Queensland police are hunting a man who was filmed racially abusing a Muslim woman and her children before exposing his bare bottom at them.

The woman, who does not wish to be identified, was waiting for her husband outside a Logan shopping centre on Wednesday morning when the man started "aggressively screaming" at her.

"'What are you looking at, you f---ing Muslim?' he screamed at me," she told Mail Online.

"'They're all terrorists, look at those suckers, they’re all unemployed, they come to Australia on boats, they bludge off the dole,' he was yelling. He was so aggressive and hateful."

The man paces around her car menacingly before pulling down his pants and flashing his bottom at her, as the woman filmed him on her phone.

The woman said she feared most for her children.

"They were so quiet while it went on and later on were asking questions, like, 'Mum, why did he say f---ing muslim?', why did he show his bottom?'" she said.

The woman, who was wearing a niqab which only revealed her eyes, said she was forced to helplessly endure the tirade as he did not have the car keys to drive away or close the window.

Many people looked on and laughed at her situation and none stepped in to help, she said.

She said she called police twice but claims they did not come to help or even take her details until she reported the incident in person.

The woman, a German national who converted to Islam 16 years ago, moved to Australia in 2006.
