Indigenous Senator Jacinta Nampijinpa Price says the Coalition will look to halt federal funding for Welcome to Country ceremonies if they win the upcoming federal election.

Senator Price, whose position as shadow minister for Indigenous Australians has been supplemented with the added portfolio of government efficiency after a reshuffle at the weekend, has outlined a future Coalition government's plans.

"Going forward, what has come out of the result of the [Voice] referendum, is that Australians want to see taxpayer dollars work more effectively for them," the Warlpiri/Celtic Senator told ABC News on Friday.

"Right across the board, [but] certainly for marginalised Indigenous Australians.

"Australians want to cut the waste, they want to make sure that outcomes are coming to life with the way in which taxpayer dollars are being spent by their government."

The Sunday Telegraph revealed earlier this month, under the headline "Welcome to cash country," that the federal government had spent $452,953 on Welcomes to Country over the past two financial years, which involves paying Traditional Owners for their time and work.

As a comparison, as opposition leader, Peter Dutton will receive $432,239 in one year and Prime Minister Anthony Albanese $607,471 over the same period.

National's leader David Littleproud argued "Welcomes to Country have become more about the money than the meaning".

"There's no need to spend that sort of money for departments to have their own Welcome to Country, cultural training on how to do Welcomes to Country. That's obscene," he said.

Senator Price expanded on Mr Littleproud's comments, arguing she would look at an audit of the "billions of dollars that are spent in the Indigenous space, so that we can understand where that can be better spent", focusing specifically on the role of federal bodies like the National Indigenous Australians Agency.

She argued the country shouldn't be spending $450,000 power government term on Welcome to Country ceremonies, arguing they aren't "actually improving the life of a marginalised Indigenous Australian".

"That kind of funding could be redirected to actually improve the lives of marginalised Indigenous Australians, as opposed to being used for what is effectively a welcoming ceremony, many of which have now become quite politicised," Senator Price said.

"I don't think it's necessary to have to spend so much money on something that's not really helping our most marginalised."

The NT Senator has run afoul of numerous Indigenous organisations due to her position on ways to close the gap, including self-determination.

Last year Senator Price rejected a Productivity Commission report which called for self-determination to help close the gap, going against the views of many Indigenous health, legal and human rights groups who argue decisions that impact Indigenous people should be put in the hands of First Nations people.

She also reiterated her calls this week for an inquiry into land councils' statutory authorities, which was backed up by Mr Littleproud, who said his party would support breakaway groups from the Territory's four land councils: Northern, Central, Tiwi and Anindilyakwa.

Any change wouldn't fall under the Commonwealth's remit, and instead would require amendments to the 1976 Land Rights Act.

Senator Malarndirri McCarthy reacted to Senator Price's new portfolio by saying she was worried this would only mean cuts to vital services for Indigenous Australians.

"The Coalition is really focused on culture wars, and it really is quite disappointing...we know that the Opposition leader walked out on the Apology [to the stolen generations in 2008]," she told ABC radio Darwin on Friday.

"He won't stand in front of the Indigenous flag. And now he doesn't want elders doing Welcome to Country. ...if you look at tourism in this country, the large percentage of tourists come to Australia domestically and internationally - especially here in Central Australia - for Indigenous culture.

"So, what is it? Which is it? Who's the waste? Is it Aboriginal people? I think we have to really ask the question, where is the Indigenous plan for the future with the Coalition and with Senator Price?"
