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.
It means the donation ban would effectively be in force for the upcoming election campaign if it was held before the bill passed,which was possible as the Legal Affairs and Community Safety Committee was asked to report back by November 27.
It has been suggested the election date could be November 18,or it could also be next year. The election must be held by May 2018.
The last sitting of Parliament for the year is November 28 to 30,so the bill could be brought on for debate then.
Ms Palaszczuk has previously indicated she wanted the bill togo through the committee process,which meant it would not be rushed through this sitting week.
Labor stopped taking donations from property developers on Friday.
