The footage showed Anning being watched eagerly by the young man, before he gets his phone out, starts filming, and smashes the egg.
Musicians from all over the world have shown their support of Will Connolly, the 17-year-old Victorian teenager known as Egg Boy.
Senator Anning was being interviewed by a Melbourne newspaper reporter at Moorabin when the 17 year-old boy from Hampton, an affluent suburb in Melbourne, broke a raw egg over the back of his head.
The boy was later take away by police and released without charge.
"I am utterly opposed to any form of violence within our community, and I totally condemn the actions of the gunman", Anning wrote in a statement.
American actress Chelsea Peretti tweeted: "why did egg boy vid make me cry". A GoFundMe page has already raised more than $8,000 to pay for his legal fees and "more eggs", according to the post. "He should be, frankly, ashamed of himself".
Both major parties can go no further than censuring Mr Anning as he is an independent.
In Christchurch, New Zealand this past Friday, 50 people were killed and 50 injured in a shooting that targeted two mosques.
Earlier on Saturday, Minister for Home Affairs Peter Dutton instructed Senator Anning not to make any further public comment on the matter. "This is the outcome of the Islamophobic and racist hate", Dr Faruqi wrote last Friday in a message on Twitter.
News.com.au political reporter Sam Clench wrote: "The Australian senator now spewing racist garbage in response to the New Zealand mosque attack got 19 votes at the last election".
