The win makes it two medals in two days for the 27 year old from Melbourne, after finishing second in yesterday's competition.
In difficult weather conditions, Brockhoff claimed victory in a nail-biting finish, edging out Olympic champion Michela Moioli of Italy by .08 of a second. Rounding out the podium was American Faye Gulini in third.
“It is absolutely unreal! It’s more than just a win for me, I have come back from two ACL blowouts and this is just so huge! I am very happy,” a joyful Brockhoff said.
“The work I have put in over the last two years out of the sport has shown. It’s different for me too, my mind is looking at things differently and its super calm.”
“I had no nerves today. I was calm and patient.”
The podium result is the tenth medal of Brockhoff's World Cup career (4 gold, 4 silver, 2 bronze), and her first win since 2017.
With only two World Cup events remaining, Brockhoff sits in second place on the World Cup standings on 2900 points, 700 points behind leader Moioli.
Adam Dickson was the highest placed Australian in the men's event in 21st position, with Cam Bolton 25th and Jarryd Hughes in 27th.
The next stop of the World Cup tour will be in Sierra Nevada, Spain on March 06-07.
