It's her future, and that of her three-year-old son and 12-year-old sister.
Ms Cama, a Wiradjuri and Pasifika Fijian woman, co-chairs the Uluru Youth Dialogue which is dedicated to advancing the Uluru Statement from the Heart - the invitation from Indigenous people to walk with them for a better future.
"We just don't have the privilege of not working for positive change, it's too important," she told AAP.
Ms Cama will spend Saturday 'poll jumping', going from booth to booth in Sydney, yarning with people about the Uluru Statement and seeing if she can reach voters' hearts and minds, as she has been for months.
"I've been feeling the love - I don't doubt this is going to get over the line at all," she said.
"My personal experience is that it's super positive on the ground, there's just so much positivity out there.
"At the end of the day, it's about Australians accepting the invitation in the Uluru Statement."
It's been a bruising campaign for Indigenous people and especially those on the front line, including Ms Cama.
"I'm hopeful that we're going to win," she said.
"The racism and the misinformation has been difficult for First Nations people but there's momentum, we've seen a lot of people switch on in the last week.
"So, hopefully, people get into the booth, they read the simple question whether they agree to changing the constitution to recognise us through a voice and they can answer that simple question by writing 'yes'."
In order to succeed, the referendum needs a double majority - more than half of all formal votes across the country, and at least four of the six states.
