An Indigenous woman has died while in the custody of Queensland police.

The 49-year-old woman was found dead in her cell at the Brisbane City Watch House early on Thursday.

Police said the woman, who was charged over drug and property matters on Sunday, appeared in Brisbane Magistrates Court on Monday.

She had been remanded in custody until 7 October and was due to be transferred to a prison.

The cause of the woman's death is being investigated by Ethical Standards Command under supervision by the Coroner and Queensland's Corruption and Crime Commission.

In a statement, police said they had not ruled out underlying health conditions.
