It was referred to the video referee as a no-try, and while it appeared as though Waqa had grounded it on the line, there wasn't enough evidence to overturn the decision.
Raiders fullback Anthony Milford was sensational, as was his opposite Billy Slater, who would've busted the game wide open if it wasn't for some desperate defence by Croker - who made no less than three try-saving tackles.
The Storm's short and long kicking game was at its pinpoint best, setting up the opening two tries and catching Milford out of position twice in the first half.
Storm forward Ryan Hinchliffe opened the scoring in the ninth minute after pouncing on a Cameron Smith grubber that had rebounded off the post.
The Raiders struck back through centre Matt Allwood in the 15th minute, but the Storm skipped away again through tries to Waqa and Mahe Fonua.
The home side kept in touch on the stroke of halftime when winger Reece Robinson finished off a crazy try that wouldn't have looked out of place at a Harlem Globetrotters match, narrowing the gap to 16-12.
Fonua, a late inclusion into the side for the suspended Will Chambers, picked up his second of the match not long after the break, but it didn't take much longer for Robinson to do the same for the Raiders.
Waqa was then denied his second try twice by the video referee, which would eventually allow the Raiders a sniff at the win.
