Cattle should enter the Upper Lachlan Shire on Saturday (November 9) or Sunday (November 10).

The mob has been grazing in the Hilltops region, around Boorowa, since early October.

There are about 1200 head of cattle grazing the stock routes in the south-east district; another 500 are grazing routes in the Monaro.

Permits are issued for areas with large amounts of roadside feed, and with low biosecurity and public safety risks, including high-volume traffic areas.

South East Local Land Services mitigate bio-security risks and work closely with the drovers.

Senior bio-security officer Matthew McNaughton said it was difficult to forecast the exact movements of the travelling stock along stretches of local roads.

He reminded motorists to slow down and use caution when approaching the mob.

"The mob will be grazing around the Narrawa, Wheeo and Biala areas," Mr McNaughton said.

"Then moving on to Gurrundah, Bannister, Pomeroy, and Parkesbourne.

"The cattle will enter the area on the Boorowa Road and will be travelling along Wheeo Road."

Other roads in the district the mob will use are: Sapphire Road, Biala Road, Grabben Gullen Road, Gurrundah Road, Bannister Lane, Storriers Lane, Range Road, Lambs Lane; Pomeroy Road, Gurrundah Road, Merilla Lane, Henry Parkes Road, Wesley Road, Church Hall Road, School House Lane, Breadalbane Road, Church Hall Road, Parkesbourne Road, Gap Road, Gurrundah Road, and Bannister Lane.

Multiple 'cattle ahead' road signs will be displayed on the roads within five kilometres either side of the travelling stock. The mob will be walked between sunrise and sunset and yarded overnight in a secure holding paddock or freestanding break.
