Webb made her WNCL debut for Tasmania in the first match of the 2017–18 season, scoring four runs with the bat and finishing with bowling figures of 2/28 in a seven-wicket loss to Western Australia.

[14] Her most significant contribution of the season came on 29 December at Docklands Stadium, when she scored 21 not out and helped the Renegades narrowly defeat the Melbourne Stars with one ball to spare.

[17][18] She delivered a breakout performance on 17 November 2019 against the Sydney Sixers at Drummoyne Oval by scoring 34 not out, hitting a six off the final ball to clinch a two-wicket victory and earning Player of the Match honours.

[19][20][21] Although her team struggled throughout WBBL|06, Webb was again recognised as one of the league's rising stars—an unbeaten innings of 54 runs from 33 balls at Sydney Showground Stadium on 15 November 2020 helped secure a super over victory against the previously undefeated Melbourne Stars, earning her a second nomination for the Young Gun award.

[31] Despite injuries and the struggle to balance two sports, it was reported she would continue to play football at local level for Launceston and hadn't ruled out attempting to return to AFLW in the future.
