Filming on Pirates of the Caribbean 5: Dead Men Tell No Tales, which stars Johnny Depp, gets underway this week at a set built on a secret location in the Gold Coast hinterland.
Industry sources have told the ABC that locally hired extras have been told to be on set and ready for work before dawn this week.
Screen Queensland deferred to the producers when asked to comment on the start of filming.
Production publicist Michael Singer said they were maintaining a closed set policy on the film.
"They're keeping quiet about everything going on," he said.
He said they hoped to make an official announcement later this week.
Production companies Disney and Jerry Bruckheimer have refused to confirm whether Depp has arrived in Queensland, however a photograph of the actor supposedly in Brisbane appeared on social media briefly on Monday before it was taken down.
The Federal Government spent $21.6 million to secure the production for Queensland, while the State Government offered an incentive package that included payroll tax concessions.
Queensland beat several other Australian states and Mexico to host the production.
Last year, then premier Campbell Newman said the film - the largest ever shot in Australia - would inject $100 million into the state's economy and create thousands of local jobs.
Mr Newman visited the film set during the state election campaign as the LNP pledged funding to attract more world-class film productions to Queensland.
Labor made no specific funding promises for the film industry.
Pirates of the Caribbean 5 is slated for worldwide cinema release in July 2017.
