Trading hours reforms are "farcical", will cost jobs in regional areas and result in almost no extra trading opportunities for major retailers, a peak retail association has argued.
The legislation was due to be debated in Parliament on Tuesday, after being delayed earlier this year to secure cross bench support.
Independent MP Rob Pyne plans to support the bill, the two Katter's Australian Party MPs will not, and it is understood independent MP Billy Gordon is yet to decide on how to vote on the legislation.
The changes would allow Queensland hardware stores to open from 6am on Sundays, supermarkets to open longer and butchers to open whenever they wanted.
However, there are planned amendments to the original legislation, which would create a five-year moratorium on applications for changes to trading restrictions.
Shopping centres in regional areas would also open at 8am instead of 7am, under another proposed amendment.
National Retail Association chief executive Dominque Lamb said the Queensland government had watered down the recommendations of the Mickel review and said no change would be better than what was now on the table.
Ms Lamb said the changes would take Queensland backwards.
"Queensland retailers have been fighting with one arm tied behind their backs as they are forced to close their doors and hand the market over to internet stores and overseas competition from the likes of Amazon," she said.
"Now their state government has tied the other arm behind their backs as well."
Ms Lamb said the current regime allowed the Queensland Industrial Relations Commission to decide on Sunday and public holiday trading for regional areas on a case-by-case basis.
But after negotiations with industry and cross benchers, major shopping centres, supermarkets and variety stores in many parts of regional Queensland would be forced to close their doors on Sundays for five years.
Industrial Relations Minister Grace Grace said the five-year moratorium would prevent a "revolving door of instability around trading hours".
"If you've got both sides that are a little unhappy you probably know the balance is right," she said.
Ms Grace denied Queensland looked like a "nanny state", following the Crown Prince of Denmark being turned away from a bar because of ID scanning.
"This trading hours [legislation] is a great step forward, there's a lot of benefits in this piece of legislation," she said.
"I think the negotiated outcome that we're about to debate in the house is a good compromise and I think it's going to take trading hours very far."
Ms Grace said she was confident the legislation would pass with the two amendments.
