A 37-year-old man has been charged following a Mangerton street fight that allegedly turned violent on Monday.
A 29-year-old woman was walking along Myuna Way when she was approached by a 37-year-old man who was holding a piece of solid timber.
The man allegedly struck the woman in the side of the head with the piece of timber shortly before 7am.
A 40-year-old man ran over to assist the woman and then got involved in a physical fight with the 37-year-old man.
The 37-year-old man pulled a large knife out of his pants and allegedly stabbed the man above his collarbone, before entering the unit block and allegedly stabbing the man a second time through a glass door.
Police attended and established a crime scene.
The 40-year-old man and 29-year-old woman were taken to Wollongong Hospital for treatment by NSW Ambulance paramedics.
The man had lacerations to his forehead and collarbone and required surgery, while the 29-year-old woman sustained injuries to the back of her head.
Forensic police spent several hours in the street and nearby apartments on Monday morning combing the area for evidence.
The 37-year-old man left a unit on Myuna Way and was arrested about 11.30am.
The man was taken to Wollongong Police Station and was later charged with affray, malicious damage, common assault and resisting police.
He was refused bail and is due to face Wollongong Local Court on Tuesday.
It is believed the man was known to the two victims.
Police inquiries are continuing.
