The signature of rising Australian sprint star and internet sensation James Gallaugher is proving even harder to catch than the young man himself.

Video of Gallaugher sprinting to an amazing win in a relay race at the NSW School Championships went viral on the internet and he has since been pursued by several sport clubs and sponsors.

Gallaugher spoke exclusively to Nine News about being dubbed "The next Usain Bolt".

"I'm 12, I go to public school and I'm really fast," Gallaugher said.

Born in Darwin but now residing in Ulladulla on the NSW South Coast, Gallaugher runs 100m in 11.72 seconds.

"That's an incredible time for him and what they need to do is really nurture him - he's obviously a talent," former Olympic sprinter Melinda Gainsford-Taylor said.

"We also have to be careful of rugby league obviously - they'll be knocking at the door."

Five NRL clubs have shown interest in signing Gallaugher, who already plays for NSW juniors.
