Heazlett's composed knock of 125 was the mainstay of the Queensland Academy of Sport's imposing total of 469, after the Queensland attack had decimated the home side on the opening day to dismiss them for just 77.
WA crumbled in the face of a Jack Wildermuth inspired attack, with the allrounder taking 5-8 from eight overs as the locals tumbled from 1-33 to all out for 77.
Wildermuth was capably backed by fellow Bulls players Mark Steketee (2-39) and Xavier Bartlett (2-14) while Cameron Gannon was frugal on the way to 1-16 from 11 overs.
The Queensland batting effort made a sound start through Bryce Street (47) and Matt Renshaw (26) before Heazlett picked up the pace. The QAS was 4-119 but steadily began to amass a commanding lead. Heazlett and Wildermuth (26) put on 83 for the fifth wicket before Heazlett and wicket-keeper Lachy Pfeffer stepped up with a 117-run stand for the sixth wicket.
Heazlett's dismissal for 125 saw Pfeffer keep on with the lower order, scoring 78 himself as valuable runs flowed from Steketee (32), Gannon (38no) and Jack Wood, who hit an entertaining 46 from 47 balls.
WA made a better fist of their second innings, although were eventually dismissed for 214 late today, delivering a 205 run outright win for the QAS.
Paceman Mark Steketee was again prominent, taking 3-56, while allrounder James Bazley was damaging late, wrapping up the tail to take 3-23 from 9.4 overs.
Fellow quicks Xavier Bartlett and Cameron Gannon each claimed 2-30.
