Big Deal! Meet The Richest 16-Year-Old In Australian Sport

Sam Walker is about to earn a whole lot more than you probably do.

The 16-year-old Queensland schoolboy rugby league star just signed a $300,000, two-year deal with the NRL's Sydney Rosters.

Yep, that's $150,000 a year for a raw talent who's not even eligible to play in the top grade until June 16th next year, when he turns 18.

"All my mates are obviously very proud of me," the Ipswich Grammar halfback joked when speaking exclusively to 10 News First reporter Bill Walker in Brisbane today.

No kidding. They're probably a bit jealous too.

Wanna play handball, Sam? Nah sorry fellas, gotta go join the NRL.

Walker is the son of Ben Walker -- an NRL star of the 1990s and 2000s, alongside his brothers Shane and Chris. All three played for the Brisbane Broncos (as well as other clubs).

Sam will head south in November to train with the Roosters over summer, and is being groomed to take over from Sydney halfback Cooper Cronk, a legend of the game who is retiring this year.

The young player showed admirable restraint -- and perhaps a bit of media training -- when he almost said "Cronk was the best halfback to play NRL", then corrected himself and said "in many eyes the best halfback ever to play NRL".

A subtle but important difference. Respectful, not opinionated. Well played, young fella.

"For Cronk to stay on and mentor me and improve my game would be a great honour, I'm really looking forward to it," the youngster added.

He also said he was looking forward to working alongside Roosters five-eighth Luke Keary, who he called "an unbelievable footballer".

But will Walker be ready for big time footy when he becomes eligible in the middle of next year?

"You never know, I guess. I just want to get down there and hopefully train the house down."
