Business Horsham chairman Robin Barber has urged the community to rally at Horsham College to show support for the escalating campaign to rebuild the ailing college buildings.

Mr Dixon will visit Horsham Special School at 10am and is due at Horsham College at 10.45am, before meeting Horsham Rural City Council at noon.

He will also visit Horsham Primary School's Rasmussen Road campus.

Mr Barber said Mr Dixon would tour the college with Member for Lowan Hugh Delahunty and Business Horsham representatives.

He asked all community members, especially parents of students, to attend an organised rally in support of the Rebuild Horsham College campaign.

Horsham College has buildings dating from the 1950s and some students will be in temporary classrooms from next month after the school missed out on state funding for upgrades, including a new library. The Claude Brand Library caught fire on April 22 last year, causing damage estimated at $1 million.

Horsham Special School was funded to be built on the college site and college buildings will be demolished in March.

Music, science and home economics classes will be in temporary classrooms, which are being refurbished for the purpose.

Students are already using a temporary library and study centre.

"I will be disappointed if we don't get 1000 people at the school's front gates in Dimboola Road, Horsham, on February 22," Mr Barber said.

"Everyone is to bring their colourful banners and good manners."

Mr Barber said the State Government had ignored Horsham College, and the Wimmera, for too long.

"Now is the time for us to be heard," he said. "Mr Dixon's visit is a unique opportunity for as many people as possible to help strengthen the campaign towards this extremely important cause.''

Mr Barber said it was imperative the community’s voice was heard on Horsham College, the largest state secondary school in the region.

“A massive show of hands at the rally will hopefully leave an indelible mark on Mr Dixon’s mind as to just how important this school is to our community,” he said.

Mr Barber said the standard of Horsham College’s buildings was a disgrace.

“If we want our city to prosper, grow and attract people then we must have better facilities,” he said.
