Before her mum took her own life, Brooke, who was one of five kids, watched her struggle with a drug addiction, which she explained it to be "quite volatile".
"Some times I remember getting really good and some times I remember getting really bad. It had gotten so bad that we were once removed from school and put straight into a foster home without her knowledge," she said.
Brooke also revealed that she felt she didn’t have "stability that was normal", and she was surrounded by things that kids "shouldn't be exposed to" at such a young age.
"I figured out that the way that I lived wasn't exactly normal when my brothers and I went into foster care. We were treated well in care and that became the comparison that helped me to develop expectations," she told NW.
In her TED Talk, How Do You Introduce Yourself?, Brooke also opened up about how at her mother's funeral, she was sexually abused while she was sleeping.
"I don't remember how I processed that information or how I was feeling in that time, but what I do remember is I found a phone book and a house phone and I looked up my dad's name and I found a number and dialled," she said.
Brooke eventually went to go live with her father, which she described as "complicated", as she spent more time under the care of her step mum while her father was away at work.
She was later kicked out of home at the age of 15, and was taken in by a teacher - but not before she struggled with her self worth.
"I'd had to take care of myself and I remember the same feelings I had at 11 came rushing back when I was 15 - 'Why won't I be loved? Why will I never be good enough? And why do I honestly keep bouncing from home to home?'"
Despite everything she faced growing up, Brooke found the strength to overcome it all and become a role model for her community.
"All my brothers and [me], we didn't really have a lot of strong role models so creating that myself was my inspiration," she said.
Taking on the role as a youth worker, Brooke helps run programs for young people, and expressed how much she loved her job to NW.
"Growing up I always wanted to give back to my community in any way I could. Whether that was teaching or working in health service," she said.
She added that she didn't really want the life that she had, so she focused on "whatever I needed to do" in order to have a better life and to help young people in a similar situation.
"I discovered what I'm passionate about quite young, and it's only going to get better for me down the line because I love every single thing we do."
Sadly, Brooke was struck by another family tragedy in early August this year, when she received the news her sister Kye had died.
"I do like to think I live a very private life but I kinda felt like I wanted to share with you where I'm at," she shared on Instagram.
"On the 11/8 I had just received news that my sister passed away. I've been trying to process that on my own being stuck in a Sydney lockdown without my family, off-country and by myself.
"I've thankfully had huge support from production and friends working tirelessly to get me back into WA."
Two days after her sister passed away, Brooke was granted a G2G pass to travel to Western Australia so she could mourn with her family and attend her sister's funeral amid the state's strict border closures.
