TWO women and a man have admitted performing sexual acts with an animal.

Tina Marion Reichelt, 52, Garry Paul Reichelt, 51, both of Clare, and Kathleen Modystack, 58, of Ovingham, appeared in the District Court yesterday.

The court heard each had previously pleaded guilty to one count of bestiality on November 25. Court documents show the offence occurred at Ovingham between November 2008 and May 2010. They do not detail the species of animal involved.

The maximum penalty for committing bestiality is 10 years' jail. Garry Reichelt's lawyers said they were awaiting a psychologist's report before sentencing submissions.

Alexandra Wright, for Tina Reichelt, said she had received a report about her client's mental health but was waiting to settle matters with the Office of the Director of Public Prosecutions.

Adelaide Magistrates Court documents reveal there were previously more charges of bestiality against each defendant that were dismissed in November.

Judge Geoff Muecke remanded them on continuing bail.
