A serial dumper has been fined $225,000 for leaving asbestos waste in Sydney's south-west.

Dib Hanna pleaded guilty in the NSW Land and Environment Court to four offences that were caught on camera in April 2012.

He was seen dumping eight truckloads of asbestos-laced material on vacant land at Picnic Point in Sydney’s south-west.

He was ordered to pay the legal costs of Bankstown City Council, which brought on the case.

Hanna will also have to pay for a notice detailing his offences to be published in newspapers.

The contractor had already racked up fines for similar offences that will see him paying off debts for the next 60 years.

In 2011, he was found guilty of contempt of court, for failing to comply with orders about illegal dumping and was handed a suspended sentence with a good behaviour bond.

The chief justice of the NSW Land and Environment Court, Brian Preston, said although Hanna could not be punished again for other offences, there needed to a substantial increase in the penalties previously imposed.

"Mr Hanna is a persistent offender who has not been deterred in the past by the penalties and sentences imposed for prior offences," Chief Justice Preston said.

Outside court, a spokesman for Bankstown City Council welcomed the penalty, saying he hoped it would act as a deterrent to Hanna and others.
