WATCH: Cole Miller’s Brother Makes Powerful Plea To End Street Violence

Billy Miller, who repped Australia in water polo at the 2012 London Olympics, spoke in front of thousands to describe his youngest sibling as “quiet, humble, but very driven”.

But the most poignant of his words related to what we all know: no one should go out for a night with mates, and never come home because of a senseless act of violence.

Cole died 8 days ago, after being struck in the head by alleged attackers Armstong Renata and Daniel Maxwell, who remain in custody facing a charge of unlawful striking causing death.

Among others who addressed the crowd – all dressed in green, Cole’s favourite colour – were Queensland Deputy Premier Jackie Trad and rugby great Wally Lewis.

Wally called for an end to street violence, to huge cheers.

Renata and Maxwell are facing a minimum of 15 years in jail, after being charged under QLD‘s tough new laws to curb coward punches, but the sentiment of today’s crowd was that penalties could be harsher.
