A man has been shot by police after officers were called to conduct a welfare check in West Mackay.
Police attended an address on Bridge Street around 2.30pm Monday following reports a man had threatened self-harm.
Negotiators were notified to attend the scene and speak with the man.
An emergency declaration under the Public Safety Preservation Act (PSPA) was declared around 4.10pm and an exclusion zone was established on Bridge Street, Hume Street and Streeter Avenue while police continued to negotiate with the man.
Officers were confronted by a man allegedly armed with a firearm.
The 24-year-old man allegedly advanced at officers and was subsequently shot just after 5pm.
He was transported to Mackay Base Hospital in a critical condition, where he was later declared deceased.
A crime scene has been established, as an investigation by the Ethical Standards Command continues. The investigation is subject to oversight by the Crime and Corruption Commission.
