Exasperated peak Aboriginal bodies are repeating a call for a greater input into the Government's refresh of its Closing the Gap strategy, saying a formal request in a letter sent last month was ignored by all states bar one.

Key points: State and Territory governments plan to endorse new Closing the Gap strategy targets next month

State and Territory governments plan to endorse new Closing the Gap strategy targets next month The Northern Territory was the only government to respond to the group's first plea

The Northern Territory was the only government to respond to the group's first plea Groups don't want new strategy decided by "governments alone"

The group wants governments to hold off on plans to endorse new targets at the next COAG meeting in December and agree instead to work on them with Aboriginal groups in a formal partnership.

In a second letter sent last week and made public today, the coalition of 13 health groups, land councils and social and legal services warned against decisions on the new policy being made by "governments alone".

"The gap won't close without our full involvement," the letter reads.

"All of us believe it is essential that agreement is reached on the Closing the Gap Refresh policy between Indigenous organisations, on behalf of communities across Australia and Australian governments."

The peak bodies said they had not been shown the proposed new targets that would be discussed at COAG.

And they said consultations earlier this year should not be used to justify agreement next month because they had been rushed and lacked detail.

"We do not accept that we have been properly consulted, let alone given the opportunity to negotiate a mechanism that allows a proper partnership to be put in place in relation to the design, delivery and monitoring of Closing the Gap," the group's letter states.

The Northern Territory was the only government to respond to the group's first plea last month, but did not agree to boycott new targets until a partnership with Indigenous groups was put in place.

The Federal Government announced plans to overhaul the 10-year-old Closing the Gap policy last year, with six out of seven targets not then on track.

Three out of the four targets that expired in June this year were unmet, including closing the gap in school attendance and halving the gaps in unemployment and school literacy and numeracy results.

A group of more than 60 Aboriginal and Torres Strait Islander people chosen by the Government gave advice in February on the refresh strategy.

That group recommended that existing targets be kept and reviewed, and new targets be introduced for areas including justice, economic development, culture and healing and eliminating racism and discrimination.

The group said the Government should negotiate specific targets in the proposed areas with Indigenous people and representative bodies.

Indigenous Affairs Minister Nigel Scullion and his department have been contacted for comment.
