First Peoples' Assembly of Victoria Co-Chair and Gunditjmara man, Reuben Berg, cast his vote for the Voice referendum on Wednesday in Box Hill.
Mr Berg, who was elected in July, said the entire process has been exhausting for all First Nations people across Victoria, but he was hopeful of a Yes result on Saturday.
"For too long Aboriginal people haven't been heard, that's why we're asking for a voice," he said.
"Voting Yes shows you care about recognition, about listening and better outcomes for our communities."
Talking to National Indigenous Times as he cast his vote, he said the toll on Indigenous Victorians has been immense.
"It's been hugely exhausting," he said.
Highlighting the toll it's taken on people trying to disprove rampant misinformation which has been prominent during the campaign - Mr Berg said it "exhausting."
"Every time we put our voice out there, to have so much negativity come back and have to try and deal with so much misinformation and disinformation; every time our community comes out and says something about this really important initiative, it's it's really quite overwhelming at times for our community," he said.
"Many of us are just hopeful for the weekend when it can be over.
"We're very hopeful we're going to get a yes, but hopefully we can at least move forward and focus on other things in our lives."
Mr Berg, along with fellow co-chair Ngarra Murray, noted that Victorian First Nations people already had a voice, and were already negotiating Treaty with the government, but were hopeful this could be replicated at a national level.
"It's only natural that we want First Peoples in other states and at a national level, to also benefit from the pursuit of Voice, Treaty and Truth," Ms Murray said in an op-ed on Wednesday.
Voice to Parliament referendum voting will be held on Saturday, with the Australian Electoral Commission telling voters to refrain from wearing any Yes or No paraphernalia within six metres of the polling place, as to not fall foul of campaigning laws.
