Police are investigating after a man sustained critical injuries from an alleged assault at Southport this morning.
Preliminary information indicates three people returned to their vehicle on Barney Street after fishing in a nearby waterway around 12.10am.
As they put items back in the vehicle a verbal altercation occurred between a 33-year-old man from the group and a 45-year-old male resident from a nearby unit complex.
The resident then came outside and the altercation allegedly continued on the driveway.
The 33-year-old man then allegedly punched the resident once in the face, causing him to fall backwards, hit his head on a skip bin and then on the concrete.
The group called emergency services and police attended the scene. The 45-year-old man was transported to Gold Coast University Hospital in a critical condition.
A 33-year-old man has been charged with one count of grievous bodily harm. He is expected to appear in Southport Magistrates Court on October 19.
