MARBURG Show president Robert Krause introduced dairy farmer of the year Greg Dennis to formally open the 94th Marburg Show, saying Australian farmers were some of the most efficient in the world.

"They had to become that by overcoming challenging situations where they had to invent and be better at what they were doing as the years went on," Mr Krause said.

"In some ways that's what Greg Dennis has been doing."

Mr Krause said Mr Dennis faced a formidable challenge in his own area of dairy farming.

"He has attacked his challenges in a technical way and also in a marketing way."

Mr Dennis said the moving of the Marburg Show date in the calendar a year or two ago was a master stroke, delaying the show by a week and avoiding last weekend's poor weather.

"I think it is important to recognise how important these events are," Mr Dennis said. "Marburg is a small town much like my own home town of Beaudesert.

"There are lifelong memories the kids are going to get coming here year after year and you just can't replace those memories that become part of our life experience."

Mr Dennis said he was aware of the stigma in being labelled a farmer.

"The problem is people have the wrong perception of what farmers are, what we're about, what we do," he said.

"We provide a service, we provide fresh food to Australia and that's going to become more important.

"If we surrender our safety and sovereignty around food production, that's a scary proposition for Australia."

Mr Dennis said it was great driving into town to find out Marburg was voted the friendliest town in the country in 2008 and he had judged the dairy section of the show in 1992.

"It's good to come back," he said.

Marburg Showgirl Steph Knight said the show went really well.

"We've got great weather and a good crowd," she said.

Ms Knight will represent Marburg in the regional show girl competition in Esk in July.
