Opposition leader Peter Dutton has reaffirmed his plan not to stand in front of the Aboriginal and Torres Strait Islander flags if he becomes Prime Minister, despite criticism that his position is divisive and unnecessary.

Last year, with the Coalition seemingly on track to win the election and in the wake of Donald Trump sweeping to power in the US with a mandate to attack "woke" policies, Mr Dutton told Sky News he would only display the Australian flag at press conferences, arguing that flying the Aboriginal and/or Torres Strait Islander flags would be "dividing our country unnecessarily" and sending a "confusing message".

However, despite polling indicating Mr Trump and policies are increasingly unpopular in Australia, and Labor's apparent success with a strategy of likening the Opposition leader to the President, Mr Dutton stood by his stance on Saturday.

"My policy to stand behind one flag is because I want our country to be united under one flag," he told reporters on Saturday.

"I want our country to be as good as it can be, and we can't be as good as we can be if we're separating people into different groupings.

"Every Australian, whether you came here as a migrant from Greece or from Asia or any part of the world in the 1800s or you came here in 2018 or if you can trace your family tree back 60,000 years, we are all equal Australians."

The Opposition leader appeared to suggest that rejecting the Aboriginal and Torres Strait Islander flags would somehow help close the gap.

"We can respect the Indigenous flag and the Torres Strait Island flag, but we unite under one flag, as every other … comparable country does, and that's how we can help close the gap," he said.

There is no evidence, either presented or hypothesised, which shows removing the flags representing Indigenous people from press conferences will address the alarming discrepancy in key indicators experienced by First Nations people across the country.

Last year, VACCHO chief executive Dr Jill Gallagher said Mr Dutton was using the flag comments to promote the "very division he is pretending to address". She argued all Australians should "take pride" in the fact the country has the oldest living culture in the world.

"Rather than ignore our history, we should stand up and be proud of Indigenous culture, because it is a gift for all Australians," Dr Gallagher said at the time.

"Mr Dutton's comments only create further confusion and division in this country at a time when we should be coming together as one."

Aboriginal and Torres Strait Islander Social Justice Commissioner Katie Kiss was equally critical: "Whether you stand in front of the flags or not has no impact on non-Indigenous Australians or their rights - nor does it cost anything to keep the flags in place."

"This is petty/divisive/ unsophisticated politics - surely being a government that addresses Indigenous disadvantage, generations of policy failure and eradicates racism (in all its forms) is what should be election commitments expected by those who put themselves forward to lead the country," she said at the time.

Mr Dutton, who walked out of Prime Minister Kevin Rudd's apology to members of the Stolen Generations in 2008 and played a significant role in the defeat of the Voice referendum by uttering the slogan "if you don't know, vote no," last year said the country only has one national ensign.

However, the National Museum of Australia states: "Australia's national flags – the blue ensign, the Aboriginal flag and the Torres Strait Islander flag – are important symbols."

Some media pundits have urged Mr Dutton and the Coalition to adopt more conservative and culture war-based policies, largely supporting calls to not stand in front of the flag.

They have also labelled Welcome to Country ceremonies as divisive - without evidence.

On Friday, a notorious Neo-Nazi shouted over Bunurong Elder Uncle Mark Brown delivering the peaceful welcome at the city's Shrine of Remembrance as part of the Anzac day ceremony—something criticised by Mr Dutton and the Prime Minister.

National Indigenous Times has viewed several explicitly racist, unmoderated comments on mainstream media platforms supporting Friday morning's hecklers.

Earlier this month, photos revealed opposition spokesperson for Indigenous affairs, Jacinta Nampijinpa Price, pictured wearing a Donald Trump "Make America Great Again" cap, something she later labelled a "joke".

Senator Price has also defended the Coalition taking preferences from One Nation, the party derided as racist and with a leader found guilty of breaching section 18c of the Racial Discrimination Act for racially discriminatory social media comments regarding NSW Senator Mehreen Faruqi.
