This month, the Horsham Regional Livestock Exchange celebrated its 20-year anniversary.
The saleyards moved from the Horsham city centre to Burnt Creek Industrial Estate in 1999.
It was officially opened on December 1, 1999, with its name changing from the Horsham Saleyards to the Horsham Regional Livestock Exchange.
It is the fourth-largest lamb market in Victoria and averages about 500,000 head each year.
Horsham Regional Livestock Exchange manager Paul Christopher has been involved with the livestock exchange for 14 years.
"It's grown since I started; we've seen really good numbers, the highest being 627,000," he said.
"Just like any other farming business it goes up and down depending on drought."
The livestock exchange celebrated 10 million head through in September 2018.
Mr Christopher estimated that it was now 10.5 million.
"Our area is predominantly cropping now, while Hamilton saleyards does something around one million each year," he said.
"We've had some amazing lamb prices this year up to $300 [a head].
"Records were breaking every week for a while there and that was reflective of the national flock which was significantly down."
Ian Crafter's company Atlex Stockyards was awarded the tender for the saleyards project in 1998.
He managed and operated the saleyards for eight years until December 2007 when it was handed over to Horsham Rural City Council.
Mr Crafter grew up on his family's farm at Longerenong.
"Our family bought and sold through the old saleyards on Darlot Street, so I always had that historical involvement," he said.
In 1998, the council awarded Atlex a contract to design the new saleyards.
Atlex was also the successful tenderer for the construction of the saleyards at the cost of $3.2 million for the complete build.
"We started construction in May and finished in November," he said.
"We built all our yards on the farm at Longerenong, the whole saleyards were built locally by local people.
"It was the most harmonious project that I've ever done.
"We all had a real sense of purpose and wanted to do the best job we could, I'm very proud of it."
A contract has been awarded for the exchange's roofing project, with total cost estimated at $3.692 million.
Horsham councillor and livestock exchange advisory board chairman David Grimble said work at the site had already started and the project would be completed by the end of 2020.
"The challenge for us will be maintaining it as an operating exchange during the construction period," he said.
