Instead he will embark on a new journey in the United States after receiving a scholarship to attend San Diego State University.
He is chasing "the American dream" and an economics degree, and the waterskiing scholarship has opened up new doors for the Northland slalom skiing recordholder.
Leaving behind his rural Puhipuhi Rd residence and his family's training lake, Williams admits "it's something different [but I] had to move out eventually I suppose".
"I won't come back and do a lot of skiing but will hopefully get back [home] a bit."
Departing for the United States this weekend, Williams will base himself in Florida for two-and-a-half weeks before heading to Spain.
While he's looking forward to escaping the chilly training conditions that New Zealand's winter coughs up, the warmer conditions overseas will present several obstacles of their own.
"It's probably just around 30C but it's 100 per cent humidity so it's really hot," Williams said.
"One of the big problems is your hands rip up [so] when I go over there I'll duct tape my hands up because the warm water tears them apart."
During the past year Williams has been training hard in anticipation of the world champs and his big move abroad.
However, he and his many supporters will have to jump clear of one more obstacle before he departs this Sunday.
Williams will run out on the rugby pitch for Mid Northern's reserve team tomorrow as they take on Old Boys Marist - something he's been doing throughout the 2015 season despite the threat of injury.
"I'll have my fingers crossed for that one," his father Glen said.
