A Perth couple have described how an alleged racial attack on their street has impacted on their children.

Tumaini Eliazery told 9NEWS his children often ask their mother if they are really "monkeys" after the bizarre and shocking encounter.

A video posted on Facebook yesterday shows a woman poking her head over a fence and yelling allegedly racist, expletive-laden slurs across the yard.

"I don't deal with monkeys, get away monkey. Go on now, you f-----g monkey," the woman yells.

"You yellow-eyed mother f----r. Get back to where you come from you black c--t. Get out of this place, nobody wants you."

The footage shows the situation escalate, as a woman arrives in the front courtyard of a neighbouring property, allegedly brandishing a crowbar.

There is a subsequent tussle which allegedly left Mr Eliazery's partner Brenda Ojwang with a bloody eye.

The clash allegedly began over the sound of children playing. (9NEWS)

"I was planning, how am I going to explain to the kids about what just happened," Mr Eliazery said.

"They ask questions now and then, they ask questions like, 'Mummy are we really monkeys?'."

Mr Eliazery is a refugee from Congo and a self-employed cleaner who has lived in Australia for eight years.
