Shayne Allan Roberts, 37, was charged with contravening an apprehended violence order, intimidation and common assault over the alleged Christmas Day incident.

Documents tendered to Wollongong Local Court said Roberts went to his former partner's Kiama Downs home about 5am after being released from custody for an unrelated matter.

The woman invited him into the home but a short time later they began arguing.

The pair continued their verbal argument outside before the woman returned indoors, promptly followed by Roberts.

Roberts' language became more aggressive and he started calling the woman derogatory names.

While she was lying down on the bed Roberts allegedly said to her, "I'm going to slit your throat and watch you bleed out" before adding, "wait till my family finds out what you've done."

The woman alleged Roberts forcefully thrust his thumbs and knuckles into her eyes, causing her pain, while he was threatening her.

Roberts eventually stepped away from her, which gave the woman the opportunity to call Triple 0. Roberts left in his car before police arrived.

Officers spoke to the woman a short time later, noting she was "very upset and distressed", the court documents said.

Based on the woman's statement immediately following the incident, police allege Roberts breached his apprehended domestic violence order - which prohibits him from assaulting and intimidating her - within minutes of being released from custody.

The following day police went to Roberts' father's Greenwell Point home but Roberts was not there.

Roberts and his father went to Nowra Police Station voluntarily a short time later where he was arrested.

Roberts denied the allegations when questioned by police, and he claimed the woman became aggressive towards him. He was later charged.

On Monday, the court heard Roberts had no prior convictions and denied breaching the apprehended violence order, claiming he did not harm the woman, defence lawyer Jack Hibbard said.

Mr Hibbard also said his client needed to be at liberty to care for his elderly father.

Police prosecutor Sergeant Ben Bragger said police were concerned there could be further "flare ups" of violence over the holiday period between the pair.

Registrar Darcy granted Roberts bail as he could stay well away from the woman at his father's home.

The case was adjourned to next month.
