Richie Porte (BMC), Sergio Henao (Sky) and Michael Woods (Cannondale) were all active on the ascent, but it was three-time TdU winner Simon Gerrans (Orica-GreenEdge) who prevailed in the final sprint to the line in Campbelltown, narrowly beating defending champion Rohan Dennis (BMC).
British hope Geraint Thomas (Sky) slipped back on the climb, with Sky leadership now allocated solely to Colombian Henao.
Gerrans moved into the overall race lead after his stage victory, with overnight leader Jay McCarthy (Tinkoff) keeping in touch with the leaders on the stage to position himself in second place overall, with Dennis in third.
The 2016 Tour Down Under concludes on Sunday, January 24.
