Christmas Day is going to be a tense one for the family of a jet-skier missing near Sydney, as a search for the man resumes.

Emergency services were called to Burraneer Bay on the Hacking River in southern Sydney about 7.30pm on Friday, after receiving reports three men had been thrown from the jet ski.

The driver and one passenger, who were wearing life jackets, were rescued but the third man could not be located.

Police, surf lifesavers and paramedics searched for the man, believed to be in his 30s, for about an hour, before pausing their efforts due to poor light.

The search resumed on Saturday morning, with police divers joining the team scouring the water for the man.

The 44-year-old driver of the jet ski remains in St George Hospital with suspected chest injuries but his 39-year-old passenger was not injured.
