Crooked cabbies booted to the kerb for repeat offences

Dodgy taxi drivers who repeatedly overcharge passengers, refuse short trips or do not use the meter will face 10-year bans under an industry crackdown.

About 100 drivers in NSW have been hit with multiple fines in the past two years, while more than 2500 overcharged passengers have received refunds.

Other examples of bad taxi driver behaviours include trying to negotiate a fare that is not displayed on the meter, adding an extra surcharge or pinging passengers with a maxi-taxi tariff when fewer than five people are in the van.

But some drivers sacked from one cab company have appeared behind the wheel of another taxi company, or jumped over to Uber.

Those law-breaking drivers have been warned they will no longer only face fines, with repeat offenders to be hauled before a court from December 6.

Any driver twice convicted in court will be handed a 10-year industry ban.

A database would help monitor offences by rogue drivers, NSW Transport Minister Jo Haylen said.

"This will result in rogue drivers being kicked out of the industry, whether they drive for taxis, Uber or other ride-share operators," she told reporters on Wednesday.

The taxi and rideshare watchdog has encouraged passengers to report overcharging and other incidents to the taxi fare hotline.

Even when a fine or refund could not be issued, each report helped inform where targeted covert stings were needed, Point to Point Transport Commissioner Anthony Wing said.

"My investigators ... look for people who are getting multiple reports and follow those up to potentially prosecute them," he said.

More than 900 fines have been issued in the past two years.

NSW has more than 15,000 taxi drivers across 266 companies.

Peak industry body the NSW Taxi Council welcomed the change, which it said came in response to its calls to weed out bad drivers.

"We want to send a strong message to the majority of tax drivers providing a good service - we have their back and we want to ensure we have a thriving industry," chief executive Nick Abrahim told AAP.

"The few who are tarnishing the industry are who we want to weed out."

He called for further measures to reduce meter tampering and centralise accreditation.
