SYDNEY (Reuters) - An Australian court has issued a blunt warning about the sexual predators a young driver faces in jail if he does not stop speeding, as authorities struggle to stop teenagers street racing.

"You'll find big, ugly, hairy strong men (in jail) who've got faces only a mother could love that will pay a lot of attention to you -- and your anatomy," said Magistrate Brian Maloney.

The 19-year-old male appeared in Sydney's Downing Center Court on Monday charged with driving without a license, failing to stop at a police alcohol check point and driving dangerously.

It was his third time before the courts for driving offences, prompting the magistrate's warning he would be jailed next time.

Maloney barred the teenager from driving until 2013, placed him on a 12-month good behavior bond and ordered him to do 150 hours of community work.

Breaching any of these conditions would see the teenager jailed where he would "shower with the gorillas in the mist down at Long Bay jail," said Maloney, his comments confirmed by the court on Tuesday.
