A woman who racially abused a school boy on a public bus in Sydney has escaped conviction.

Susan Bernobich hit the headlines when her racist tirade was captured on a mobile phone by another passenger in May this year.

In it she is seen demanding the Asian school boy "sit down","get a passport" and "get back on your boat".

Court documents show she also abused three other Asian passengers.

She has since apologised to her victims and today pleaded guilty to using offensive language.

The magistrate issued a bond without conviction accepting the woman was genuinely contrite about what she had done.

The court heard she had been intoxicated at the time with a number of issues boiling over in her life.

Ms Bernobich last month appeared on Channel Nine's A Current Affair to apologise for her actions.
