Two people have been charged after shots were fired at the advertised venue of a wake for slain Sydney crime boss Lorenzo Lemalu.

Police allege a 17-year-old boy fired 30 rounds at the venue in Sydney's south-west.

Police say a 17-year-old boy fired 30 rounds at the advertised venue of a wake for slain Sydney crime boss Lorenzo Lemalu at the weekend.

The 17-year-old is one of two people charged over the shooting at the venue in Sydney's south-west.

Police on Saturday afternoon responded to reports shots had been fired at a Punchbowl venue, with video shared on social media appearing to show gunmen shooting from inside a car at the property.

The venue had been advertised as the location of Lemalu's funeral, but plans changed and the memorial was held at Lakemba Mosque on Sunday.

Police believe Lemalu was the head of the so-called "Coconut Cartel", a gang involved in tit-for-tat shootings with the Alameddine crime family and whose name comes from a historic slur against Pasifika people.

Lemalu was shot dead in Ho Chi Minh City in Vietnam on May 21 in an attack that two Samoan men have since confessed on Vietnamese TV to committing.

Police were also called to nearby Gillian Place in Punchbowl after reports of a fire on Saturday and found an abandoned car alight.
