Lockouts, the most contentious measure of the Palaszczuk government's bid to reduce alcohol-fueled violence, may never be introduced thanks to the effectiveness of the first stage of the laws.

The initial plan was for 1am lockouts to be introduced in a second stage of changes, but the government indicated in June the lockout may not be introduced if the first measures to curb alcohol-related incidents prove successful.

Now, with an interim report on the measures due in the next couple of weeks, Acting Premier Jackie Trad said she understands it is "a passionate issue", but the government "will not pre-empt the research data".

"The government has honoured an election commitment by introducing laws that reduce the hours where alcohol can be served after midnight," she said.
