"I'm optimistic," Albanese told the Australian Broadcasting Corp (ABC) on Sunday morning, according to a transcript.
"Whether it be Shepperton or Sydney or Brisbane, Melbourne, the places I've been, Hobart, Adelaide in the last week, have been extremely positive."
Albanese's centre-left Labor government backs the referendum, while the opposition Liberal-National conservatives urge a "No" vote on Oct. 14.
If the "Voice to Parliament" referendum is approved, it would constitutionally enshrine Indigenous people and set up an advisory body for their input on policies that affect them.
Last month, thousands rallied in state capitals to support the yes campaign, which sees the measure as necessary to boost outcomes for the nation's Indigenous people.
