The Brumbies have struck, with a 38-13 win over the Sharks to move into a Super Rugby semifinal next weekend against the Jaguares in Buenos Aires.
Forward Peter Samu scored two tries to lead the resurgent Brumbies to a seventh consecutive win.
The Brumbies advanced to their first Super Rugby semifinal in four years, ensuring an Australian presence in the semis.
"I'm really proud — the Sharks threw a lot at us and the way the boys kept digging deep for each other was special," Brumbies captain Christian Leali'ifano said.
