The British number four is yet to make a sustained impact on the main women's tour, but a 7-6 6-1 win for the 21-year-old will take her into the world's top 140 for the first time.
Veteran Stosur - the 2011 US Open champion - counts grass as her least favourite surface but success for Boulter represents her first major scalp in the professional ranks.
A total of four breaks of serves was recorded in a match which last 76 minutes, and Boulter will now play top seed Ashleigh Barty in the last eight.
There will be two British representatives in the quarter-finals after Johanna Konta registered a hard-fought win over Heather Watson.
