Queensland's club and pub operators are furious the state's contentious new lockout laws give casinos more freedom to continue serving patrons.

Our Nightlife Queensland secretary Nick Braban said companies that run casinos were well-placed to lobby political parties because of the state's revenue problem.

He said smaller venues would struggle with the changes.
