Three million people have had their IDs scanned at licensed venues across Queensland since the state government's controversial laws were introduced in July.
The mandatory policy gives venues power to turn away patrons who fail to carry adequate identification in a bid to curb alcohol-fuelled violence.
"Three million people have now been scanned in licensed venues in our safe night precincts, an astonishing figure which points to the thriving nightlife across our state," Attorney General Yvette D'Ath told parliament on Tuesday.
"We're seeing venues voluntarily operate ID scanners earlier in the evening, because they know they keep out violent and drug offenders on banning orders."
The Liberal National Party opposition plans to push the mandatory scanning of IDs from 10pm to midnight if it wins the next state election.
Opposition employment spokesman Jarrod Bleijie has said the party has additional concerns about limitations on who can operate ID scanning machines, an issue they will address in future.
Ms D'Ath says 320 new liquor licenses were granted in the last 2016/17 financial year, bringing the total number of venues across the state to 8185.
