Victoria Police have charged a man over the booing which disrupted the Anzac Day dawn service in Melbourne/Naarm earlier this year.
During a Welcome to Country at the Shrine of Remembrance, hecklers shouted over Bunurong Elder Uncle Mark Brown, demanding the ceremony be stopped. Their calls were quickly drowned out by applause from the crowd.
On Tuesday, police arrested a 23-year-old man from Mooroolbark. He was charged with behaving in an offensive manner in a public place, offending against decency, and taking part in a disturbance.
It was confirmed the man was arrested alongside Neo-Nazi leader Thomas Sewell outside Melbourne Magistrates' Court the same day. He also faces charges over the attack on Camp Sovereignty on Sunday.
The man is due to appear in Melbourne Magistrates' Court on 17 November.
The booing sparked widespread condemnation at the time, dominating headlines for days.
"To pierce the sombre silence of the Dawn Service is more than disrespect — it dishonours all who have served, fought and fallen," Premier Jacinta Allan said.
Police were also seen escorting known Neo-Nazi Jacob Hersant away from the Shrine that morning.
In a statement, police added: "On the day, a 26-year-old man from Kensington was interviewed and released pending summons in relation to offensive behaviour and was directed to leave the area."
First Peoples' Assembly of Victoria co-chairs Rueben Berg and Ngarra Murray said: "We stand in solidarity with Bunurong Elder, Uncle Mark Brown, and acknowledge his strength and resolve during the disruption."
The incident fed into the leaders' debate two days later, when the then-opposition leader, Peter Dutton, argued there should be fewer Welcome to Country ceremonies.
