Police are investigating the disappearance of 2442 sheep from a rural property on the Eyre Peninsula.

Between August and December this year, 2442 sheep of mixed age and breed have gone missing from the property, located between Bookabie and Fowlers Bay.

The property, on the Eyre Highway about 60 km west of Penong, is bordered by the Yalata Aboriginal Lands, the Eyre Highway and the Dog Fence.

The sheep were last sighted in the Yumbara Conservation Reserve during an aerial search in August, but have not since returned to nearby water points. It is not known if the sheep have been stolen.

On Thursday 26 December, the property owner reported that a gate accessing the Eyre Highway had been cut open using wire cutters. The gate had just been inspected and secured on Tuesday 24 December. Police observed fresh tracks at the gate indicating a vehicle and trailer had recently been in the area. It is not known yet if any stock are missing from that yard.

Farmers with livestock are encouraged to maintain accurate records, count stock regularly, restrict access to stock yards and report any missing stock or suspicious activity in a timely manner.

Anyone with information about the missing sheep or any suspicious vehicles in the area are asked to contact their local police station or by ringing 131 444.
