A critical shortage of rural workers may have allowed the theft of 5,500 sheep worth an estimated $1.7 million to go undetected for several months on an outback Queensland property, authorities and industry leaders say. Police believe the dorper ewes and rams were stolen from a property on Blackall-Isisford Road sometime between February and May, though how the animals were removed without detection remains a mystery.

The Scale of the Sheep Theft

The sheer number of animals involved has left investigators puzzled. AgForce Queensland general president Shane McCarthy said that removing 5,500 sheep in a single operation would have required extensive logistical planning, multiple transport vehicles, and the coordinated efforts of several people.

"A mob that size would take a lot of logistics, a lot of trucks. There's more than one person involved in that many sheep going missing," McCarthy said.

Investigators are working to determine whether the flock was taken in one large, coordinated operation or gradually removed in smaller groups over the three-month window. McCarthy noted that repeatedly moving smaller numbers of animals across that period could have been considerably easier to conceal from property owners and neighbours alike.

The missing sheep were fitted with white National Livestock Identification System (NLIS) tags, which are designed to track animals as they move through the supply chain — a detail investigators hope will assist in tracing the animals' whereabouts.

Rural Worker Shortages Under the Spotlight

McCarthy pointed to the immense scale of outback properties combined with declining numbers of on-ground workers as a key reason such a large theft could go unnoticed for so long. With fewer staff regularly checking on livestock across vast land holdings, the absence of thousands of animals may simply not register for weeks or even months at a time.

He also warned that Queensland's Rural and Stock Crime Squad appears to be confronting a growing wave of farm-related theft more broadly, not limited to livestock alone.

"Unfortunately, they seem to be getting more and more incidents of these types of things happening, stock going missing, whether it's cattle, sheep or goats, and also theft on farms of fuel, machinery, equipment," McCarthy said.

Investigators Seek Public Help

Detectives from Queensland Police's Rural and Stock Crime Squad are leading the investigation and are urging anyone who observed suspicious livestock movements, unusual stock transport activity, or any other out-of-the-ordinary behaviour near the property to come forward.

McCarthy expressed cautious optimism that the animals would eventually be located. "We'll hopefully find them. They'll turn up somewhere. Somebody knows something," he said.

Anyone with information is asked to contact the Rural and Stock Crime Squad at Longreach or reach out through Crime Stoppers.
