STARVING horses and several carcasses have been discovered on a Greymare property off the Cunningham Highway west of Warwick.
The grisly find was made by local horse owners who pass the property on their way into Warwick.
After watching the animals suffer slowly for weeks the concerned couple decided to enter the property to check on the animals' welfare.
"My husband entered and found a mare floating in the dam," said the Good Samaritan, who did not want to be named.
On further exploration of the property the couple discovered up to six carcases, with one dead and caught in a fence another floating in a dam, still wearing its blanket.
"They have not had food for a good month or more, and no water," the woman told the Daily News.
The couple soon contacted the both the RSPCA and the Southern Downs Regional Council in the hopes of rescuing the nine surviving horses.
"I haven't been able to get in contact with anybody," the woman said, who launched a Facebook campaign in an attempt to feed the animals.
A farmer on the neighbouring property said he hadn't seen the owner for months.
Council representatives waited outside the property for authorisation from the RSPCA, while a local horse owner enraged by the Facebook photos came to throw feed over to the animals.
She pointed out a thin yearling foal in the distance: "It shouldn't look like that, there is no excuse".
An RSPCA Queensland spokesman confirmed they had previously attended the property before Christmas on a case involving other animals.
At the time the owner allegedly said he would "solve the situation".
"But that doesn't seem to be the case according to reports," the spokesman said, stating the case was "certainly a concern".
"We received the complaints and passed this issue onto Biosecurity Queensland due to the sheer number of animals," he said, adding the RSPCA lacked facilities to hold the horses.
Biosecurity Queensland is now "investigating reports of a possible animal welfare situation on a property at Greymare involving a number of horses".
"No specific comments can be made about this case while the matter is under investigation," a spokesperson said.
Under the Animal Care and Protections Act 2001 all persons in charge of animals have a duty of care to ensure the animals receive appropriate food, water, living conditions and treatment for any disease or injury.
The Daily News attempted to contact the owner for comment but was not available.
