South West residents have expressed outrage following a series of alarming incidents over the past few weeks.
Leschenault resident Symone Ferriday has been raising her horses on a property near the estuary since 2013.
Rachael Mead began training her horses on the same property 12 months ago.
The property's tenants and some of its neighbours have reported a spike in animal cruelty incidents in the area.
Most recently, a kangaroo was shot and left to die in one of the property's two paddocks - just 50 metres from the residence.
"The kangaroo was very far away from the road. It worries me that they [the culprits] have either come up the driveway or taken a shot from the road," Ms Ferriday said.
Another incident saw Ms Ferriday and Ms Mead's horses being let out, allowing them to exit the premises and run out onto the road.
"I was in Busselton, and I got messages from Rachael and a couple of other people saying that my horses were on the road," Ms Ferriday said.
"Fortunately everyone around here looks out for one another, so some of the neighbours chased the horses back onto the property."
On two other occasions residents found the remains of decapitated swans and one goose in the area.
"Seeing a goose with its head chopped off was also pretty devastating," Ms Ferriday added.
Ms Ferriday and Ms Mead said they were both extremely saddened and frustrated by the rapid escalation in such acts of violence.
"I have chased people out of both paddocks before...it's becoming more frequent and consistent, and the level of brutality is getting worse," Ms Ferriday said.
"It is devastating to watch such a beautiful area being turned into a place where people hunt animals for sport."
Roo Rescue founder Kim Grant also said she was disappointed and furious with those responsible for the incidents.
Ms Grant revealed she has responded to numerous reports of animal cruelty in the South West, including Leschenault and Australind.
She and the Department of Parks and Wildlife are urging those who witness any suspicious wildlife-related activity - or wish to report sick, injured, or orphaned native animals - to contact the Wildcare Helpline on 9474 9055.
Australind Police were contacted but were not able to respond in time for publication.
