The wild animals have been creating havoc for residents and disrupting traffic for the past 12 months

Fed-up locals in Adelaide’s north say they’ve been besieged by up to 50 feral sheep taking over roads and gardens while authorities pull the wool over their eyes.

A flock of wild sheep has been on the loose, terrorising residents in Adelaide’s northern suburbs, fed up locals say.

7News Adelaide reports around 50 sheep have been roaming the city’s north and northeast, helping themselves into residents’ gardens and disrupting traffic.

Homeowner Lauren Bell told 7News she thought the sheep were ‘breeding’ and would continue to “wreak havoc” across the northern suburbs if not dealt with.

“They come into our front yards, backyards, run across our roads, confront our residents in their own properties, knock down our retaining walls, eat through our veggie patches,” she said.

Ms Bell said she had nearly hit sheep while driving on Blacktop Road, with video footage showing multiple sheep crossing the road into a neighbouring property.

“Our patience is wearing thin and we want to see some tangible evidence of something being done in this space,” she said.

Her neighbour Karen Jarrett said she found a ‘threatening’ big ram with horns in her garden.

“We managed to corral him out. It took us about an hour to get him out of our garden,” Ms Jarrett said.

“You get onto the authorities just hoping for some help but we just haven’t had anything. Just a lot of lip service.”

FIVEAA radio also reports that the flock have been found roaming Hillbank, Greenworth and Tea Tree Gully, and have been on the loose for the past 12 months.

The Playford council said they have captured and relocated more than 40 unowned sheep and have urged residents to be “diligent in their private land and property”.

The flock are believed to be wild and have been wandering through properties on the daily.
