Peter Dutton has never been so popular on social media - and we're not talking about Australia's likely new prime minister.

A 30-year-old African American who shares the same name as the former home affairs minister has been inundated with messages - both supportive and hateful - on Twitter since the leadership move against Malcolm Turnbull began.

"I wish the people of Australia would look at my profile and realize I'm a 30 yr old black man before sending me tweets and DMs," @PeterDutton5 posted on Thursday morning.

Mr Dutton from Austin, Texas, was subsequently inundated with support from Australians.

The 30-year-old told AAP he was "enjoying" his new-found fame and that Australians had been "more than pleasant" after they realised he wasn't running for the Liberal leadership.

And if he leaves soon, he may just make tomorrow's possible leadership spill.
