A 24-year-old woman has been charged with the murder of her 26-year-old boyfriend, Delroy Francis Bin-Garape, who died on a Brisbane footpath from "catastrophic" injuries caused by a stab wound to the chest.

Paramedics were called to the scene by the woman just before midnight.

They worked on Mr Bin-Garape for about 30 minutes, but he was pronounced dead at the scene.

Police said he had been stabbed with a large knife.

"The injuries that the deceased suffered last night were obviously catastrophic and resulted in this man's death," Detective Inspector Mark Thompson said.

Police took 24-year-old Liddel Ramsey into custody overnight and she was charged with murder on Wednesday afternoon.

It is understood Ms Ramsey will claim she was defending herself at the time.

Police said the pair lived together in a unit near where the man died and were seen coming and going from their residence, together and separately, throughout the night.

Detective Inspector Thompson said police wanted to hear from anyone who may have seen the two yesterday.

"Anyone that has any CCTV footage around the Junction Terrace Annerley area and the Ipswich Road Annerley area, we are particularly interested in the time period between 6:00pm and midnight on yesterday's date," he said.

Detective Inspector Thompson said the victim's family was "distraught".

"No-one would like to hear this news and police are working with them to make sure they are supported throughout this terrible time in their life," he said.

A crime scene has been declared and specialist officers worked on scene into the afternoon.

Ms Ramsey did not appear during a brief mention in the Brisbane Magistrates Court and will remain behind bars until the matter is heard again on July 15.
