Border Force notes 'legal rape' advocate

The head of the Australian Border Force has "noted" claims from the Return of Kings leader that Australia's borders are "weak".

Daryush "Roosh" Valizadeh, who believes rape should be legal on private property, has been taunting border officials, saying he'll sneak into Australia from Indonesia or East Timor.

"I have the funds to get in by boat through one of multiple weak points. Money is no barrier to the operation," the controversial leader of the anti-women website posted on Twitter.

Australian Border Force commissioner Roman Quaedvlieg offered a quip response soon after.

"Noted," he said in a tweet.

Immigration Minister Peter Dutton on Wednesday said there was no evidence to suggest Mr Valizadeh had applied for a visa.

"I think this is a publicity stunt by somebody who has mental health issues," Mr Dutton told Sky News.
