The 126.5 km final stage from Norwood to Campbelltown was built around the double ascent of the Category 1 Corkscrew Road and was always going to decide the GC. Carina Schrempf and Mikayla Harvey built a big early lead — at one point almost six minutes — before the GC teams reeled them in on the approach to the climb.

The instant the road pitched up for the first time, race leader Ally Wollaston was dropped, ending her overall hopes and splitting the race apart. A select group formed over the top featuring UAE Team ADQ's Mavi Garcia and Dominika Wlodarczyk, plus Sarah Van Dam and Noemi Rüegg. On the descent and run-in, Garcia and Wlodarczyk combined to isolate Van Dam before Wlodarczyk went clear alone.

Wlodarczyk carried a small lead into the second Corkscrew, but Rüegg — earlier paced back to the front by world-champion teammate Magdeleine Vallières — bridged across, bringing Garcia and Blasi with her and leaving herself outnumbered three to one. UAE attacked repeatedly on the climb and descent, but Rüegg followed every move. The four reached Campbelltown together, and from 500 m out the Swiss rider produced the fastest sprint to take the stage and the title.

Winning the stage and its bonus seconds, Rüegg seized the ochre jersey on the final day to finish 11 seconds clear of Mavi Garcia, with Paula Blasi third overall at +0:14 and Dominika Wlodarczyk fourth at +0:17 — a UAE Team ADQ lockout of the next three places behind the champion. Sarah Van Dam was fifth at +0:25. Wollaston, dropped on the first Corkscrew, lost the lead but retained the points classification, while Blasi took the Queen of the Mountains jersey. Rüegg became the first back-to-back Women's Tour Down Under winner since Amanda Spratt in 2019.
