An Australian teen known around the world as "Egg Boy" conceded on Monday that egging a far-Right senator was not the right thing to do, but said the gesture united a world reeling from a white supremacist's alleged massacre of 50 Muslims in New Zealand.

Will Connolly, 17, gave his first television interview since becoming an online hero among many for cracking an egg on Fraser Anning's head as the controversial politician spoke at a news conference after a gunman killed or wounded 100 worshippers at two Christchurch mosques on March 15.

Mr Anning has been widely criticised for blaming Muslim immigration for the racist attacks.

Mr Connolly said he was embarrassed that the international attention he had attracted with the egging, which was caught on video, had distracted attention from the victims in Christchurch.

"I understand what I did was not the right thing to do, however this egg has united people and money had been raised - tens of thousands of dollars has been raised for those victims," Mr Connolly told Ten Network television's The Project programme.
