The US Open champion will join 14-time Grand Slam winner Rafael Nadal and women's world No.1 Angelique Kerber at the year-opening tournament.
Wawrinka heads to Brisbane after beating Novak Djokovic for his third Grand Slam title in New York and reaching his highest-ever ranking behind the Serb and Briton Andy Murray.
"I'm excited to be heading to the Brisbane International for the first time in my career," Wawrinka said in a statement.
"I've heard such great things about the event and it feels like the right time to change up the start of my season."
