Peter Siddle returned with a four-wicket haul to help Victoria bowl out Wayamba for a paltry 106 after Jehan Mubarak won the toss and elected to bat.
David Hussey (47) and Aaron Finch (38) then shared an unbeaten 47-ball 77-run third wicket partnership to overhaul the target with 6.4 overs to spare as Victoria moved to the second spot in the points table of Group A.
Victoria's brilliant run-chase have also improved their run-rate but the road to semifinals will depend on the result of the match between the Warriors and Chennai Super Kings at Port Elizabeth on Wednesday.
