Broncos fullback Jordan Kahu is slowly finding his feet in his new role for Brisbane.

Quietly confident Kahu slowly looking at home

Jordan Kahu looked a completely different player to the one on show just eight days prior, following his starring performance in Brisbane's 10-2 win over the Sharks on Friday night.

With Darius Boyd set to miss a fair chunk of the year due to an Achilles injury, Kahu was handed the No.1 jersey for the first time in his NRL career last week against the Rabbitohs. 

In what wasn't the most inspiring beginning to the season for the utility back, Kahu's couple of mistakes against the might of the reigning premiers inspired him to bounce back in a big way against Cronulla.

Making it his mission not to make any crucial errors, a quietly spoken albeit very certain Kahu even earned the praise of his coach Wayne Bennett, another boost to the 24-year-old's confidence as he looks to make up for lost time in the NRL.

"The biggest person I let down last week was me so I just wanted to walk off the field against Cronulla knowing I did my bit and I think I did that," Kahu told NRL.com.

"I dropped balls at crucial moments [against Souths] so I made it a goal within myself against the Sharks not to drop the ball like that again and I guess that was a huge difference."

In what has been a very stop-start beginning to his NRL career – with multiple injuries playing their part – Kahu is just happy to be back playing.

Fearing he may jinx himself, Kahu wasn't prepared to talk about his previous woes which include three serious knee injuries, though he had no hesitation in discussing the daunting task of playing in a position he hasn't taken up since high school.

"All the nerves that I used to get when I was playing 20s have all gone so I'm feeling like a comfortable first-grader now and hopefully I can stay there for a long time," Kahu said.

"[Fullback] isn't an uncomfortable position for me either. It is just a matter of getting used to the habits and the things that I used to do again."

Another cause for excitement from Broncos fans was Kahu's tackling prowess behind the defensive line, in particular his fantastic, bone-rattling hit on Jayson Bukuya, who looked certain to score and make of a game of it for Cronulla in the final 10 minutes at Remondis Stadium.

Remaining steadily level-headed and unperturbed by compliments of his tackle on Bukuya, Kahu saw it as another requisite in his role as a first grader,

"I'm going to have to make those tackles every now and then," he said. 

"I'm the second line of defence so once they break that line I have to be there. It's just a job I have to do and hopefully I can keep doing it."

The Broncos will host the Cowboys in Round 3 of the Telstra Premiership.
