Queensland Premier Annastacia Palaszczuk has compared the state's entertainment precincts to "war zones" as she continues her pleas to the cross bench to support the government's lock out legislation.

On the eve of the beginning of the debate, Labor-turned-independent MP Billy Gordon said he was "unmoved" by the government's case. Robbie Katter and Shane Knuth have also said they were "not convinced".

Labor needs at least one of their votes to pass the laws, which would see a 3am last drinks call with a 1am lock out in entertainment precincts, and 2am last drinks in all other areas. Shots will also be banned after midnight, with the government still working out how to treat whisky bars. The state's casinos will be exempt.
