Australia's radical, anti-Islam right-wing has reacted with horror to Tony Abbott's ousting by Malcolm Turnbull, threatening an exodus to minor parties and more "boots on the ground" in protest.

Former Reclaim Australia leader Shermon Burgess, who now has his own splinter group, the United Patriots Front, uploaded a video to Facebook calling Mr Abbott's ouster a "f.....g pathetic joke".

"This far left-wing prick Malcolm Turnbull is going to turn the country upside down," says Mr Burgess, who styles himself "The Great Aussie Patriot".

"Get ready to put boots on the ground, patriots. We're going to have to up our game. Let's go."
