Acting Prime Minister Warren Truss, Deputy Premier Peter Ryan, Member for Mallee Andrew Broad and Member for Lowan Hugh Delahunty announced $2 million to refurbish the college's student accommodation on Friday.

The refurbishment will include upgrading 108 student rooms, six disabled access rooms and shared residential areas such as bathrooms, kitchens, lounge rooms, the laundry and pathways and stairwells.

A new three-story building will be built, which will adjoin the accommodation.

It will include two new communal study areas and separate recreational area.

New air-conditioners will be installed, the wireless internet will be upgraded and the hot water service will be replaced.

Longerenong College chief executive John Ackland said it had taken five years to receive the money.

He said student numbers were growing by 10 per cent each year.

"We need agriculture for the future of the region and if we don't train students in agriculture, there is no future," he said.

"Next year we will have to cap student numbers, which is amazing given that eight years ago we only had about 30 students, and now we are nearly full."

College general manager John Goldsmith said the new accommodation would not allow the college to increase student numbers.

"It just means we can better accommodate the students we have," he said.

Mr Broad said the money was a fantastic result for the college. 

"I toured Longerenong as a candidate and I was very impressed with the culture of the college and its students," he said.

"As soon as I got back to my car from the tour I thought to myself, a first-world agriculture centre deserves first-class accommodation and noted that if I was successful in the election, I would deliver the much-needed upgrade to the college." 

Mr Truss said agriculture education was important for the country.

"Longerenong College is one of Victoria's leading agricultural education and training centres and is the only educational centre in the region that offers agricultural training and on-site accommodation," he said.

"The college delivers hands-on training through its 1070 hectares farm, which is complete with cropping, sheep and beef cattle enterprises, and offers students a wide variety of courses such as shearing, truck driving, header operation and farm management among others.

"It is essential we have a regular infusion of young people in agriculture because if we want to have strong agriculture in this country, we need the young people to come forward and push the industry to its full potential.

"It is important the Longerenong College ensures the next generations of farmers do better than their forefathers so we can remain competitive internationally."

Longerenong College would provide $1.4 million towards the project.
