CCTV captured the moment Billy Dean Fallon came out of a toilet cubicle and began punching the cleaner on January 20 at a nightclub in Burleigh Heads on the Gold Coast.
The cleaner had been knocking on the door for several minutes before Fallon charged out and launched into the attack.
Multiple people were seen attempting to separate the pair.
The victim was left with a broken nose and head injuries.
The court heard Fallon was getting “intimate with his partner” in the toilet stall and he thought the people outside were wanting to attack them.
