At least two Queensland mayors will be automatically suspended when local government reforms passed by state parliament become law.
Logan Mayor Luke Smith, who is fighting corruption and perjury charges, and Andrew Antoniolli, who stood aside as Ipswich mayor following fraud charges, are among five councillors who will soon be stood down.
Local Government Minister Stirling Hinchliffe has told parliament they will be suspended while they deal with charges levelled against them.
Legislation passed by the Labor government on Thursday grant Mr Hinchliffe the power to sack or suspend elected council officials charged with corruption or integrity offences.
The reforms are expected to become law next week.
Measures include an obligation on councillors to report another councillor's conflict of interest or material personal interest when they believe it has not been declared, and a ban on political donations from property developers.
Also, a new code of conduct for councillors will bring them into line with MPs and government staffers, and a councillor conduct tribunal will be set up to hear and determine alleged misconduct.
The moves follow an ongoing Corruption and Crime Commission investigation of council officials that is expected to result in more charges.
