An Australia Day party featuring the Nazi flag has been slammed as "racist" and "ignorant".

The Kalgoorlie event attracted attention when images of the flag and a map of Australia complete with a swastika cut into the lawn were shared on social media with accompanying captions, "stay white Australia", and "happy victory day".

The "victory day" party was condemned by Goldfields-Esperance District Acting Superintendent Tony Colfer, who told ABC police were investigating the matter.

"We don't tolerate this kind of behaviour in our community," Superintendent Colfer said.
