Business development officer Donna Winfield said it was a fantastic for the college.

"It was a great day, we had a lot of people travel a very long way in really cold conditions," she said.

"Highlights of the day for people included our show steer parade, taking tours around the farm and listening to the exciting things that Longy has to offer."

Mrs Winfield said people were particularly interested in the new DATA farm project at the college.

The college received $3.6 million last year to established the AgTIDE Demonstration of Agricultural Technology Applications Farm project.

The project will establish a digitally-enabled, 1000-hectare demonstration farm to test and analyse new digital agricultural technology in the grains industry.

People were also able to tour the college accommodation and living areas.

The show steer team used the open day as an opportunity to practice their handling skills ahead of the Melbourne Show next month.

Mrs Winfield said people also wanted to hear about the many career opportunities that agricultural had to offer.

The enrolment process has now started for next year.

"We had people travel a long way, some who have been before and some who hadn't," Mrs Winfield said.

"We've already received quite a few enrolment applications for next year and they will keep flowing in for the rest of the year."

The day was largely ran by second-year students, who led tours of the college and talked to prospective students and their parents.

"These students really come into their own and rely on all the skills they have learnt over the past two years," Mrs Winfield said.

"Their leadership skills came into play and I'm really proud of them.

"We received a lot of positive comments from parents saying they were blown away by how these students acted and how proud they were of their college."

Mrs Winfield said anyone who missed the day could attend an information day at the college on December 6.
