An Australian teenager who broke an egg on a controversial far-right senator’s head says he has given almost A$100,000 to survivors of the Christchurch mosque attacks.

Will Connolly egged Fraser Anning in March – prompting people to flood him with donations to pay his legal costs.Mr Anning had caused fury a day earlier when he said, on the day of the shootings, Muslim migration was to blame for them.Fifty-one people died in the attacks.

On Tuesday night, Mr Connolly announced on Instagram the money raised from two GoFundMe pages, a total of $99,922.36, had been donated to the Christchurch Foundation and Victims’ Support.

“For those of you who don’t know, there were two GoFundMe pages set up to help cover the cost of my legal fees and to ‘buy more eggs.’“Gratefully, Gordon Legal acted pro-bono for me so I don’t have any legal fees.“I decided to donate all monies to help provide some relief to the victims of the massacre … it wasn’t mine to keep.”

Victoria Police decided not to press charges against either party in the March 16 incident.

Senator Anning, 69, has also avoided charges after striking the boy once he was egged.

“Investigators reviewed CCTV footage of the incident and both parties were interviewed,” police said in a statement.

“The 17-year-old Hampton boy has been issued with an official caution … A decision has been made not to charge the 69-year-old man. On assessment of all the circumstances, the 69-year-old’s actions were treated as self-defence as there was no reasonable prospect of conviction.”
