There have been angry scenes at the sentencing of an HIV positive Sydney taxi driver who raped three women.

In sentencing Hassan Nagi to at least nine-and-a-half years jail, District Court Judge James Bennett described his behaviour as predatory and a breach of his victims' trust.

The 39-year-old pleaded guilty to raping three female passengers aged 31, 23 and 27 between 2003 and 2007.

Two of the women were heavily intoxicated and on their way home at night.

The court heard Nagi is now HIV positive but that there is no proof he had HIV when he raped the women. His lawyer said he believes he contracted the virus from a dental surgery.

However the judge noted that he did not use a condom on any of his victims and that the risk of infection by a dentist was very low.

Nagi had previously admitted using prostitutes from the age of 20.

Lawyers for Nagi, who is from Bexley in Sydney's south, had argued he suffered a condition called Don Juanism, or "a man's equivalent of nymphomania" which made him addicted to sex.

But the Judge spoke of the driver's lack of respect for women.

He said his offences were serious and had an element of pre-meditation because he drove the women to out of the way places. He said Nagi abused his position of trust as a taxi driver.

Two of his victims were in court.

Hassan Nagi held up a photo of his children and yelled at the media after he was sentenced.

"I swear on my kids you are going to be shocked. Put the date down that I am going to be released. You will get a big shock," he said.

His mother yelled, "He's innocent".

Nagi was given a maximum sentence of 13 years and 10 months. He will be eligible for parole in October 2018.

Outside Downing Centre District Court Nagi's mother said, "My son is very healthy".

She had an angry exchange with a member of the public who shouted, "Would you like it if it was your daughter?"
