Federation Council in New South Wales is on the brink of removing Aboriginal and Torres Strait Islander flags from its chamber and official flag poles.

Mayor Cheryl Cook and four other councillors voted for the measure, with four members opposed.

The amendments to the Council's draft Aboriginal and Torres Strait Islander protocols would see the flags flown only during particular weeks and events, such as NAIDOC Week and National Reconciliation Week.

Wiradjuri advocate Buddy Oldman told 7News the flags should remain.

"They are powerful and they are strong, and they create a unity and sovereignty that helps people understand that we have a past," he said.

According to Federation Council's own website, in an article published in 2022: "The Aboriginal and Torres Strait Islander Flags are powerful symbols of unity and strength for Aboriginal and Torres Strait Islander Peoples. Flying the Aboriginal and Torres Strait Islander Flags is one of the most widespread and fundamental ways councils can recognise and respect Aboriginal and Torres Strait Islander Peoples."

Mayor Cook said Australia's Blue Ensign is "the preeminent symbol and unifying symbol of the entire nation".

"That includes all of our friends, Aboriginal and Torres Strait Islander, and also the beautiful people who have chosen to make this country their home," she told 7 News.

Under the draft protocols Welcomes to Country would still be a option for special events held by the Council - but would require approval.
