A man has been shot dead by police on the Gold Coast - the second fatal police shooting in Queensland in as many days.

Police said the man, believed to be in his 30s, was armed with a knife and lunged at officers.

He suffered a cardiac arrest and despite efforts by paramedics to save him he died at the scene.

The shooting followed a disturbance in Nakina Street at Southport.

Acting Police Commissioner Steve Hollands was at the scene by 9:00pm (AEST) on Monday.

The Queensland Police Union said the man was a suspect in an armed robbery.

The Police Ethical Standards Command has begun an investigation that will be overviewed by the state coroner and the Crime and Corruption Commission (CCC).

There have now been six police shootings in south-east Queensland since April, four of them fatal.

On Sunday afternoon, a 51-year-old man was killed when police shot him several times in the chest at Tewantin on the Sunshine Coast.

Officers were called to Outlook Drive at Tewantin just after 2:00pm (AEST) on Sunday amid reports of a man damaging property with a steel pole.

When they arrived they were allegedly confronted by a man who got out of a car and lunged at them with either a knife or a pole.

District Officer Acting Superintendent John Bosnjak said Police Ethical Standards Command was investigating the Tewantin shooting.

'Clearly there is an issue'

Earlier on Monday, Civil Liberties Council vice-president Terry O'Gorman said the CCC or the coroner needed to do an over-arching review of all of the shootings.

"It cannot be left to guess work, it must be a subject of a serious and immediate review," Mr O'Gorman said.

"The number of shootings is a problem. It is concerning.

"Clearly there is an issue in the number of police shootings in recent times."
