Queensland leap-frogged Victoria into third spot with the six-wicket win under gloomy skies at Allan Border Field.
The win has them one point behind second-placed WA, although other results in the remaining rounds this week as well as the weather could ultimately determine the top two.
NSW survived a scare today at the hands of Tasmania, winning off the last ball with the final batting pair at the crease, to stay on top of the table.
A fine all-round effort from Grace Harris today ensured victory, with the allrounder warming up for her appearance in the Bushfire Bash charity game at the SCG on Saturday.
Harris claimed 3-28, while pace bowler Holly Ferling, who will also feature in the Bushfire Bash, had 2-28 from her 10 overs.
Harris hit a six to win the match, finishing 53 not out, as she and Hinkley (52no) put on an unbeaten match-winning stand of 107.
Victoria were dismissed for 181 from 50 overs, with the Fire chasing down the total in the 37.1 overs.
Teenage debutant Georgia Voll picked up 2-11 from her three overs, bowling at an important time after a Harris run-out had removed Victorian trump Elyse Villani (55).
Victoria play last-placed South Australia tomorrow before Queensland play the Scorpions on Thursday.
