Glamorous sisters who took turns slapping an ex-boyfriend they ran into during a drunken birthday party walk free from court after admitting they let their 'emotions overflow'

•  Sisters Irene, 25, and Nansia Koukounaris, 23, pleaded guilty to common assault
•  The pair slapped Irene's ex-boyfriend at a Bondi Beach bar in December 2019
•  They escaped conviction as the court deemed the pair acted 'out of character' 

Two glamorous sisters who took turns slapping an ex-boyfriend on a drunken night out have avoided a conviction. 

Irene Koukounaris, 25, and her sister Nansia Koukounaris, 23, faced court on Friday for their 'slap attack' on Michael Ensor during a birthday party at Bondi Beach Public Bar in Sydney's east last year. 

Irene, an aspiring lawyer, had dated Mr Ensor for four years but their relationship had ended. 

When they ran into each other at the bar, 'emotions overflowed', the court was told. 

Nansia, a primary school teacher, was the 'initial aggressor' who 'took up her sister's plight' after the relationship 'eroded and broke down'.

She felt responsible as she was the one who had introduced Irene, an aspiring lawyer, to Mr Ensor. 

The sisters from Randwick were the ones who approached Mr Ensor at the Bondi bar before getting into a 'heated argument' on December 21, the Southern Courier reported.  

Mr Ensor, who had lived with the sisters in their parent's house at one point in the relationship, repeatedly asked the sisters to 'back off'.

Nansia then slapped the left side of his face when he moved away. 

Irene then slapped the right side of her ex-boyfriend's face and threw a drink on him.     

The arguing continued outside the bar and security were forced to intervene before police arrived at the scene.

'Yeah I slapped him,' Nansia told police upon arrival.   

Mr Ensor reported Nansia and Irene the night after the public slapping on December 21 last year.  

The two former St Spyridon College students pleaded guilty to common assault charges and faced Waverley Court multiple times over a five month period.

The court determined the sisters were acting 'out of character' and they were given a six-month Conditional Release Order. 

Magistrate Ross Hudson said the assault was at the lower end of objective seriousness and gave the sisters a two-year apprehended violence order that required them to steer clear of Mr Ensor. 

Magistrate Hudson backed their good character and reminded the pair of the importance of 'reputation'. 

'Make sure you always remember wherever you are, whoever you're with, your respective professions require you to maintain integrity,' he said.
