The 23-year-old man allegedly attacked his 39-year-old victim about 9pm on Friday after he was asked to leave the man’s Beaconsfield home, south of Perth.
Police say he was visiting the home to speak to a woman known to him but became “violent”.
“He struck the male victim with a knife, causing a laceration injury to his throat,” a spokesman said in a statement on Sunday.
The man then fled the scene before paramedics and police arrived.
The injured man was transported to Fiona Stanley Hospital where he remains in a stable condition following surgery.
His attacker was arrested in bushland late on Saturday after detectives and the Tactical Response Group executed a search warrant at a home in the city’s northern suburbs.
The man has also been charged with other offences unrelated to the Beaconsfield attack.
These include burglary and criminal damage following an incident in Spearwood, near Fremantle, on Thursday.
He was refused police bail and is expected to appear in the Perth Magistrates’ Court on Sunday.
