The Morrison government has banned right-wing provocateur Milo Yiannopoulos from entering Australia in a fresh crackdown likely to infuriate his conservative supporters but please critics who believe he is anti-Semitic.

The Sydney Morning Herald and The Age can reveal the controversial speaker was told this week his visa application had been rejected and he cannot enter Australia.

He has a month to appeal the Department of Home Affairs decision, which was made on character grounds.

In June last year Paypal suspended Yiannopoulos after he used the online payment system to send $14.88 to a Jewish journalist.
