City of Sydney's first Aboriginal councillor Yvonne Weldon says it's time for a change on announcing her candidacy for Mayor.

Three years on from making history with election to the council - the first Aboriginal person to do so in its 180-year history - as an Independent, Weldon, a Wiradjuri woman who grew up in the city's inner suburbs, said "I'm running to build a better future".

Elections are set for Saturday, September 14.

Councillor Weldon feels it's an opportunity for residents to opt for a "refresh".

Current Lord Mayor Clover Moore has been in the job for more than two decades.

"I definitely feel like it's time for a refresh, and no one better than myself being a First Nations person, a Wiradjuri woman...it's time," Councillor Weldon told National Indigenous Times.

There are key areas to address in her vision to "make sure that the city is inclusive and vibrant and humming with opportunity and accessible for all".

"We need to actually have more affordable housing, accelerate a green economy, and also make sure that our creatives and artists and our local businesses actually continue to exist," she said.

Asked if it's renters, first-home buyers or low-income families and public housing within Sydney's housing crisis front of mind, she stated "all of the above".

"One of the things I've been raising is around what does affordable rental housing look like, and why are we not having that built on site with the developments?" Councillor Weldon said.

"There's always such a major lag in trying to get affordable and social housing, and more of it, and yet we see these developments just pop up everywhere.

"And why are we not making sure that those developers that are making lots of money actually start to build some of that affordable housing on site?"

Councillor Weldon raised an uptick of council-owned land being handed over to an increased number of housing providers.

She's also flagged a doubling of City of Sydney's Affordable Housing Fund.

"At the moment, it's roughly $10 million. I would like to see it increased to $20 million. There is opportunities to be able to get more out of it," she said.

A long-held concern amongst Sydneysiders - particularly young people - is also in her sights.

She told National Indigenous Times: "I think we need to be supporting our creatives in our young people to be a part of our society, and rather than sort of being pushed out into the suburbs."

"(Oxford Street) it's just continued to decline. And I get continually approached by shop owners and alike around how it's just neglected, and it needs to be refreshed and revived," Councillor Weldon said.

"The City owns a lot of property along Oxford Street…where we do have facilities of our own, we can actually have mixed businesses there, and also have reduced rents for those that are not major companies...when you have local people that actually want to provide services and opportunities, that's where we can support that."

She also believes households and businesses play a role in the in the Council's 2035 net zero targets with rates rebates a potential incentive.

Last year, Councillor Weldon voiced her concerns regarding colonial statues in the City of Sydney.

She said her push for plaque re-writes to reflect a shared history have taken longer than she expected, as well as offering her suggestion for who should be honoured next.

"There still isn't a publicly-funded First Nations person represented in our city, in statue," Councillor Weldon said.

"I think that Patyearang would be the first...I think it's long overdue."

Patyegarang is recognised as leading cultural exchange and helping survive Gadigal language in the early days post British arrival.

"If you were to go back to the projections on the sales of the Opera House on Survival Day this year, there was a projection of Patyegarang and other Aboriginal warriors.

"I think that in the city we need to actually have true representation of the people that represent so much more of what took place in the past, but so much more of what needs to continue into the future of our history and now truth-telling."

There's also another change she would implement; that's proposing scrapping the 'Lord' out of Lord Mayor.

"I will be a mayor of the people and will serve them rather than preside over them...it's about walking with them not thinking that you're superior to them," she said.

Councillor Weldon has previously served as elected chair of the Metropolitan Local Aboriginal Land Council, deputy chair of the NSW Australia Day Council and as a board member of Domestic Violence NSW among a list of senior government positions.
