Despite constantly pushing the 'one punch can kill' message, it seems the reality is not getting through.
And even when the attacks don't end lives, they can certainly change them forever.
Chris Wallace's life wasn't lost but it was ruined by a senseless act of street violence. He is just starting to say his first words after being king hit four months ago.More stories from Today Tonight
Before the unprovoked attack 31-year-old Wallace was a normal young man. Now he's so weak he can't life a light plastic ring.
His left side is totally paralysed and he is destined for a life in a wheelchair.
The frightening and ugly cause of massive head injuries like Wallace's can be seen in our cities and towns every weekend as streets turn into virtual battlegrounds.
Punches are thrown without a thought and wild brawls fuelled by alcohol and drugs are sparked by incandescent rage.
If you're caught in the middle of it, there's every chance you'll be seriously hurt and even killed.
49-year-old grandmother Sharon Cameron is living proof that senseless violence does not discriminate against age or sex. She was punched in the face in an unprovoked attack during a night out with friends.
"I ended up with multiple fractures to my nose, and I just had blood streaming through my hands," Cameron said.
She could easily have become another fight-night statistic, but luckily wasn't.
Wallace's parents are now forming a nationwide network of families and parents to force Governments to get tough on alcohol-fuelled violent crime.
They want every state to introduce new legislation to crush the king hit, so when other young Australian men and women go out, they don't come home brain-injured like their son, or even worse.
