Having been the Officer In Charge at Roma for the past 23 years, Mr Wilby, more commonly known as Jim, oversaw his final store sale on Tuesday.

After 35 years of loyal and dedicated service to the Queensland Police, Jim was proud to report that Australia's largest store cattle selling centre had very few incidents of livestock crime occurring.

"I feel the key to success in this job was to get out of the office and go a talk to cattle producers and the community at large," he said.

Meanwhile, a total of 7000 head were yarded this week with cattle prices remaining firm, according to saleyard reporter Penelope Arthur.

Agents said it was a mixed quality yarding with young cattle values lower than last week's record highs.

Elders Roma livestock agent, Mick Connell, said cattle numbers should remain at current levels until clear evidence of a good summer season has eventuated.

"The sale started slightly cheaper for the plainer type cattle, but values increased as the sale progressed," Mr Connnell said.

"A full panel of buyers was hanging back during the early part of the sale, but they finished very strong."

Overall, feeder steers were fully firm at a top of 206c/kg, while the best weaner steers were slighter cheaper than last week and sold to a top of 228c.

"In the medium term, cattle numbers coming into Roma sale should start to slow down during the warmer months and producers in northern Queensland are expecting a break in the season in the near future."
