Reports out of India suggest Adani is struggling to raise the final $2 billion for the $16.5 billion project, with local banks there reluctant to increase the company's already high debt.
Adani insists its Carmichael mine is ready to go and it isn't worried about securing the funding.
Despite previously pushing the project as a valuable jobs generator, the premier on Tuesday said her government would not consider giving any loans to Adani to get the project over the line.
"My government has always said that it is a matter for Adani to get the finance. This is a private investment." Ms Palaszczuk said.
"But I haven't heard any reports from Adani themselves that they've indicated anything to the contrary."
Environmental activists claim 21 banks have so far ruled out lending money to the project, including Deutsche and HSBC.
Three of Australia's Big Four banks have also ruled out lending the company money.
In addition to its reported debt problem, Adani is also facing concerns in India about its Mundra thermal power station in Gujarat state.
The plant would take coal from the Carmichael mine, but the facility has become unviable due to increasing running costs, and the company is trying to offload it to local authorities.
Adani is also trying to secure a $1 billion loan from the federal government's Northern Australia Infrastructure Facility to build the rail line linking the mine with the Abbott Point coal terminal.
