Political donations and campaign spending would be capped in Queensland under a state government bid to make elections fairer.

"Big donations are gone, they will be no more," Premier Annastacia Palaszczuk announced on Tuesday.

"We want to push back on attempts to buy elections."

Laws to limit political donations and expenditure will be introduced to Parliament next month and debated in February, with spending caps to take effect in time for next year's state election.
