An Australian share house rental company has deleted its online presence after sending out an email its tenants labelled "racist" and "unacceptable".

On Monday Sydney-based Sweet Potato Living, which advertises rooms through Flatmates.com.au, sent an email with different instructions for Australian and non-Australian tenants, telling foreign nationals who have lost their jobs to immediately leave the country. The email has now been shared in various Facebook groups.

"If you are from another country and have lost your job and have waited this long, YOU ARE BEING IRRESPONSIBLE FOR DOING SO!!!!" the email, signed only by the company's "help and maintenance" department, reads. "Go back home to your friends and family and live through this crisis with their support as many non-Australians have already done."

When Mark — a pseudonym to protect his privacy, as he remains a tenant of Sweet Potato Living — read the first two paragraphs of the email he said he made a cup of green tea because he knew the rest of it would make him angry, and he was right: “The email just got worse and worse”.

"I was absolutely disgusted with what I read," the 20-year-old told BuzzFeed News.

"It was incredibly racist and incredibly hurtful to not only foreigners but anyone else who might be struggling.

"It is un-Australian what they’ve said. This is not what this country is about."
