at the RLWC, which will be held in England and Wales.
"It's a massive honour to be part of the team which has a high-calibre players," the South Sydney Rabbitohs player said.
"People are expecting us to go far this time around with the calibre of players we have and hopefully we can provide that."
Koroisau, who hails from Nadi, had set his sights on donning the national jumper at an early age.
In 2011, he took part in the Battle of the Bati to make the national team for the Test matches against the PNG Kumuls.
Koroisau fell short of selection that year but it didn't deter him from giving another shot at his dream.
"I was a bit young the last time and this year (coach) Rick Stone picked me and is pretty keen to use me, I guess," he said.
"I think discipline is the massive thing for us. It's always been important and something the Fijian players didn't really have because of the brand of footy we play, which is throwing the ball around but I think holding the ball, running hard, tackling hard will get the job done for us.
"We can get further in this world cup, they did really well last time but I'm definitely keen to see how it goes in 2013."
With this ruthless attitude, there is no stopping Koroisau when the Fiji Bati starts its RLWC campaign against Ireland on October 28 in Rochdale.
