Mandatory sentencing must be dropped from Queensland's anti-gang laws because it encourages people to lie or make false accusations to avoid jail, says a civil liberties body.
The Palaszczuk government's revised anti-gang laws will come under scrutiny on Wednesday when they are debated by a parliamentary committee.
Queensland Civil Liberties Council vice president Terry O'Gorman says a person can avoid mandatory sentencing by helping police, but that alone creates bigger issues.
"If you have no information to help police, you will make it up. If they do have some, they will jazz it up," Mr O'Gorman told AAP.
The Labor government last month introduced its anti-bikie laws in a bid to wind back the contentious legislation of the previous LNP government.
Under Labor's version, mandatory sentencing will be reduced from 15 to 25 years to a maximum of seven.
It will have to rely on the support of crossbenchers to pass the reforms, which also target organised crime involving dangerous drugs, child exploitation and sophisticated fraud.
Under the changes, the maximum jail term for child exploitation offences would be increased from 14 to 20 years, and the maximum sentence for dangerous drug trafficking would rise from 20 to 25 years.
The anti-bikie reforms include a new consorting offence similar to that in NSW and will allow police to confiscate furniture, including stripper poles, from restricted premises.
Mr O'Gorman said the laws meant a person could serve seven years even though they may not receive a custodial sentence for the offence they had been charged with.
He said mandatory sentencing must be removed from the anti-gang legislation.
