Salim Mehajer is mocked in jail for being 'high maintenance' by other inmates, a fellow prisoner has claimed.

A note reading 'princess' was allegedly placed above his cell door along with a picture of a tiara.

The former Auburn deputy mayor is behind bars in Silverwater Correctional Centre, New South Wales, accused of staging a car crash to avoid a court hearing in October.

'It could be just a joke, but in my experience being called high-maintenance is a sure sign of disrespect,' a former Silverwater inmate told the Sydney Morning Herald.

'From my perspective, because he is well-known, someone might be trying to get under his skin and find a weakness in him.'

He added: 'There are a lot of dangerous people in there so you need to be mindful not to disrespect anyone.'

Mehajer's former cell mate last month claimed the businessman walked around 'half-naked' with just a towel on, refused to clean the cell toilet, and gave him a back rub.

It comes after the disgraced property tycoon was convicted of assaulting a taxi driver outside The Star casino in Sydney.

Mehajer, 31, on Monday pleaded guilty to assault occasioning actual bodily harm and destroying property over the April attack.

He was on Thursday convicted and sentenced to a three-year good behaviour bond and instructed to seek anger management counselling.

Mehajer was charged after he threw an eftpos machine at a taxi driver's face and stole his iPhone outside the casino at Pyrmont.

Last week the property developer was found guilty of assaulting Seven Network reporter Laura Banks when he slammed a car door on her arm as he tried to leave a police station.

In the incident outside the casino on April 2 last year, he yelled: 'I go crazy in seconds. I am getting angry you f***ing dog' before he smashed the driver's face with an EFTPOS machine, the court heard.

The court heard Mehajer was leaving Sydney's Star Casino at 4.30am with work friends when he began chatting to a group of four women.

He told one of them 'I wasn't talking to you. I wouldn't talk to you if you were the last female on earth,' according to court documents.

One of her friends took offence and started arguing with Mehajer while another friend filmed it on her iPhone.

The court was told Mehajer in a fit of rage smashed her iPhone on the floor before jumping into a taxi with his friends, throwing $200 at the driver and shouting 'just drive'.

But then he changed his mind, ordered the taxi back to the casino before getting out, opening the passenger door and demanding some of his money back.

The court heard Mehajer had traded insults with Ms Banks, who teased him about his height, after he asked if the jewellery she was wearing was a ring or a key ring

As he and the driver argued, Mehajer grabbed the EFTPOS machine and the driver's phone and told him: 'If you give me $50 back, you will get back these items.'

He then battered him with the machine leaving him with a bloody nose, the court heard.

Mehajer pleaded guilty in a deal which saw prosecutors drop a charge of larceny.

In sentencing for his attack against the journalist, Magistrate Joanne Keogh criticised the behaviour of a media pack at the police station but still ordered a conviction with penalty to be recorded against Mehajer.

Ms Keogh also criticised evidence given by Ms Banks calling her 'a witness of little credit' and 'not a witness that has stood up to the scrutiny of cross-examination'.

The incident took place outside Day Street police station on April 2 last year, where Mehajer had been taken early that morning after assaulting the taxi driver.

The court heard Mehajer had traded insults with Ms Banks, who teased him about his height, after he asked if the jewellery she was wearing was a ring or a key ring.

Mehajer said he felt 'cornered, bullied and harassed' by a media pack moments before he slammed the door on Ms Banks.

'It all happened very quickly and my only thought was to leave,' Mehajer said in court of the door slamming.

'As selfish as this may sound I wasn't aware of the extent of the impact.'

Ms Banks had been standing in the doorway of the Porsche trying to quiz Mehajer on the incident when the assault occurred.

The court heard the pair had been trading verbal barbs before the incident, with Ms Banks asking the disgraced property developer if he had hit 'rock bottom'.

Ms Banks, a former newspaper turned TV reporter, claimed her back was 'still quite sore' almost 12 months on from the incident.

She denied deliberately provoking Mehajer during their confrontation prior to the alleged assault.

The 31-year-old journalist even suggested Mehajer had been flirting with her when he asked: 'Why are you attached to me?'

'It was almost suggestive, flirtatious,' Ms Banks told the court.

'He was suggestive in some of his comments. Asking me to get in the back of his car felt like that was suggestive and had innuendo behind it.'
