LINDSAY LI was waiting for a lunchtime bus when she was subjected to a racist tirade so bad she feared a physical attack.

Ms Li was in Willoughby, on Sydney’s north shore, catching the citybound 273 bus at noon on Wednesday when she alleges a woman approached her, spat on her and then struck her with her trolley.

They both got on the bus where the woman turned towards Ms Li and began verbally abusing her, which Ms Li captured on her mobile phone.

She uploaded the video onto her Facebook page, which has been flooded with concern from horrified friends and outrage at the woman’s actions.

“So this happened to me today. It’s unbelievable the amount of hate one person can spew out,” she wrote online of her ordeal.

The woman can be heard on the video telling Ms Li “we all know what you are, China”, and to “take your f***ing language and piss off, f***ing chink”.

She also accuses Ms Li of selling drugs and calls her a “f***ing ugly f***ing chink”.

Ms Li cannot be heard responding in the video, that lasts well over a minute.

But it wasn’t just the conduct of the woman that upset Ms Li. She claims no one on board the bus who witnessed the abuse came to her aid, including the bus driver.

“I’m disheartened by the lack of response from fellow passengers and even more so by the bus driver. I asked him for help several times and was ignored,” she wrote on Facebook.

Ms Li, a Chinese Australian, told Fairfax she felt so threatened she went to the driver to ask for help. But she got no response.

“I was completely terrified. No one was standing up for me. This woman was so unstable I thought she could physically attack me at any time,” Ms Li said.

She said she was so threatened by the woman, who she claims crossed the road to “target” her, she showed the footage to police, who are now investigating.

The woman in the video looks and sounds similar to someone recorded in August racially abusing an Asian couple eating their lunch in a Sydney park.

Racist abuse at Wynyard Park This woman was filmed in Wynyard Park hurling racist abuse to a couple.

There have been a number of similar racial incidents on Sydney public transport this year. In April a Muslim woman was subjected to a racist verbal attackon the Airport Line where she was told, “all the people that were dying were because of the Muslims in the world and look what’s happening overseas”.

That same month a group of Asian tourists were on the receiving end of a racist rant by a man who asked them, “Do you f***ing speak English?” and “why did you come to Australia?”. Shocking video of the abuse was uploaded to YouTube

A similar incident happened in July on a Newcastle to Central Coast train, where a 55-year-old woman was eventually charged and appeared in court.

In a statement, a spokeswoman from State Transit said the company did not condone racism on its buses. “We will be investigating this matter further and, if required, will take appropriate action.

“State Transit works closely with the Police Transport Command and Police Local Area Commands to reduce instances of antisocial behaviour on our buses. We encourage customers to report acts of racism to NSW Police.”
