High-profile lawyer Adam Magill among four charged with fraud and money laundering offences

High-profile lawyer Adam Magill is among four men charged with fraud and money laundering offences following an 18-month investigation into his Queensland law firm.

The Brisbane men were arrested after Crime and Corruption Commission investigators allegedly uncovered fraud against Legal Aid Queensland valued about $340,000.

A failure to comply with a legal requirement to deposit more than $765,000 into a trust account was also allegedly discovered.

The CCC will also allege some of the men laundered the proceeds of serious criminal offences.

Mr Magill, 47, was arrested at his Tarragindi home this morning and charged with two counts of aggravated fraud, fraudulent falsification of records and aggravated money laundering.

He was remanded in custody and is expected to appear in Brisbane Magistrates Court tomorrow.

Mitch Cunningham and Corey Cullen - criminal lawyers who worked at Mr Magill's firm - were also arrested and charged with aggravated fraud. 

Both men were bailed to appear in Brisbane Magistrates Court on November 19.

A 30-year-old Inala man was also charged with aggravated fraud and aggravated money laundering.

The man was also remanded in custody and is expected to appear in Pine Rivers Magistrates Court tomorrow.

CCC Chairman Alan MacSporran QC said any fraud committed on Legal Aid Queensland was fraud against the state's taxpayers and had the potential to interfere with the administration of justice.

"The fact some of these allegations relate to individuals involved in the legal profession is (also) concerning," he said in a statement today.

More arrests are expected in the coming days.

The probe into the legal fraternity has seen several high-profile lawyers fall from grace.

Tim Meehan, who defended Daniel Morcombe's killer Brett Peter Cowan, was last year sentenced to five years in jail for fraud.
