The first Pasefika woman to serve in Victoria's parliament has been denied customary cultural practice of being sung into the chamber by her community.

The Greens member for Northern Metro, Anasina Gray-Barberio will deliver her inaugural speech to the Legislative Council on Wednesday evening.

She replaces outgoing member Samantha Ratnam, who has left the state Parliament to contest the seat of Wills in the upcoming federal election earlier this year.

The incoming member, says she has been "denied the chance to practice a small part of my culture" as she enters the chamber, with 100 Samoan community members to remain outside the doors in accompanying Ms Gray-Barberio with traditional song as a compromise.

National Indigenous Times understands a request was made to suspend standing orders by leave for a short period to allow for the singing inside.

"As the first Pasefika-Samoan person to be entering this Parliament, this is an incredibly significant moment and it's important for me to be able to practice my culture and have my community here for this moment," she said.

"It's incredibly disappointing that before even getting started, I'm being denied the chance to practice a small part of my culture in this place."

Ms Gray-Barberio told National Indigenous Times the request to Parliament was "was denied based on fear of setting any precedents with regards to engagement of the gallery and the chamber" by the major parties.

"It's just singing," she said.

"We come with peace and goodwill to this place of power.

"It's a denial of the reflection of what our society is - that is there is diversity, there is cultural nuance…the institution needs to make space for that, and for the different parts of society that is represented.

"We don't come black and white, we come with different parts of our identity as well."

The majority of the singers are from her local Pacific Islander community, alongside others from across Melbourne, who Ms Gray-Barberio said are also disappointed by the news.

"(They are) People that have raised me, people that I knew growing up, everyday community people, community leaders, elders," she said.

Earlier this month, Māori MPs broke into a haka protesting a controversial bill to reinterpret the Treaty of Waitangi in Aotearoa's Parliament.

"But we only need to look at the powerful moments from the New Zealand Parliament in recent weeks to know that the tide is changing," Ms Gray-Barberio said.

In Canberra, former Minister for Indigenous Australians Linda Burney was sung into Parliament by Wiradjuri woman Professor Lynette Riley on delivering her inaugural speech in 2016.

The moment was replicated during her final speech in August.

Ms Gray-Barberio highlighted the climate emergency faced by Pacific Island nations, and broader social justice points as topics front of mind as she enters Parliament.

"I'd like to continue to put downward pressure on the Government around opening more coal and gas," she told National Indigenous Times.

"I want to ensure that there is social justice for our First Nations and multicultural communities, and ensure that gender equality is also central to conversations as well.

"And our young people being disproportionately impacted in the justice system. That's Pacific Island diaspora, that's African diaspora, and that's First Nations."

Ms Gray-Barbiero stated, of her community, "despite not being able to have the community in there with me tonight, I know they're behind me".

"I'm entering this job with my culture at the forefront. To represent the voices that too often go unheard. Let's get to work."

National Indigenous Times has contacted the offices of Legislative Council President Shaun Leane and leader of the opposition in the Legislative Council, Georgie Crozier, for comment.
