A young man was the target of yet another racist rant on a Sydney bus.

FOOTAGE has emerged of yet another racial attack on a Sydney bus - but this time, the victim is a school boy.

Video posted to YouTube and aired on A Current Affair last night shows a 50-year-old woman hurling verbal profanities at a young male of Asian descent in a school uniform.

It all starts when, in order to protect "fragile equipment" stored in boxes, the boy and a friend decide to stand in the aisle of the bus while keeping the equipment safe on bus seats.

It's this that agitates the woman, who claims the pair are blocking her view.

"It’s not f---ing right. Sit the f--- down. Get a passport bro," she laughs. "I’m born here, I know what I’m doing. Go back on your f---ing boat and f--- off".

The boy retaliates and tells the woman to get off the bus.

The passenger who filmed the footage, but wanted to remain anonymous, told news.com.au the tirade lasted about 12 minutes and the majority of passengers on board were Asian school children. Do you know the woman in this footage? Email Matt Young at youngma@news.com.au "I would say they were affected by what happened," he said. "The kid reacted like a kid, the best way he could to this person." He said he decided to film the incident and post it to YouTube in an attempt to shame the woman and highlight the widespread racism on public transport. "It's going on and it (racism) doesn't look like it's stopping, I think they should put more effort into getting rid of this kind of behaviour in the public transport system," he said.

The attack took place on the M41 route from Burwood to Campsie in Sydney's inner west last month.

In the footage the woman claims she’s drunk.

"You come to this country and you can do whatever you want. Well you know what, you can't."

Another female passenger is heard to encourage the woman, but cannot be seen on camera.

According to the description posted along with the clip, "the driver had to stop the public vehicle several times".

He is seen to attempt to diffuse the situation but the woman "continued with the abuse the full trip".

The passenger said the bus driver did the best he could with what he had but that it didn't stop the woman from continuing her onslaught.

"No more swearing," the driver says at one point.

The woman claims to be the mother of a 16-year-old son and apologises in the clip, but says "I’m speaking my mind because I’m f---ing over it".

"I’ll shut the f--- up."

This tirade is the latest in a string of verbal and physical attacks on public transport across the country. A State Transit Authority of NSW spokesman said it was an offence for bus passengers to use obscene, offensive and abusive language.

"If it does occur the bus driver should ask the passenger to stop the behaviour," he said. "If they don't comply, the driver can ask them to leave the bus."

Late last year a French woman who was racially abused on a Melbourne bus claimed she feared for her safety, afraid her attacker would "hit" her.

In February, ABC News presenter Jeremy Fernandez was kicked off a Sydney bus after enduring 15-minutes of verbal racial taunts.

In one of the latest attacks, the victim of a Melbourne woman's racist rant said she felt like her "dignity has been removed" as a result of the incident.
