Fronting press ahead of tonight Australian Of The Year awards, Sam Johnson revealed he was there on behalf of sister, Connie, who sadly passed from a long battle with breast cancer last year.
"My sister set me a very clear task, and that was to remind every single young mum and woman to be breast aware," the Love Your Sister founder said.
"There's new mums popping up everyday, my work will never finish."
"I stand here on behalf of my sister Connie, nobody nominated today is here solely for what they've done, every nominee is very well supported by great teams around them."
"I've lost one half of my team, and I'm just adapting to trying to get it done without her."
