UPDATE: POLICE will prosecute Sue Wilkins, the woman who has apologised for a racist rant on a Newcastle-bound train.

Ms Wilkins has said she will seek counselling over her diatribe, which has received widespread attention on social media.

Describing what she did to ninemsn, Ms Wilkins said "it's not nice what I did to that lady". 

"It wasn't nice to say that to her because it's not nice when people say that to me ... call me white trash and fatso," she said.

"I know how it hurts and I shouldn't be saying it to other people."

"I had a rotten day, I've been chasing work for quite some time now. It's awful what I said to that woman, I do agree," Ms Wilkins said.

"There's no excuse to rant at people like that."

"It's awful and I wouldn't wish it on my worst enemy, regardless of any race."

“CAN’T you get an Aussie girlfriend? You had to get a gook,” this was just part of a shameful and racist tirade delivered by a woman riding on a train bound for Newcastle.

The woman, who appears to be in her 50's, was upset because other passengers would not give up their seat for her.

The woman first takes aim at a man who is understood to be sitting next to an Asian woman.

“Look at the bogan, he has got a gook.”

Gook is a derogatory term referring to Asians which came to use during the Vietnam War.

Her abuse then shifts to the woman.

“Why did you come to this country? This is our country.”

The woman then attempts to imitate the passenger’s accent.

Watch the tirade in full below: 

Other passengers quickly rush to the couple’s defense telling the woman to “shut the **** up.”

Even youngsters are not spared her wrath as she verbally attacks a mother because her children are seated.

The woman is seen calling the police asking for them to board the train at Strathfield.

On the video she can be heard telling the police her name is "Sue Wilkins".

The incident was filmed by a passenger and uploaded to YouTube took place near Strathfield after the train departed from Sydney.
