Snyders, Lauren Boyle, and Matthew Stanley and expected to lead the charge over the next four days at the West Wave Aquatic Centre in Henderson.
Snyders, chasing a third Olympics in Rio, has returned from his base in Los Angeles where he trains under famed American coach Dave Salo in a star-studded programme.
The breaststroker, who turned 28 last week, attended his first world championships a decade ago. After a medal in the Pan Pacific Championships last year, Snyders is looking to again qualify in all three distances this week
“I see the worlds as a stepping stone towards Rio,” Snyders said.
“Obviously I want to do well at the world champs so all my focus for this year will be on that and making the final in the 50m and 100m breaststroke, which will set me up nicely for Rio next year.
“I am confident in myself and preparation. Since taper has started I am feeling good in the water. I just need to be patient – that is the hardest part of tapering.”
