The funding will go towards building accommodation for 130 people.
Dookie Campus director Ros Gall said the university expected the investment to increase enrolment numbers.
“COVID-19 has highlighted the importance of the agriculture and food supply, and the industry is doing well at the moment,” she said.
“The funding is really valuable for the area and makes it much more inviting for students to live and study here and contribute to the region.”
The campus will share the investment with Longerenong College in the Wimmera region and Marcus Oldham's Waurn Ponds campus.
Part of a larger $50 million boost to improve facilities and teaching at agricultural colleges and training providers across the state, the remaining $30 million will create the Future Agriculture Skills Capacity Fund, which will support TAFEs and other agricultural education and training providers.
Agriculture Minister Jaclyn Symes said the funding would help more Victorians pursue fulfilling careers in the industry.
“It's critical we invest in our future agriculture leaders and give them the skills they need to thrive in our growing and exciting agriculture sector,” she said.
“Investing in purpose-built education and training will ensure our next generation of farmers hit the ground running.”
