ORGANISERS of a Sustainable Land and Living Expo at Longerenong College are considering making the event annual following its success at the weekend.

College development officer Donna Winfield said hundreds of people attended the expo.

"It is something we will be looking at doing annually from now on," she said.

"We had people travelling from places like Ballarat, St Arnaud, Bendigo and Castlemaine which was great to see."

Mrs Winfield said Melbourne environmental campaigner and author Tanya Ha was a highlight for many people.

"Tanya was a huge hit because she really interacted with people," she said.

"When she arrived she mingled with the crowd and exhibitors and gave them some tips.

"It was more about her learning from being there on the day so she could take it back from the paddock to the city.

"She was able to explain how one person can make a difference to the environment and she was very engaging and signed some copies of her book too."

Mrs Winfield said all the exhibitors were very impressive.

"The Segway demonstration was amazing, people were able to ride on those, and there was a nice range of exhibitors from organic food to solar power," she said.

"I really enjoyed the landscaping exhibitors who talked about how even though there is no water, things can still look nice."

Mrs Winfield said it was good to see a group of people taking on the environmental challenge.

"La Vergne Lehmann from the college went into their homes and gave them some tips about becoming more environmentally-friendly while saving money and water," she said.

"Those people won some fantastic prizes by taking on the challenge and looking at some ways of making a difference."

Mrs Lehmann said Graeme and Shirley Meyer, Nicholas and Julie Kitchen, Helene Vanderwaal and Helen and Brett Symes took on the challenge.

"The Symes won the washing machine," she said.

"We looked at how to improve their house in terms of sustainability without spending lots of money and we looked at things like solar hot water."
