A woman has been let off with just a $250 fine after she stabbed a man in the head with one of her stiletto heels in a random attack during her 21st birthday celebrations.

Jazzmin Fry used one of her shoes to attack stranger Kyle Johns, 19, in Brisbane's Fortitude Valley in the early hours of February 24.

Mr Johns' scalp had to be stapled back together after he was left lying barely conscious on the pavement in a pool of his own blood.

Fry pleaded guilty to assault and was given a $250 fine but no conviction was recorded.

Before the attack, Fry was filmed advancing towards Mr Johns, who is 1.95m tall, as he retreated.

She took off her shoe and threatened him, asking: 'Want my f**king heel through your eyeball c**t?'

Fry had worked as a property manager at real estate agency Ray White in Beenleigh before she was fired on Tuesday.

'It was a drunken act. It was my 21st birthday and it's not me. I don't know why I did that and I wasn't in the right mind frame,' she told Nine News.

Mr Johns said Fry's punishment was insufficient.

Mr Johns said he has not felt safe enough to go out with his friends in Brisbane since he was stabbed by Fry. Pictured: Mr Johns' bloody shirt after the attack

'[She] comes to the middle of China Town with her heels in her hand and stabs me in the crown of my head,' Mr Johns said.

'[I'm] devastated to be honest. If the roles were reversed would I be getting the same, pretty much a slap on the wrist?'

His mother Susan was woken up at 2.29am and told her son had been attacked, and she feared he could have died.

Fry said she has not been out drinking since the attack, but a social media post reportedly showed her with an alcoholic drink in her hand posing with friends before a music festival.

Mr Johns said he has not felt safe enough to go out with his friends in Brisbane since he was stabbed by Fry.

Ms Johns said she was 'very angry' at Fry's punishment, while her son was 'beyond angry'.

Recounting the night of the attack on her son, Ms Johns said it was 'every parent's worst nightmare'.

'I arrive panicked to the ER and the ambulance hadn't arrived. I'm then told ''he has been stabbed in the head'', now I imagine the worst and spiral - the emotions I experienced in 30 seconds can not be expressed,' Ms Johns posted to Facebook.

'Worst case scenario, he could have lost an eye, suffered an internal bleed or worse - death from head injuries.'
