Two Melbourne women have avoided a jail term for their vicious attack on a bus driver last year.

On November 29 last year, Tahlya Evans, 40, and 22-year-old daughter Courtney were caught on CCTV assaulting a Dandenong bus driver after he asked them to pay their fare.

They became verbally abusive, and punched, scratched and bit Faavae Tuiloma before spitting at him as they fled the bus stop at Dandenong Plaza.

The 44-year-old told 9NEWS at the time he had "a high respect for the females and I was injured, but in my heart I am glad I let them go".

"I pushed this big lady ... and I feel my thumb went straight in her mouth and she bit it," he said.

Mr Tuiloma took one day off work before returning to the job he has held for five years.

Today, magistrate Jack Vandersteen told the court "the bus driver showed a great deal of restraint ... it was in his workplace, he's entitled to feel safe".

The two women from Noble Park were charged with assault and intentionally causing injury, Tahlya also charged for punching a female passenger on the bus who had asked the women to stop yelling abuse.

"The escalation of your behaviour in these offences just can't be accepted," Magistrate Vandersteen said.

The court heard details of the women's lives. Both women suffer from a mental illness and have been the victims of family violence.

Tahlya Evans was diagnosed with schizophrenia, ADHD and a borderline personality disorder, while her daughter experiences symptoms of post-traumatic stress disorder.

The magistrate said he took into consideration the women's guilty pleas, a display of remorse and their significant mental health issues, and noted Courtney is her mother's primary carer.

"If you don't feel it's going your way, it's better to do what you've done today, close your mouths and walk away," he said.
