Three men have appeared in Brisbane Magistrates Court charged with looting during last month's floods.

Nick Jarrod Barbeler, 25, and brother Brendan David Barbeler, 26, are accused of stealing various items including a fire extinguisher, gas bottle and chair at Pinkenba.

Lawyer for both brothers Natassja Hollows told the court that concerns were held for the safety of Brendan Barbeler, who has not been heard from since the weekend.

Magistrate Brendan Butler issued a warrant for his arrest, but it will not be acted upon until another scheduled court appearance next month. Police are trying to locate him.

His brother was granted bail and remanded to a further court appearance next month.

Another two men, Bradley James Deacon, 20, and Neil Stephen Petterson, 19, also appeared in court each charged with stealing a boat at Pinkenba.

They have also been remanded to further court appearances next month.
