Vic court told of stabbing confession

A man confessed to his friend about stabbing a stranger outside a Melbourne train station, a court has been told.

Cody Frost has pleaded not guilty to the murder of 24-year-old Marcus Rowley in West Footscray on August 5, 2017, arguing self-defence.

Crown prosecutor Mark Gibson SC told the Victorian Supreme Court on Wednesday that Bethany Micallef gave a statement to police a day after Mr Rowley's death, informing them of Frost's confession to her.

Ms Micallef was with Frost as they got off a train at Tottenham station at 6.42pm.

An intoxicated Mr Rowley, who also disembarked the same train, approached them for a cigarette.

The friends and the victim went their separate ways, but Mr Rowley and Frost crossed paths again a short time after as Ms Micallef crossed the road.

The court was told Frost had called out "get away" to Mr Rowley, as Ms Micallef walked away faster.

At one point she turned and saw Frost facing Mr Rowley with his arm raised.

However, Micallef didn't realise what had happened until seeing news of Mr Rowley's death the next day.

The court was told Ms Micallef confronted Frost about the incident and he admitted stabbing Mr Rowley.

She gave a statement to police on August 6 about what she had been told, and a few hours later Frost went to Footscray police station, where a knife and clothing were seized.

Mr Gibson told the court Frost's actions were conscious, deliberate and voluntary.

Defence lawyer Ashley Halphen told the court Frost's intentions were not to kill or cause serious injury and he was acting in self-defence.

Mr Halphen said he would let the evidence speak for itself.

The trial before Justice James Elliott continues.
