Daniel Thomas Mooney, of Horsley, is accused of sneaking into the elderly woman's room several times before bending the physically disabled patient over her bed and assaulting her.

Opposing the 41-year-old's bail application yesterday, police prosecutor Anna Comer said there was a need to protect the community from the alleged sexual predator.

The court was told the elderly woman had a host of disabilities.

Police claim Mooney, who had worked at the home since 2004, first molested the woman on September 21, entering her room about 4am.

Another carer entered the woman's room and found the patient bent over the bed with Mooney standing directly behind her, the court was told.

On October 31, Mooney allegedly again entered the woman's room and assaulted her.

Another carer later opened the curtains around the woman's bed to find Mooney allegedly standing nearby, looking hot and sweaty.

Police claim the patient was clinging to the bed rails, without any underwear, and had a hand print on her stomach.

Just two hours later, Mooney allegedly returned to the woman's room and assaulted her again.

Senior management were notified of the incidents and Mooney was suspended.

Mooney participated in two interviews with police earlier this month and initially denied any wrongdoing but later allegedly admitted to sexually assaulting the woman.

He was charged with two counts of aggravated sexual assault of a victim with a physical disability and one charge of aggravated indecent assault.

Defence solicitor Angela Melouney told the court Mooney had no criminal record and would stay away from the nursing home.

Ms Melouney said her client could live with his mother, would report to police and had strong community ties.

Magistrate Michael Stoddart refused bail, noting the allegations were serious.

He adjourned the matter to January 9 next year.
