A goal to American import Veronica Latsko and a Natasha Prior own goal was the difference as the Lady Reds held on in a solid performance to claim all three points and move to second spot on the ladder.
With two wins and a draw from their opening three games, Adelaide move to second on the W-League ladder behind competition leaders
Impressively Adelaide's defence has shown once again that it is the best in the competition as keeping a clean sheet in all three of their matches this campaign.
Latsko opened the scoring after 27 minutes for the home side when she snuck in behind the Canberra defence to finish a pinpoint cross from Michelle Heyman.
The visitors were determined to find an equaliser with Matildas rising star Ellie Carpenter a constant threat.
Both sides had their fair share of chances in the second stanza, but it would be Adelaide who would take advantage when the doubled their lead late in the match.
Latsko's shot from inside the box was smothered by the Canberra shot stopper but the ball would ricochet off her and onto the legs of teammate Prior before rebounding into the back of the net.
Adelaide will be tested up against reigning W-League champions Melbourne City next week when they travel to C.B Smith Reserve, while Canberra will return to their McKellar Park home ground to take on Sydney FC.
