Spratt attacked over the top of the Corkscrew climb and opened up a promising gap.
She needed more against Brown, however, who started the stage six seconds ahead of Spratt coming into Tuesday’s finale in the 93.2km third stage from Adelaide to Campbelltown.
Spratt, who showed her cards on Monday’s stage with a searing attack that was reeled in, put in a brutal acceleration to split the lead group.
Brown gave chase and kept her compatriot on a tight leash. The FDJ rider put up the chase on a technical descent and caught Spratt under the red kite.
Brown powered to the line, with Spratt settling for second. The pair finish in the same order on GC. The chase group came across 13 seconds back.
“I’m elated. It feels so good, I knew the climb would be a challenge because Amanda (Spratt) is a bit more of a climber, I just needed to keep her within reach,” Brown said. “I planned before the stage to put some bigger gears on my bike, so I could keep pushing on the descent.
“I was able to for the last 3kms, I could see her, and then I thought if I could catch her and then, I
decided to sit behind her in the last kilometer and I was fairly confident I could jump her in the sprint.”
