WELFARE cheats, tax rorters and crooked public servants are ripping off more than $600 million a year from taxpayers.

More than 800,000 incidents of fraud were recorded by Centrelink, Customs and other government agencies in an audit by the Australian Institute of Criminology.
With thousands of families struggling, the cost of welfare fraud rose by 10 per cent to $489 million. And hundreds of public servants were investigated for misusing credit cards, stealing equipment and illegally passing on confidential information.

Young people ripping off the dole and single mothers on parental payments have emerged as the biggest - and costliest - groups of fraudsters.
As the Gillard Government prepares to unveil a harsh Budget in May, the Institute says just $139 million - or 23 per cent - of the stolen money was recovered. After months of negotiations, News Limited has gained exclusive access to the Institute's landmark report, Fraud against the Commonwealth.
The audit shows "reported" fraud against the Commonwealth reached $589 million in 2008/09.
Its authors say fraud is being underestimated, suggesting the real cost to taxpayers is likely to be much higher.
Just more than 700,000 incidents of social security fraud were reported in the audit of 2008/09 - the height of the global financial meltdown. Other agencies also were kept busy fighting the national crime wave. Just more than 15,000 cases were reported involving international students and other foreigners fraudulently claiming visas and citizenship entitlements.

Millions of dollars also were lost on the wharves and through airports as criminal syndicates tried to avoid paying Customs duty on tobacco and alcohol. While the Institute of Criminology is cautious in assessing fraud trends, it says the findings of its 2008/09 audit are "consistent" with other reports showing a rise in crimes against the Commonwealth.
Minister for Home Affairs and Justice Brendan O'Connor said the Government was determined to crack down on the "significant amount of money" being defrauded.
"We have increased the numbers of people dedicated to fraud across agencies by more than one-third in the last 12 months," Mr O'Connor said.
In 2006/07, the loss from fraud was calculated by Government agencies to be just $34 million, but this has leap-frogged to nearly $600 million as the level of reporting becomes more robust.Crooked public servants have emerged as a big problem with $1.85 million in "internal" fraud reported in the 2008/09 audit.
The misuse of credit cards by senior bureaucrats jumped 10 per cent to 163 incidents, involving 18 separate Commonwealth agencies.
An even bigger area of fraud involved public servants obtaining and using personal information without authorisation with 1481 incidents reported.

The rise of professional fraudsters has forced federal authorities to boost resources. The Commonwealth Director of Public Prosecutions also convicted 4089 people - sending a strong deterrent to criminal elements.
The Government also has brought together key crime-fighting agencies - including the Australian Crime Commission and Australian Federal Police - with agencies such as Centrelink and the Tax Office to better tackle fraud. "We're determined to fight fraud against the Commonwealth by minimising chances for it to occur, and rapidly detecting, investigating and prosecuting fraudsters," Mr O'Connor said.
