Property developers will be banned from donating money to state and local government politicians from today, in the lead-up to the next state election.

Premier Annastacia Palaszczuk introduced the Local Government Electoral (Implementing Belcarra) and Other Legislation Amendment Bill on Thursday, and declared the ban would apply retrospectively - effective Thursday.

Premier Annastacia Palaszczuk has introduced a bill banning political donations from property developers.

The retrospectivity would take effect if the bill was passed by Parliament - and then parties would be required to pay back any money received from property developers within that time period.

Parties and candidates could technically still receive property developer donations in the hopes the bill did not pass the Parliament, but they would be taking a risk that they would need to pay the money back.
