A man has suffered a cut head in an unprovoked Australia Day attack on a street in Sydney's east.
Police said the 24-year-old victim was standing on the footpath on Campbell Parade at Bondi when an unknown man pushed him in the chest then punched him in the head, about 9pm (AEDT) Sunday.
The 24-year-old fell to the ground and struck his head on the pavement, police said in a statement.
He was taken to St Vincent's Hospital with a laceration on the back of his head.
The attacker fled the area with two other people in a silver 4WD.
Detectives are looking for a male who's described as Caucasian, 190cm tall, about 17 years old with short brown hair.
