Hailed as the fastest player in rugby league, Walker is yet to make his NRL debut but the 19-year-old fullback has scored five tries in as many matches this year for the Titans in the national youth competition.
"Shannon is an incredible prospect and is on his way towards representing the club at NRL level in the near future," said Titans managing director Michael Searle.
"His speed, agility and explosiveness needs to be seen to be believed.
"Our head coach John Cartwright has been patient regarding Shannon's elevation into the NRL, which gives him the knowledge the club has a long term view on him."
Walker, a Junior Kangaroo, said he was pleased to settle his future on the Gold Coast just two hours drive from his family in Kyogle, in northern NSW.
"It's pretty exciting," said Walker, who clocked 10.76 seconds for the 100m at age 16.
"I didn't really want to move away from the Gold Coast.
"My fiancee Casie and I are really happy here."
Walker, a regular member of the Titans fulltime training squad, said he was focused on developing his trade to achieve his goal of making his NRL debut.
"I'm not in any rush," he added.
