Jacinta Nampijinpa Price has been given a new Trump-inspired shadow portfolio in a federal Opposition's shadow cabinet shakeup.

Senator Price, a Warlpiri/Celtic woman, has been given the responsibility of a new platform - "government efficiency" - which is touted as a solution to help crack down on "wasteful spending".

Opposition leader Peter Dutton said this includes the $450 million spent on the "divisive Voice referendum".

"Jacinta will be looking closely at how we can achieve a more efficient use of taxpayers' money, where possible, at a time when a major cause of homegrown inflation is rapid and unrestrained government spending," Mr Dutton said.

"Jacinta's outstanding contribution to the Coalition message will stand her in good stead for this new position."

The reshuffle also means the Coalition, despite criticism from Labor about a gender imbalance, now has the same number of women on the front bench and the government.

Senator Price, a former Deputy Mayor of Alice Springs, was the face of the No campaign during the unsuccessful Voice referendum in 2023 and has led the criticism of the government for what she has argues is a failure to support Indigenous communities in the Northern Territory.

"It is an immense privilege to have been appointed as Shadow Minister for Government efficiency within the Coalition," she said on Saturday.

The new role seems to echo the newly created position of US Department of Government Efficiency (DOGE), led by Elon Musk, under the Donald Trump presidency.

Peter Dutton said this week he would have a much better relationship with President Trump than Prime Minister Anthony Albanese, and some have likened Mr Dutton's 'culture war' attacks to the tactics and policies of the new US President.

Senator Price said the new role would "complement the work I will continue to do as Shadow Minister for Indigenous Australians".

"The Coalition has already committed to undertaking an audit of expenditure in Indigenous affairs for the very purpose of ensuring efficiency," she said. "I look forward to the complementary task of increasing efficiency more broadly and ensuring government priorities align with the priorities of everyday Australians."

Arguing the Labor has implemented a "devastating amount of government waste," which has resulted in "increased spending by $347 billion," the NT Senator said it is "more important than ever" to make cuts to "government waste" as well as ensuring the "government is operating as effectively and efficiently as possible".

"This waste has made inflation and the cost-of-living crisis significantly worse, and all Australians are now paying the price. That is why it is more important than ever to cut government waste and ensure that government is operating as effectively and efficiently as possible," Senator Price said.

The outspoken Senator earned the ire of many when she told the National Press Club in 2023 for arguing there are "no ongoing negative impacts of colonisation", and recently has led calls for a full audit on Indigenous organisations, as well as Land Councils, criticising moves by the government to block them.

All organisations that receive government funding are already subject to audits on a regular basis.

When an inquiry into Native Title bodies was voted down by the government in September, after the Native Title Council said it would cause "further politicisation and division," Senator Price said, "we know that these bodies are not functioning the way they could be, and the Albanese government is shutting down any attempt to get them back on course".

Whilst she has been criticised by some, she is widely admired by many conservative voters and a Resolve Poll in December found her to be the most likeable Coalition MP and has led the government messaging on a number of key issues.

Elsewhere in the reshuffle, Senator Kerrynne Liddle was announced as the shadow minister for Indigenous health services, and the shadow energy and climate change minister.

The Arrernte woman, who is the first Indigenous federal member of parliament from South Australia, has been critical of the government taking away the cashless debit card (CDC) from some remote communities, and has also called for more transparency from the federal government on funding designed to reduce youth crime.
