Ms Thomas said the funding would make a difference for the community.
"Families in Kyneton have done a phenomenal job in supporting students to learn from home," she said.
"As kids return to their classrooms, we want to make Kyneton High School better than before.
"Not only will this make sure our kids are getting a great education - it'll create new local jobs."
Education Minister James Merlino said this was investment in the children's future.
"Every child, no matter where they go to school, deserves access to state-of-the-art facilities," he said.
