The agricultural industry is mourning the sudden death of cattle producer Mervyn Newlands.
Mr Newlands, 28, died when his ute and a B-double truck collided on Warrego Highway near Jondaryan on Tuesday night.
A well-known stud breeder, he was the principal of Lavarta Simmentals at Captains Mountain, where his key focus was improving the genetics of his herd.
Woonallee Simmentals director Tom Baker said while Merv was young, he was extraordinarily passionate about his work and the industry.
"He probably had some of the first Black Simmentals in Queensland, going back seven or eight years ago," Mr Baker said.
"He traveled a lot finding genetics...he was a very big advocate for finding the best genetics and investing in them."
Mr Baker said Merv had bought cattle from Woonallee Simmentals over the years and recalled him once setting an Australian record price of $22,000 for a Black Simmental yearling bull.
"At the time he was a 21-year-old and spending big in the industry," he said.
"He had a tremendous eye for cattle and was a very good stockman.
"He really put his money where his mouth was."
Mr Newlands will be remembered as a dedicated, well-respected passionate member of the industry, who was focused on getting great results with his cattle.
Mr Baker described him as extremely loyal, bluntly honest and a loving father.
"He was a straight shooter and told it how it was," Mr Baker said.
"His passion was rare in somebody so young.
"He was just starting to achieve great things."
