Replacement Teariki Ben-Nicholas scored deep into additional time for the Highlanders to end the Brumbies’ well-documented home run.
Despite being outscored by three tries to two, the Highlanders won the thrilling Round Three match 23-22 in Canberra on Saturday.
It ended the Brumbies’ 11-game winning run at home, as the Highlanders made it five straight victories against the ACT men.
Brumbies hooker Folau Fainga’a scored a hat-trick of rolling maul tries, but it wasn’t enough as they failed to take advantage of a yellow card in the second half.
Highlanders wing Patelesio Tomkinson was extremely lucky to avoid a red card after making no attempt to wrap his arms as his shoulder made contact with Tom Banks’ head in a tackle.
Referee and former Super Rugby player Nic Berry deemed the initial contact shoulder to shoulder and only opted for the sin-bin in the 45th minute, but the replays didn’t look good.
The Highlanders hung tough before Teariki Ben-Nicholas crashed over next to the posts after the siren before Josh Ioane slotted the match-sealing conversion.
The Brumbies were forced to make two late changes with Irae Simone and Darcy Swain ruled out with a virus which saw Caderyn Neville and Lenny Ikitau start.
Lock Nick Frost came onto the bench and 18-year-old former schoolboy sensation Reesjan Pasitoa became one of the youngest players in Brumbies history in the 72nd minute.
It was all the Highlanders early and Ioane slotted a simple penalty to give the visitors a 3-0 lead after five minutes.
But the Brumbies settled and scored on their first attacking opportunity inside the Highlanders 22-metre as Fainga’a crossed for his first in wet conditions.
Consecutive penalties saw the Brumbies earn another five-metre line-out and Fainga’a, the franchise’s leading try-scorer last season, celebrated his second try on 30 minutes.
But the Highlanders immediately hit back from the kick-off when Noah Lolesio was charged down by Jona Nareki who regathered and scored.
Ioane slotted another penalty and the Highlanders took a 13-12 lead into the break before picking up where they left off with another three-pointer in the 42nd minute.
The Brumbies were kept scoreless with their man advantage as rookie five-eighth Lolesio endured a forgettable evening.
Hat-trick hero Fainga’a scored his third and a Ryan Lonergan-penalty made it 22-16 in the 74th minute.
The Brumbies had the ball with 15 seconds remaining but the Highlanders won a ruck penalty before breaking the hearts of most of the 7270 fans.
