Joshua Leigh Dudley Dendulk, 39, remained in a distressed state when he applied for release at Wollongong Local Court on Wednesday after he was taken into custody following the stand-off.

Documents tendered to court said officers arrived at his Robert Cram Drive home in Bellambi about 10.50am to speak to Dendulk about an alleged breach of his bail.

As they left the home as no one was answered the door, they spotted Dendulk in the front passenger seat of a black Hyandai Tuscan.

Police followed the car back to the home, parked and got out of the car where Dendulk then allegedly started to run towards the front door.

It is alleged the uniformed officers yelled for Dendulk to stop and announced they were police officers but Dendulk continued to run before he pulled out a large 30 cm kitchen knife with a brown handle.

Dendulk allegedly turned to challenge the officers to shoot him whilst still holding the knife in his right hand and was gesturing it towards them.

Police then allegedly drew their guns as they feared they were in danger before Dendulk was allegedly directed to drop the knife.

Dendulk allegedly refused and yelled for the officers to get away from him before he went inside the house and closed the door.

The officers called in reinforcements, set up a perimetre around the house and attempted to negotiate with Dendulk and requested he come outside but he refused.

Dendulk and the officers including multiple specialist resources and emergency services were involved in the stand-off for four-hours.

During the siege, police continued to negotiate with Dendulk who came out onto the second-storey balcony, allegedly ranting at police and he appeared to be in a manic state, the documents said.

The police also said a woman was inside the house, who refused to come out, but she did not appear to be there against her will.

Dendulk left the home about 2.45pm before he was arrested by specialist police.

He was taken to Wollongong Police Station where he was treated by paramedics who took him to Wollongong Hospital for mental health assessment.

He was not scheduled and later returned to the station where he was charged with intimidating a police officer in the execution of their duty; resisting or hindering a police officer in the execution of their duty; using an offensive weapon to prevent lawful detention and being armed with intent to commit indictable offence.

The documents also said this alleged incident was the third time Dendulk had been involved in a siege situation with police.

In court, defence lawyer Rosie Lambert said her client thought he was getting "robbed" when the police officers got out of an unmarked grey four-wheel drive in what he claimed was standard police uniform.

Ms Lambert said Dendulk was in a "paranoid state" at the time police arrived and he had a "panicked reaction".

She also said Dendulk admitted to causing most of his injuries himself, which including a swollen black eye.

Ms Lambert claimed the prosecution case was weak, telling the court police had no right to tell him to "stop" because they had no reasonable suspicion Dendulk was committing an indictable offence and was not breaching his curfew condition of his bail.

She went to say what followed as a "escalation" and a "regrettable," "distressing and terrible incident" for all involved.

Ms Lambert also said Dendulk's family, who were in court, would take him straight to hospital for reassessment if he was released.

Dendulk repeatedly spoke through the proceedings and said he was "scared" and he was "begging for help".

Police prosecutor Sergeant David Weaver said police attended the home to investigate why Dendulk allegedly did not report to the police station for bail, for an unrelated offence, on May 30 and 31.

Sgt Weaver conceded Dendulk did attend the police station on Monday claiming he had a medical certificate explaining why he didn't report the previous day however said police were continuing their inquiries.

He disagreed with Ms Lambert's submission and claimed the officers, who were in uniform and announced who they were, went to the house in "good faith" to investigate the alleged breach of bail and were entitled to tell Dedulk to stop, before he allegedly pulled a knife on them.

"He turns, draws the knife and threatens them with it," Sgt Weaver said.

"He then barricaded himself inside the house that resulted in a four-hour siege, which was a huge waste of police resources."

Dendulk was refused release with Registrar Bruiceen Coulthard ordering he be reassessed for an admission to a mental health ward given he was clearly distressed during the court proceedings.

He may return to court following that assessment.
