Controversial US rapper Tyler the Creator has taken to Twitter to announce he has been “banned from Australia” ahead of his September tour, but according to the Immigration Department his application is still under review.

Tyler the Creator - real name Tyler Okonma – made the claim this morning, blaming famed Australian feminist Coralie Alison for getting him barred from the country.

He tagged Ms Alison in the tweet, saying “You won… I’m happy for you”.

However, a spokesperson for the Department of Immigration and Border Protection told 9news.com.au Mr Okonma has not yet been refused entry to Australia but it is considering the risks involved.

“The Department can confirm that Mr Okonma has a current visa application with the Department, and that no decision has yet been made,” they said.

“The Australian Government supports freedom of speech.

“However, the exercise of this freedom involves a responsibility to avoid vilification of, inciting discord in, or representing a danger to, the Australian community.”

Ms Alison is the director of operations for activist and feminist group Collective Shout, which started started a petition urging the Immigration Minister Peter Dutton to stop Mr Okonma from entering the country for his tour in September.

In a letter to Mr Dutton Collective Shout cited Mr Okonma’s lyrics and past behaviour as the reason for its petition.

“Tyler the Creator has received widespread media attention over the span of his career for misogynistic hate speech against women, as well as homophobia,” it read.

“He is renowned for his songs advocating rape and extreme violence against women, including murder, genital mutilation, stuffing them into car boots, trapping them in his basement, raping their corpses and burying their bodies.”

Mr Okonma’s promotors have also announced he has not been banned from the country, but this has not stopped his fans from attacking Ms Alison.

“It would be a very horrible but slightly pleasing accident if someone was to hit @CoralieAlison with a car going maybe 70mph,” wrote one user.

Ms Alison has been re-posting the vicious tweets on her own page, presumably in an attempt to draw attention to the treatment she is receiving.

One user tweeted Mr Okonma saying they had acquired Ms Alison’s home address.

Others sent death threats.
