SYDNEY –
A police helicopter and riot squad were deployed to a suburban street in Sydney’s south after an estimated 500 teenagers gatecrashed a 16th-birthday party in Kirrawee on Friday night, March 6, 2026, leading to three arrests and the use of pepper spray, according to police and local media. (9News)
The gathering on Bounty Avenue began as a private “Sweet 16” but escalated rapidly, with officers first called at about 7:15 p.m. local time. Police said they moved to disperse the crowd and requested reinforcements as the situation turned hostile. It took more than an hour for public order, riot squad and air support units to restore order. (9News)
Police response and arrests
Police claimed they were forced to use pepper spray after some partygoers allegedly threw bottles at them, turning what had been a backyard celebration into a public-order operation spread across several properties and the street. Officers arrested three 16-year-old boys during the operation; all were later released without charge while inquiries continue. Authorities reported no injuries, but said officers would review body‑worn video and helicopter footage as part of the investigation. (9News)
Footage sourced by 9News reportedly shows officers crash‑tackling one teen to the ground. Other clips show large groups of young people running from officers as they try to clear the area, with police vehicles and flashing lights visible across the cul‑de‑sac. (9News)
“During the arrest, police will further allege that the boy resisted officers,” the New South Wales police said in a statement in response to the incident.
“He was taken to Sutherland Police Station and was later released into the custody of a responsible adult.
“It is anticipated that the matter will be dealt with under the Young Offenders Act.”
NSW Police said they were launching an investigation into the disturbance, including the conduct of individuals in the crowd and any alleged damage to nearby properties, and appealed to locals to share their witness accounts and footage. Anyone with information has been urged to contact Crime Stoppers on 1800 333 000, with investigators seeking CCTV, doorbell and dashcam vision from around Bounty Avenue and adjoining streets.

Witness accounts and social media
Residents described scenes more akin to a street festival than a family birthday. “There were a few people climbing over their neighbours’ fence here to get in and out of the party,” local man Aedan Byrne told 9News. A helicopter was deployed to help disperse the crowds, its spotlight sweeping over nearby homes as officers directed groups away from the immediate area. (9News)
Another video posted to Facebook, captioned “Parents: do you know where your high school‑aged children are?”, showed a circling helicopter beaming a spotlight over the suburban streets, underscoring how quickly the incident became a matter of public safety rather than a private dispute.
One local Facebook user, Lisa Woods, posted that the incident brought “exciting times in the Shire”.
“Apparently the gatecrashers busted in and threw dad in the pool,” she wrote.
“They refused to leave the area, heaps more cops rocked up, and the crowds started leaving (possibly towards Cronulla), kicking some fences in along the way.”
How NSW treats juvenile offending
NSW Police said they anticipate dealing with at least part of the matter under the state’s Young Offenders Act. That law, in force since 1998, encourages diversion for eligible children through warnings, formal cautions and youth justice conferences, at police discretion and subject to the seriousness of the alleged offence.
The scheme is designed to keep suitable matters out of the courts and the adult criminal justice system, recognising that most young people who come into contact with police do so over low‑level offending. Specialist youth officers can assess whether a caution or conference is appropriate in consultation with victims and families. Outcomes can include apologies, restitution agreements, community‑based commitments or other corrective plans agreed by those involved, rather than a criminal conviction that can follow a teenager into adult life.
In practice, that means incidents like the Kirrawee party – which may involve a large number of young people, minor property damage and relatively few clear‑cut charges – often test how police apply diversionary tools while still reassuring residents that disorderly behaviour is taken seriously.
Recurring pattern of viral “open invite” parties
Friday’s disturbance fits a recurring pattern in Australian suburbs: private gatherings that swell after details spread on social media or through mass messages, sometimes requiring specialist police resources including the PolAir helicopter. NSW Police routinely advise residents who host large gatherings to use its “Party Safety” guidance and pre‑register events with local commands so officers can discuss security, alcohol management and notification of neighbours in advance.
Comparable responses have been seen elsewhere in NSW, including the use of PolAir to help disperse a house party in the Newcastle suburb of Merewether in 2024, underscoring how rapidly crowds of teenagers can overwhelm local patrols when events move from backyards onto residential streets.
Community safety planners say the Kirrawee party will likely join a growing list of case studies informing local policing strategies around youth gatherings, online “open invite” culture and the threshold at which routine calls for noise complaints are escalated to public‑order deployments.
Timeline of the Kirrawee operation
- 7:15 p.m., Friday, March 6: Police called to Bounty Avenue, Kirrawee, following reports of a large, unruly crowd at a 16th‑birthday party.
- Shortly after arrival: Officers request reinforcements, including public order and riot squad officers and the PolAir helicopter, as bottles are allegedly thrown and the crowd spills onto the street.
- Over more than one hour: Police deploy capsicum spray, gradually disperse the crowd and make three arrests of 16‑year‑old boys, all later released without charge.
- After the operation: No injuries reported; an investigation is launched and an appeal issued for CCTV, dashcam and witness accounts from residents.
Police confirmed on Sunday, March 8, that there were still no reports of injuries and that inquiries were continuing, with community submissions and digital footage viewed as central to reconstructing how the Kirrawee birthday party escalated into a helicopter‑supported police operation.
