WITH a truck full of asbestos, Dib Hanna would scour Sydney's western suburbs looking for a vacant block or deserted park to dump his deadly load.

Hanna, one of Australia's worst rubbish dumpers, was caught in an elaborate sting by authorities between July and October 2009.

He was fined $133,000 on Wednesday for dumping waste in four incidents between July and October 2009.

Among the rubbish was chrystotile asbestos - the most dangerous type of asbestos responsible for almost 90 per cent of asbestos health problems - and brown or armosite asbestos.

Justice Malcolm Craig in the Land and Environment Court said Hanna had been paid by companies to take rubbish from building sites.

Hanna's battered Mercedes tip truck would roam western Sydney searching for land on which to dump his loads.

In October last year investigators from the Department of Environment Climate Change and Water and the Western Sydney Regional Illegal Dumping Squad followed Hanna from his Colyton home as he drove 25km across western Sydney.

He was videoed tipping waste that included asbestos on to an empty building site in Rooty Hill.

A month before, Hanna had been filmed dumping waste in public parkland in Hargrave Park.

In the third incident DECCW investigators placed "unique markers" in the tipper of Hanna's truck that contained a load of waste. The waste, containing both chrystotile and armosite asbestos, was later found in Minchinbury.

The last incident saw Hanna forced to admit he had also dumped a pile of building waste at Bankstown Airport.

Some of the asbestos panels Hanna dumped were broken and splintered, making the threat more dangerous.

Justice Craig, in sentencing Hanna, described the string of dumping offences as a "deliberate course of criminal behaviour", and fined him $104,000 while ordering him to pay $8000 in clean-up costs and $21,000 in legal fees.

In September last year Hanna was convicted and fined $26,000, as well as $14,000 in clean-up costs, for dumping waste in December 2008 and February and March 2009.
