Disgraced former Auburn deputy mayor Salim Mehajer's prolonged application to lift bail restrictions will "go down in the record books", according to a frustrated judge.

Mehajer, 32, was released from Cooma Correctional Centre last month after spending nearly a year behind bars for electoral fraud.

The day after his release, he launched a District Court application to vary bail conditions, including lifting restrictions that prevented him from using a phone and social media.

Mehajer also wanted a curfew removed and a less frequent regime of reporting to police.

The matter has been listed for five days and been dragged out over a three-week period by delays with evidence, requests to call witnesses and new arguments being raised.

"This is going to go down in the record books I think, this application to vary bail," Judge James Bennett said today.

"The longest running such matter in the court's history."

Over the past three weeks, his lawyers have argued he requires Instagram to stay in touch with family and promote a domestic violence charity.

"In today's day and age it is imperative that communication is instant," his sister Mary told the court last month after being called to give evidence.

But the court also heard he has used the platform inappropriately in the past.

Mehajer's barrister Dymphna Hawkins said she would call an expert to give evidence about why Mehajer's Lidcombe home has never had a landline installed.

As part of arguing for the phone restrictions to be lifted, Mehajer's legal team has cited difficulty getting in touch with him when he has no phone.

He has also told the court his safety was "paramount" and he is worried how he might seek help if he is followed by a media pack.

When asked whether he was aware of the consequences of breaching bail under oath late last month, Mehajer replied: "I'm totally and utterly aware of the consequences and I can assure you I won't breach them."

One week later, he was arrested for breaching bail conditions which prohibited him from contacting a witness in one of the cases against him.

Mehajer then won his freedom back after claiming he had failed to read the conditions properly before signing them.
