The mother and daughter accused of biting and spitting on a Melbourne bus driver claim he attacked them first.

The Noble Park women, aged 40 and 22, turned themselves into Dandenong police station at about 1.30pm today, after CCTV vision of the incident went viral.

"He did it first on my side of the head and I have photos to prove it," one of the women told 9NEWS.

The pair were captured on camera allegedly punching, slapping and spitting on the 44-year-old driver after he asked them to pay their fares.

The alleged attack took place on November 29 after the pair boarded at Dandenong Plaza Shopping Centre and disembarked at nearby Dandenong Station.

Police allege the pair turned on bus driver Faavae Tuiloma when he asked them to pay their fares.

"I have a high respect for the females and I was injured but in my heart I am glad I let them go," he said.

Mr Tuiloma grappled with both women after they allegedly attacked him, tearing his shirt and spitting on him before leaving the bus.

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

Senior Constable Charith Pathirana commended Mr Tuiloma for remaining calm while he waits for results of a blood test after his hand was bitten.

Mr Tuiloma said he "wasn't expecting ladies to do that kind of thing".

"All of a sudden (one of the women) punched me in the chest," he said.

"I have a high respect for females and I'm defending myself, I just need to get away."

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

"I try to ignore it but it's still in my mind," he said.

Mr Tuiloma said the state government was considering installing security cages on buses in "dangerous areas" but should consider installing them on all buses "for the safety of the drivers".

As for the two women accused of the attack, Mr Tuiloma said he has to forgive them.

"You have to forgive everybody ... the law is the law but I forgive them," he said.

The 22-year-old woman was charged with unlawful assault, indecent assault and wilful damage.
