NSW is "most fortunate" to have not lost another five teenagers in a single car crash after a car collided with a pole in Sydney's southwest.
Five Sydney teenagers were hospitalised on Friday morning after the car driven by an 18-year-old hit a power pole in Beverly Hills about 6am.
The crash drew comparisons to a similar incident on September 6 when five high school students were killed and an 18-year-old man was injured in a crash at Buxton, south of Sydney.
"Speed again is a causal factor," NSW Police Assistant Commissioner Brett McFadden said on Friday.
"We have a direct correlation to what happened just days ago in Buxton.
"We are most fortunate that we didn't lose another five lives."
Two girls, aged 16, were treated by paramedics and taken to St George Hospital in a stable condition.
Two boys, 15 and 16, were also treated by paramedics and taken to Liverpool Hospital in a stable condition.
The 18-year-old male driver had minor injuries and was taken to Liverpool Hospital for mandatory testing.
The crash came hours before one of the victims of the Buxton tragedy - Lily Van De Putte, 14 - was buried by friends and family in the town of Tahmoor.
That farewell came a day after the funeral of fellow crash victim Tyrese Bechard, 15, in Picton.
The pair died with school friends Summer Williams, 14, Gabrielle McLennan, 15, and Antonio Desisto, 16, when the ute they were in flipped and hit two trees on the evening of September 6.
The driver of the ute - Tyrell Edwards, 18 - is in custody after facing court last week on five counts of dangerous driving occasioning death.
