A woman has been charged with murder after a man was found stabbed to death in far-north Queensland last night.

Police were called to a unit complex on Marchant Street in Manoora in Cairns after reports a man had been injured with a knife.

A 25-year-old man from Cairns was found dead at the scene about 11.50pm.

He had a serious neck injury.

A woman, 21, from Mareeba was arrested at the scene.

She has since been charged with one count of murder and is due to appear in Cairns Magistrates Court on Monday.
