A Queensland Police spokeswoman confirmed the men, both aged 21, had been charged with one count each of causing grievous bodily harm.

The men, one from Coombabah and one from Tanah Merah, are expected to face Brisbane Magistrate's Court on Monday morning.
Earlier on Sunday a team of detectives was scouring CCTV footage in a bid to identify up to four men they believed to be responsible for the attack.
Police believe the 18-year-old man, from Highgate Hill, was walking towards Ann Street with a friend in the Chinatown Mall about 3.35am on Sunday when they were approached by the men.
At a press conference earlier on Sunday, Detective Acting Inspector Tom Armitt said one of the assailants punched the teenager in what he described as a "random act of violence".
"A short exchange has occurred and the victim was struck to the back of the head, has fallen forward and is currently in his present condition," he said.
The young man's condition was listed as critical in the Royal Brisbane and Women's Hospital.
Police were confident there were no links between the attack and another incident at the nearby TBC club on Brunswick Street, an hour earlier at 2.35am, in which a 24-year-old Beenleigh man was attacked as he sat in a chair.
Acting Superintendent Peter Aitken said that man was struck across the face with a ceramic mug, but suffered only minor injuries.
Anyone with information about either assault should contact Crime Stoppers on 1800 333 000.
